I show Interrupt handling in tree videos I did for DMA-interrupt1;2;3. For circular mode you first need to do the Scatter Gather mode. This mode have cyclic option I may do a tutorial on it in the future.

I attached my GitHub

Thanks for your comment you shouldn't be afraid from the Vivado. I'm taking you step by step of building the Design. I found an XSA file here forum.digilent.com/topic/19157-vitis-hw-platform-in-arty7-20/ but I'm not shore which version of Vivado was used, and it is very important to much the Vivado version with the Ubuntu version and the PetaLinux version. Thanks Udi

Thank you for your comment. I plan to make more video like this in the future, and I hope you'll find them useful.

​@@Udi-FPGAcan you please make a video on zynq ultrascale+ mpsoc.

@@gnanapradeep2933 I wish I Could I need an zynq ultrascale+ mpsoc at home for this. (I'm doing my Videos at home) but I work with mpsoc at work and it is exactly the same. just that the mpsoc have 6 cores and the zynq7000 only 2. once you put your zynq in the Block design and add something (like DMA) the Autoconnection will work the same.

Hi Dong Thank you for your nice comment. I did those tutorials to help you and other like you. For your question: I can thing of two options why the Linux askes for user and password. I saw Linux distributions which asked this and the user's name & password were 'root'. (User-name: root and password: root). But as you can see in my videos this wasn't the case when I installed my Linux. Another option is that you forgot to add boot.scr file to your SD-card. This happened to me in the first times I did this. This file is a new addition to the Xilinx Petalinux and wasn't in previous versions of Vivado/Vitis/Petalinux. I hope this is useful to you, and again thank you for your comment.

@@Udi-FPGA Hi Udi, Thank you for your prompt reply. I did add the scr file into SDcard and also tried root:root as username:password but none of them works. it is weird, isn't it?

@@Udi-FPGA Dear Udi, i found the reason for my problem. I used petalinux 2022.1 and and for the first time, I have to enter the petelinux as username, then it will ask me to set a new password. cheers! Dong

@@DongNguyen-qq3in Hi Dong I’m glad you succeeded in working this out. I say many times in the tutorial to keep Vitis/Vivado & Petalinux in the same version. In the first video you can see that I go to a lot of troubles to match the Ubuntu version to the Vitis/Vivado/PetaLinux version. Good for you and have the best luck. 👍

This problem is from ASIC design. When designing an ASIC, we use to prototype the ASIC on FPGA, until the ASIC is ready (which an be a year or more from now). For that we start implementing the Verilog code on an FPGA, check it in high speed and even write software for the ASIC which will be here a year or more from now. Most of the Verilog code for the ASIC is peripherals. The ASIC CPU can a third-party CPU (like ARM or ARC) but we develop the peripherals, so I don't need the real CPU we just need a CPU which can do reads & writes from the code. The Nios II do this nicely if we just have a comfortable bridge. And this is what, I was trying to show in this video.
