Bravo. This video is invaluable for those of us just getting started with the Jetson Dev Kit. I was at a loss on what to do to get the demos working. Your instructions are clear and very helpful. They got my system up and running. Thanks!
Thanks for this video it helped a lot and I've successfully installed jetpack 3.2 ... but the README file didn't contain instruction for running backend ..so here it is for anyone trying to run the sample >> ./backend 1 ../../data/Video/sample_outdoor_car_1080p_10fps.h264 H264 --trt-deployfile ../../data/Model/GoogleNet_one_class/GoogleNet_modified_oneClass_halfHD.prototxt --trt-modelfile ../../data/Model/GoogleNet_one_class/GoogleNet_modified_oneClass_halfHD.caffemodel --trt-forcefp32 0 --trt-proc-interval 1 -fps 10
Will Librealsense work with Jetpack 3.2 on Ubuntu 16.04 with the patch you have here github.com/jetsonhacks/installLibrealsenseTX2 ? I see your article here www.jetsonhacks.com/2017/08/14/intel-realsense-camera-librealsense-nvidia-jetson-tx-dev-kits/ will you please add some notes for the new JetPack 3.2 :) Thanks again for the great work you have done!
I have not tried JetPack 3.2, I do not know the answer to your librealsense question. Due to the nature of UA-cam videos, I do not update every time a minor revision is released, i.e 3.1 to 3.2. Because JetPack 3.2 is a developers preview, there's not much reason to add more notes because each version of JetPack already has it's own release notes. Thanks for watching!
hallelujah! Thanks a million for this. I got it to work using 16.04 in a VM. As a newbie, the VM approach was appealing but added a few twists. The jetpack component manager is, uh, ... opinionated and optimistic.
JetPack 3.1 is the current shipping version. I installed and tried to use the backend demo. Turns out a lot has changed between 3.0 and 3.1: The "magic" has changed from "gie" to "trt" which I am translating as TensorRT for the runtime inference engine. Also the directory structure has changed. "video" is now "Video" and "model" is now "Model". Additionally, the models in the 3.0 video don't exist but a "one_class" and "three_class" version exists. I have basically been using the shotgun approach of just picking parameters using a SWAG. No luck so far. Has anyone actually deciphered how to get the new sample program to display the detection of automobiles? I am going to slog through the code, but having a proper command line in a README would sure be nice!! grep has not uncovered a file with up to date information.
The following works for me: nvidia@tegra-ubuntu:~/tegra_multimedia_api/samples/backend$ ./backend 1 ../../data/Video/sample_outdoor_car_1080p_10fps.h264 H264 --trt-deployfile ../../data/Model/GoogleNet_one_class/GoogleNet_modified_oneClass_halfHD.prototxt --trt-modelfile ../../data/Model/GoogleNet_one_class/GoogleNet_modified_oneClass_halfHD.caffemodel --trt-forcefp32 0 --trt-proc-interval 1 -fps 10
That was very helpful, but I got an issue at the end. I successfully flashed the JetPack and it acquired the IP address but the Jetson boots up and goes to page tegra-ubuntu and then gets frozen in this page. Neither mouse nor keyboard works.
This is a very informative video, I'm glad I came across this in time! I have one small issue. My laptop doesn't have a supported GPU capable of training a CNN model to be ported on to the Jetson TX2 and hence no GPU is being detected by the Jetpack in subsequent stages. Which GPU is your desktop running on? And which model GPU would you recommend to have for development purposes? Thanks in advance! :D
I only use that desktop to load JetPack, there is no GPU in it. GPU selection for training is a very broad question, it mostly depends on how much money you want to spend. For entry level, something like a NVIDIA 1070 or better would be a good start. GPUs range in cost from a few hundred dollars to several thousand dollars, and the systems need to be built with enough power to support them. Thanks for watching!
Hi Jim ! Thanks for your clear instructions ! I also have a few questions : I have a host PC with Ubuntu 14.04 which is connected to a "university" network. - For the flashing, can I connect the Jetson TX2 to another ethernet socket (another from the university network) or is the switch setup mandatory ? - If the switch is needed, which model do you use ? Moreover, did you have to do some installation / setup to connect both host and target on it ? - After the flashing is complete, can we simply access Internet on the target via the Wifi module instead of the ethernet cable ? Sorry if this is obvious, I have a poor background in networks =P
The PC must be able to 'see' the Jetson, you must be able to ping the Jetson from PC. There are a couple of network configurations you can choose from in JetPack. The Jetson is connected to the PC via a USB cable for the 'flash', which copies the OS over to the Jetson and puts it into flash memory. After that, JetPack SSHs into the Jetson using the Ethernet connection. The Ethernet connection must be wired at this point. Once it connects to the Jetson, the PC then copies and installs the selected packages. After flashing and installation of packages, then you can use the Jetson standalone, including the wireless. Thanks for watching!
Thanks for excellent walk through tutorial. I managed to flash the Jetpack onto the Tx2. However, I can not run the demo. Somehow the reademe file is different from the one shown in the video. There are no command codes.
This video is from an earlier version than is currently shipping. The current shipping version is JetPack 3.2, the video is for JetPack 3.0. You'll have to hunt down the demo code, I believe that it is on the device somewhere in the samples area. Thanks for watching!
Hi Sir, Thanks a lot for the video. Can you please tell me one thing? Can this JetPack 3.0 detect passengers' wrong movements in real time (if the camera is set up on the bus)?
JetPack is a software installer. You are describing an application that takes development. The Jetson has tools available which can help with this type of development, but it will require work on your part to get the application working. Thanks for watching!
Thanks a lot sir for quick replying! Yes, I know it will require work. One more request sir. Can you please reply to my quora question? www.quora.com/unanswered/Can-the-NVIDIA-JetPack-3-0-able-to-detect-passengers-wrong-movements-in-real-time-from-the-CCTV-footage
Sorry sir. I forgot to edit the question. JetPack is an installer just you said. Jetson is the development tool. Thanks. www.quora.com/unanswered/Can-the-NVIDIA-Jetson-able-to-detect-passengers-wrong-movements-in-real-time-from-the-CCTV-footage-1
Not sure what you mean. JetPack is a software installer application. JetPack flashes the Jetson with the BSP (Firmware + L4T which is a modified Ubuntu) for the given board. JetPack then copies libraries and development tools to the Jetson. There is an option to install Jetson libraries and cross compiler development tools on the PC host computer. This option allows developers to cross compile applications on the PC and then transfer them to the Jetson. Consequently you have the option of developing on the Jetson standalone, or on a PC using cross compilation. Thanks for watching!
Hi, Thank you for your videos. I have a question regarding to the installation of the Jetpack. I have the host installed, but the storage of the virtual machine was fulled during the flashing process. Is it possible to continue installing the Jetpack instead of starting over? Thanks!
be careful, you can NOT Flash the TX2 from the host machine via USB if you are running an Ubuntu VM (it just fails repeatedly mid-flash). Furthermore, you can NOT utilize your NVIDIA graphics card on your host machine for training networks if you are running an Ubuntu VM (there is no virtual pCie support). The Solution is to dual boot. Install a second hard disk with Native Ubuntu, so you can get the full benefit of a native Ubuntu Desktop :D
Great tutorial! But I have two below questions, pls help: What is host system requirements to install JetPack? And is it possible to install on a virtual machine?
Please see the official NVIDIA Documentation as above or ask this question on the official NVIDIA Jetson Developer forums: devtalk.nvidia.com/default/board/188/jetson-tx2/

Hi guys, I have a dumbd question. I am working on a vision system with deepth cameras and i am using a laptop to do that with ROS. I never worked with that board before and i want to know if the behavier of the board will be the same of my laptop? or if i will not have any compatibilaty issues with that board ? By the way, great work. Cheers
It mostly depends on the depth cameras being used. If the cameras have drivers for the Jetson (ARM type of processor), it should work. The usual integration issues apply, of course. If there are no camera drivers, than it can be a difficult task. Thanks for watching!
I know that jetson tx2 board has Ros compatibility. All the cameras and the vision system uses the ROS. The board has a good performance so my only afraid is to have a lot of problems with some libraries like opencv for example. Thanks for you help
hello, sir , i have a question and i hope you can answer it help me. how can i install pycharm on jetson tx2 (with ubuntu 18.04)??? thank you very much
When you start the tutorial, it appears that your TX2 already has Ubuntu up and running. I've just unboxed and set up my TX2, but upon power up (w/HDMI, Keyboard/mouse and ethernet connected) there doesn't appear to be any system on my fresh TX2. Is that normal?
Fresh from the box, most of the Jetsons boot to a command prompt. Once the machine is up, you run an installer to install the GUI. The installed system is a very early version of L4T, and NVIDIA recommends that you flash the Jetson with JetPack to install the latest and greatest. Thanks for watching!
Hi I'm using the Jetson tx2 for a mechatronics project and upon booting it the first time I tried following the 3 instructions that they give us but I get a corrupted files problem. Should I flash the Jetson tx2 please? If yes do I do it by downloading the tegra tar or by following this video? I am at a loss when it comes to what to start with. Please any help would be highly appreciated. Thank you.
I don't understand your question. JetPack is an application that runs on your desktop/laptop PC running Ubuntu. JetPack installs Ubuntu and supporting libraries on the connected Jetson.
@@oldschoolusviandcaribbeanmusic Yes, this is certainly a point of confusion. If you are using the SD card image approach (which is what you should use, especially if you are new to the platform), then you have no reason to use JetPack proper. Once you flash the SD card, you should be good to go!
I really like this video! but I have doubts.. Does the JetPack installer require Ubuntu 14.04 on my host PC (laptop)? Can I use only WiFi network to hook up host pc and jetson tx2?
I finished all installation but end of the all process , i tried to run example that is same as video i can not find backend file to run in my file there are 4 file. What is wrong , is my setup alright? Thanks
This is a good question to ask in the official NVIDIA Jetson TX2 developers forum: devtalk.nvidia.com/default/board/188/jetson-tx2/ There are NVIDIA engineers in the forum to help deal with such issues. Thanks for watching!
Today I know what the problem is. NVIDIA updated JetPack 3.1 and they DELETED the JetPack 3.0 files on their website! So I cannot download the files, which caused the JetPack error. The solution for this problem is to update JetPack to 3.1. And I use the new JetPack and new L4T and I found it is very unfriendly in some functions. That's crazy NVIDIA.
I have not encountered this issue. You can ask on the official NVIDIA Jetson TX2 Developers forum where a large group of developers and NVIDIA engineers share their experience. The forum is located at: devtalk.nvidia.com/default/board/188/jetson-tx2/ Thanks for watching!
In the instruction manual, for installing jetpack it says you need a "Serial cable plugged into the serial port J1A2 UART4 on the target connected to your Linux host directly or through a serial-to-USB converter. Required to setup serial console on the Linux host." How come it was not needed in your install here? Just trying to figure out if I have to go and buy another lead :)
I'm not sure what manual you are reading. This video is for the Jetson TX series. You appear to be describing the serial console on a Jetson TK1. In order to install JetPack In either case, a serial cable is not needed. The provided micro USB to USB cable is used to connect the Jetson to the PC host. Thanks for watching!
Hi, thanks for replying! Rightly or wrongly, its definitely in the TX2 manual - page 8 of this bad boy developer2.download.nvidia.com/embedded/L4T/r27_Release_v1.0/Docs/Jetson_X2_Developer_Kit_User_Guide.pdf?wEcgUYw92MxHVUUSkTBEcjkeHrKxywSn_ocU0Ns9TXPSVp9m8I0fxcCDqIEQOy4MCVcrj7KJBfPEooJsD4y3mysdiilbJ-zFiZKR27506Ygc3lIXcunV43zbE4-7dByeFDsIfSfkdJ_bgXzuBZBTaWLnaPq8rwR1vbIPTw8uZbBvmeRiKetN2A. In any case, your method for getting it up and running worked, which is great! Sadly the readme in tegra_multimedia_api, at least in he version I got, no longer includes the code snippet, so I will have fun hunting for that! Happy jetsoning :)
Glad you got it to work! Maybe the wording seems confusing to you. If you need to access the serial console, you need the J1A2 connected to the host via the serial to usb converter. Here's a video: ua-cam.com/video/eQCJy9iUvTA/v-deo.html That's different than flashing the Jetson, as shown in this video. For flashing, that page states: "A USB Micro-B cable connecting the Jetson system to your Linux host for flashing." The cable is included with the kit.
I tried installing Jetpack 3.2 on a host machine running Ubuntu 16.04.1 LTS, I received the following error: "Installing CUDA Toolkit 9.0 failed". The error said to check the cuda_host_9.0.log file which indicated I should run apt-get update, which I have done. This still did not fix the problem as the "Installing CUDA" pop-up warning came back. Any suggestions are greatly appreciated!
I do not have any experience with this issue. Please ask this question in the official NVIDIA Jetson TX2 forum, where a larger group of developers as well as NVIDIA engineers share their experience.

After flashing, the keyboard & mouse don't work. Even the mouse doesn't seem get the eletricity (the mouse lamp is off). It all work before flashing. Anybody know? My setup are: 1. PC Host : Ubuntu 16.04 64bit 2. Jetson : Jetson TX2 Orbitty Carrier 3. JetPack : 3.3
The Orbitty is a different carrier board, which uses (at the minimum) a different device tree than the Jetson Development Kit. You should follow the manufacturer instructions provided for flashing your Jetson. ConnectTech has a video on the subject: ua-cam.com/video/9uMvXqhjxaQ/v-deo.html
I believe that you have to use a jumper. You will need to look at the documentation for the correct placement. Please ask this question on the official NVIDIA Jetson TX2 forum where a large group of NVIDIA engineers and developers share their experience. Thanks for watching!

Hey, this was a great tutorial, I am apart of a robotics team at my school and we a attempting object or blob detection with opencv. I made it threw the whole installation process with no errors however when I attempt to run a sample it says permission denied. I'm no to sure why this is happing, but you readme file and my readme file are also possible because i installed the new JetPack 3.1. I ended up find the sample but not getting past the permissions problem. Any solutions?
Know it is tell me that my command isn't found. Just to make sure I am doing this correctly. Once I get pass this I feel like it will work however 1.Open Terminal 2.Enter file location/Call Directory 3.sudo "Enter" 4.Enter Pass
Hi ..... JetsonHacks i hve got serious issue during my work on Jetson .. When i turn on my TX2 it starts by displying nvidia icon and after that it donot give any disply On jetson board 2 lights closed to the power button are on and one light left to the fan named (Alert PCI/SATA powered up) is on .. I posted the issue in nvidia forum but i don't understand what to do know.. I seem that u are master of jetson tx2 so i am asking for help ... please help me about this issue and yhe red light which is on i-e Alert PCI/SATA powered up
The lights are as expected. More than likely you have an issue with the monitor. You should be using an HDMI monitor with an HDMI cable. For further debugging, use a serial console connected to your host machine. Thanks for watching!
thanks ..Jetson Hacks for replying... u are absolutely right . altough i am using HDMI monitor 16:9 with HDMI cable but i think the monitor is not well compatible with jetson .....what type of display you are recommending with jetson.?... i mean such monitor which donot create these issues..... again thanks for your reply..

Hi, I tried the tutorial, it is very helpful, but I have a problem, I am not able to see anything on the Jetson display. Can you please help why I have this issue? Thanks in Advance
It is difficult to determine the problem from your description. Do you have a HDMI monitor connected through an HDMI cable to the Jetson? Which Jetson are you using? Which version JetPack are you using?
In general, that will not work on a Jetson. HDMI tells the Jetson how to configure the monitor driver, but the HDMI to DVI converter does not allow the Jetson to talk to the monitor and figure out how to configure it. You end up, as you know, with a blank screen. You will need a true HDMI monitor to work with the Jetson.
Hi JetsonHacks, Thank you so much for your cool video. After flashing completed (terminal logout nvidia ssh at the first time then nothing else did), I logged in jetson tx2 using user-password "nvidia", I could not use sudo.

JetPack 3.1 is the current shipping version. I installed and tried to use the backend demo. Turns out a lot has changed between 3.0 and 3.1: The "magic" has changed from "gie" to "trt" which I am translating as TensorRT for the runtime inference engine. Also the directory structure has changed. "video" is now "Video" and "model" is now "Model". Additionally, the models in the 3.0 video don't exist but a "one_class" and "three_class" version exists. I have basically been using the shotgun approach of just picking parameters using a SWAG. No luck so far.
Has anyone actually deciphered how to get the new sample program to display the detection of automobiles?
I am going to slog through the code, but having a proper command line in a README would sure be nice!! grep has not uncovered a file with up to date information.

I only use that desktop to load JetPack, there is no GPU in it. GPU selection for training is a very broad question, it mostly depends on how much money you want to spend. For entry level, something like a NVIDIA 1070 or better would be a good start. GPUs range in cost from a few hundred dollars to several thousand dollars, and the systems need to be built with enough power to support them. Thanks for watching!
Thank you very much! Much appreciated!
Thanks a lot. Got my Jetson Dev kit started using this video.
You are welcome. Thanks for watching!
Hi Jim ! Thanks for your clear instructions !
I also have a few questions :
I have a host PC with Ubuntu 14.04 which is connected to a "university" network.
- For the flashing, can I connect the Jetson TX2 to another ethernet socket (another from the university network)
or is the switch setup mandatory ?
- If the switch is needed, which model do you use ? Moreover, did you have to do some installation / setup to connect both host and target on it ?
- After the flashing is complete, can we simply access Internet on the target via the Wifi module instead of the ethernet cable ?
Sorry if this is obvious, I have a poor background in networks =P
The PC must be able to 'see' the Jetson, you must be able to ping the Jetson from PC. There are a couple of network configurations you can choose from in JetPack.
The Jetson is connected to the PC via a USB cable for the 'flash', which copies the OS over to the Jetson and puts it into flash memory. After that, JetPack SSHs into the Jetson using the Ethernet connection. The Ethernet connection must be wired at this point. Once it connects to the Jetson, the PC then copies and installs the selected packages.
After flashing and installation of packages, then you can use the Jetson standalone, including the wireless. Thanks for watching!
Hi Raph, which configuration actually worked for you in the end?
Amazing effort from you! This was really helpful for me to understand how to install baseline onto my Jetson TX2. Thank you very much :)
You are welcome, and thanks for watching!
Thanks for this video. Ca I install Jetpack 3 in Jetson Nano?
Thanks, this is really helpful to see it visually!
You are welcome, and thanks for watching!
Thanks for excellent walk through tutorial. I managed to flash the Jetpack onto the Tx2. However, I can not run the demo. Somehow the reademe file is different from the one shown in the video. There are no command codes.
This video is from an earlier version than is currently shipping. The current shipping version is JetPack 3.2, the video is for JetPack 3.0. You'll have to hunt down the demo code, I believe that it is on the device somewhere in the samples area. Thanks for watching!
Thanks
Hi Sir, Thanks a lot for the video. Can you please tell me one thing? Can this JetPack 3.0 detect passengers' wrong movements in real time (if the camera is set up on the bus)?
JetPack is a software installer. You are describing an application that takes development. The Jetson has tools available which can help with this type of development, but it will require work on your part to get the application working. Thanks for watching!
Thanks a lot sir for quick replying! Yes, I know it will require work. One more request sir. Can you please reply to my quora question? www.quora.com/unanswered/Can-the-NVIDIA-JetPack-3-0-able-to-detect-passengers-wrong-movements-in-real-time-from-the-CCTV-footage
I do not have an answer to your question to post.
Sorry sir. I forgot to edit the question. JetPack is an installer just you said. Jetson is the development tool. Thanks. www.quora.com/unanswered/Can-the-NVIDIA-Jetson-able-to-detect-passengers-wrong-movements-in-real-time-from-the-CCTV-footage-1
The question is a broad and general question. I do not know the answer.
why do you need to install the JetPack 3.0 to both the SDK and the Host PC? Couldn't you just do the entire installation inside the SDK machine?
Not sure what you mean. JetPack is a software installer application. JetPack flashes the Jetson with the BSP (Firmware + L4T which is a modified Ubuntu) for the given board. JetPack then copies libraries and development tools to the Jetson. There is an option to install Jetson libraries and cross compiler development tools on the PC host computer. This option allows developers to cross compile applications on the PC and then transfer them to the Jetson. Consequently you have the option of developing on the Jetson standalone, or on a PC using cross compilation. Thanks for watching!
Hi,
Thank you for your videos.
I have a question regarding to the installation of the Jetpack. I have the host installed, but the storage of the virtual machine was fulled during the flashing process. Is it possible to continue installing the Jetpack instead of starting over? Thanks!
Hi Arthur,
I don't think so. Thanks for watching!
be careful, you can NOT Flash the TX2 from the host machine via USB if you are running an Ubuntu VM (it just fails repeatedly mid-flash).
Furthermore, you can NOT utilize your NVIDIA graphics card on your host machine for training networks if you are running an Ubuntu VM (there is no virtual pCie support).
The Solution is to dual boot. Install a second hard disk with Native Ubuntu, so you can get the full benefit of a native Ubuntu Desktop :D
Great tutorial! But I have two below questions, pls help:
What is host system requirements to install JetPack?
And is it possible to install on a virtual machine?
Thank you for the kind words. Please see: developer.nvidia.com/embedded/jetpack-notes

Hi guys,
I have a dumbd question. I am working on a vision system with deepth cameras and i am using a laptop to do that with ROS. I never worked with that board before and i want to know if the behavier of the board will be the same of my laptop? or if i will not have any compatibilaty issues with that board ?
By the way, great work.
Cheers
It mostly depends on the depth cameras being used. If the cameras have drivers for the Jetson (ARM type of processor), it should work. The usual integration issues apply, of course. If there are no camera drivers, than it can be a difficult task. Thanks for watching!
I know that jetson tx2 board has Ros compatibility. All the cameras and the vision system uses the ROS. The board has a good performance so my only afraid is to have a lot of problems with some libraries like opencv for example. Thanks for you help
You're welcome, and thanks for watching!
hello, sir , i have a question and i hope you can answer it help me. how can i install pycharm on jetson tx2 (with ubuntu 18.04)??? thank you very much
What have you tried?
When you start the tutorial, it appears that your TX2 already has Ubuntu up and running. I've just unboxed and set up my TX2, but upon power up (w/HDMI, Keyboard/mouse and ethernet connected) there doesn't appear to be any system on my fresh TX2. Is that normal?
Fresh from the box, most of the Jetsons boot to a command prompt. Once the machine is up, you run an installer to install the GUI. The installed system is a very early version of L4T, and NVIDIA recommends that you flash the Jetson with JetPack to install the latest and greatest. Thanks for watching!
thanks for make this nice video, helps me a lot
I'm glad you found it helpful. Thanks for watching!
Hi I'm using the Jetson tx2 for a mechatronics project and upon booting it the first time I tried following the 3 instructions that they give us but I get a corrupted files problem. Should I flash the Jetson tx2 please? If yes do I do it by downloading the tegra tar or by following this video? I am at a loss when it comes to what to start with.
Please any help would be highly appreciated.
Thank you.
You should follow the suggest procedure by NVIDIA, which is to use the SDK Manager to install JetPack: developer.nvidia.com/embedded/jetpack
jetpack gets installed after the OS, or is the OS included in jetpack?
I don't understand your question. JetPack is an application that runs on your desktop/laptop PC running Ubuntu. JetPack installs Ubuntu and supporting libraries on the connected Jetson.
@@JetsonHacks thank you. i am a rookie, and was thinking the jetson nano needed jetpack after i installed the OS on jetson nano.
@@oldschoolusviandcaribbeanmusic Yes, this is certainly a point of confusion. If you are using the SD card image approach (which is what you should use, especially if you are new to the platform), then you have no reason to use JetPack proper. Once you flash the SD card, you should be good to go!
@@JetsonHacks thank you. your videos are great for newbies such as i am.
I really like this video! but I have doubts.. Does the JetPack installer require Ubuntu 14.04 on my host PC (laptop)? Can I use only WiFi network to hook up host pc and jetson tx2?
Some people have reported success using Ubuntu 16.04 on the host. An Ethernet cable must be used. Thanks for watching!
This is hilarious and informative
Thank you for the kind words, and thanks for watching!

@@JetsonHacks What is the command line for Jetson TX2??
Why are JetPack always downloading repository file and showing "Error"???? I completely cannot open JetPack for installing the softwares on TX2.
This is a good question to ask in the official NVIDIA Jetson TX2 developers forum: devtalk.nvidia.com/default/board/188/jetson-tx2/
There are NVIDIA engineers in the forum to help deal with such issues. Thanks for watching!
Today I know what the problem is. NVIDIA updated JetPack 3.1 and they DELETED the JetPack 3.0 files on their website! So I cannot download the files, which caused the JetPack error. The solution for this problem is to update JetPack to 3.1. And I use the new JetPack and new L4T and I found it is very unfriendly in some functions. That's crazy NVIDIA.
after finishing flashing of os ip address of target cant be able to get
what to do???

In the instruction manual, for installing jetpack it says you need a "Serial cable plugged into the serial port J1A2 UART4 on the target connected to your Linux host directly or through a serial-to-USB converter. Required to setup serial console on the Linux host." How come it was not needed in your install here? Just trying to figure out if I have to go and buy another lead :)
I'm not sure what manual you are reading. This video is for the Jetson TX series. You appear to be describing the serial console on a Jetson TK1. In order to install JetPack In either case, a serial cable is not needed. The provided micro USB to USB cable is used to connect the Jetson to the PC host. Thanks for watching!
Hi, thanks for replying! Rightly or wrongly, its definitely in the TX2 manual - page 8 of this bad boy developer2.download.nvidia.com/embedded/L4T/r27_Release_v1.0/Docs/Jetson_X2_Developer_Kit_User_Guide.pdf?wEcgUYw92MxHVUUSkTBEcjkeHrKxywSn_ocU0Ns9TXPSVp9m8I0fxcCDqIEQOy4MCVcrj7KJBfPEooJsD4y3mysdiilbJ-zFiZKR27506Ygc3lIXcunV43zbE4-7dByeFDsIfSfkdJ_bgXzuBZBTaWLnaPq8rwR1vbIPTw8uZbBvmeRiKetN2A.
In any case, your method for getting it up and running worked, which is great! Sadly the readme in tegra_multimedia_api, at least in he version I got, no longer includes the code snippet, so I will have fun hunting for that! Happy jetsoning :)
Glad you got it to work!
Maybe the wording seems confusing to you. If you need to access the serial console, you need the J1A2 connected to the host via the serial to usb converter. Here's a video: ua-cam.com/video/eQCJy9iUvTA/v-deo.html
That's different than flashing the Jetson, as shown in this video.
For flashing, that page states:
"A USB Micro-B cable connecting the Jetson system to your Linux host for flashing."
The cable is included with the kit.
I tried installing Jetpack 3.2 on a host machine running Ubuntu 16.04.1 LTS, I received the following error: "Installing CUDA Toolkit 9.0 failed". The error said to check the cuda_host_9.0.log file which indicated I should run apt-get update, which I have done. This still did not fix the problem as the "Installing CUDA" pop-up warning came back. Any suggestions are greatly appreciated!
I do not have any experience with this issue. Please ask this question in the official NVIDIA Jetson TX2 forum, where a larger group of developers as well as NVIDIA engineers share their experience.
Can my host pc be running Ubuntu through a virtual box or will it not be able to connect to the programming cable? Only part I'm nervous about.

Missed the blue semi until it was about to smash us in the face :/ hehe
why cant we install the jetpack on the jetson itself and flash it directly?
It's a bootstrapping problem. This is an embedded system, it's somewhat difficult to program yourself when you're being overwritten. Thanks for watching!
After flashing, the keyboard & mouse don't work. Even the mouse doesn't seem get the eletricity (the mouse lamp is off). It all work before flashing. Anybody know? My setup are:
1. PC Host : Ubuntu 16.04 64bit
2. Jetson : Jetson TX2 Orbitty Carrier
3. JetPack : 3.3
The Orbitty is a different carrier board, which uses (at the minimum) a different device tree than the Jetson Development Kit. You should follow the manufacturer instructions provided for flashing your Jetson. ConnectTech has a video on the subject: ua-cam.com/video/9uMvXqhjxaQ/v-deo.html
Thanks a lot. I try to follow that video and finally it all works now.
Welcome. I'm glad you got it to work.

Hey, this was a great tutorial, I am apart of a robotics team at my school and we a attempting object or blob detection with opencv. I made it threw the whole installation process with no errors however when I attempt to run a sample it says permission denied. I'm no to sure why this is happing, but you readme file and my readme file are also possible because i installed the new JetPack 3.1. I ended up find the sample but not getting past the permissions problem. Any solutions?
Did you try running the sample with sudo?
Know it is tell me that my command isn't found. Just to make sure I am doing this correctly. Once I get pass this I feel like it will work however
1.Open Terminal
2.Enter file location/Call Directory
3.sudo "Enter"
4.Enter Pass
Also once the installation is complete dose the Jetson need the host machine anymore to function properly?
The Jetson is stand alone after it has been flashed.
Hi ..... JetsonHacks i hve got serious issue during my work on Jetson .. When i turn on my TX2 it starts by displying nvidia icon and after that it donot give any disply On jetson board 2 lights closed to the power button are on and one light left to the fan named (Alert PCI/SATA powered up) is on ..
I posted the issue in nvidia forum but i don't understand what to do know.. I seem that u are master of jetson tx2 so i am asking for help ... please help me about this issue and yhe red light which is on i-e Alert PCI/SATA powered up
The lights are as expected. More than likely you have an issue with the monitor. You should be using an HDMI monitor with an HDMI cable. For further debugging, use a serial console connected to your host machine. Thanks for watching!
thanks ..Jetson Hacks for replying... u are absolutely right . altough i am using HDMI monitor 16:9 with HDMI cable but i think the monitor is not well compatible with jetson .....what type of display you are recommending with jetson.?... i mean such monitor which donot create these issues..... again thanks for your reply..
I don't have any specific recommendations. You should try it on another monitor to see if it works.
okayyy

Hi, I tried the tutorial, it is very helpful, but I have a problem, I am not able to see anything on the Jetson display. Can you please help why I have this issue?
Thanks in Advance
It is difficult to determine the problem from your description. Do you have a HDMI monitor connected through an HDMI cable to the Jetson? Which Jetson are you using? Which version JetPack are you using?
JetsonHacks thanks for your response, I’m using Jetson tx2 and I’m using jetpack 3.0 and also the Jetson is connected to HDMI monitor through a cable
What type of monitor? Is it a HDMI Monitor?
It has DVI port. which I connected via HDMI-DVI cable
In general, that will not work on a Jetson. HDMI tells the Jetson how to configure the monitor driver, but the HDMI to DVI converter does not allow the Jetson to talk to the monitor and figure out how to configure it. You end up, as you know, with a blank screen. You will need a true HDMI monitor to work with the Jetson.
