Very helpful, thank you! The fact that you were able to do this so smoothly live is really impressive

the Broadcom GPU is the bane of my existence

Would it be too complicated to use a baremetal approach to make an OTA of firmware, such as the micopython firmware?

zero to window would be without wayland-client...

Liked and subscribed. I'm going to go back and watch all your bare metal videos on the RPi Zero and Pico!! I hope you return to make more videos.

exactly what i just searched for on google, can't believe that it actually could come up with a result this good

A bit reckless imo with the ring counter oscillator overclocking. I am convinced you can do much better. Keep up the good work. Thank you otherwise for great instruction. I'll be lurking if it matters.

It is a shame that there is no assembly editor like asm-one was back then in good old Amiga times… coding never been so much fun in any ide since then. 30 yrs later all we have msdos-like ugly windows and that’s all. Kinda frustrating. Anyway it is a great idea to make an asm series for the pico. But I disagree in terms of thumb mode superiority. I think in thumb mode you don’t have the those conditional commands like the movne addle and so on which was a killer feature. We coded ppc in asm back in early 2000’s and then we made a nintendo gba demo for a competiton in arm asm. (We used goldroad assembly which was pretty cool and we used sublime text for editor and we added the python script which did the build to the f1 key. It was a more sophysticated way but far from the asm-one..) and those commands of the arm oh boy that was a game changer. We succeded to make the code almost without a single branching by using those conditional commands. Arm has the best assembly imho.

NMI is not "nested mask interrupt" it is Non Maskable Interrupt. A vector is a quantity with direction and length which indicates a destination's position from an origin. If you don't understand what a vector is , that may explain why you think it is not a good name. I don't get the feeling you are in a position to teach this subject. I'm outta here.

idk if wayland is the way to go there are still so many applications where wayland cant handle them nativly and need to go through XWayland I think xcb is still the way to go

One problem is this: it becomes progressively impossible to understand how the linux works by inspecting the source code.. cleanup is really necessary.

cannot agree more.. linux source code must be cleaned..

I need to run a c# Desktop application using weston on ubuntu??

Hey can you tell how you got kernel image? i have been trying to get this to work but can't seem to figure out how to convert the .s file to .img @willth8

Excellent! Thank you.

Thanks for sharing. Have not worked in assembly since the 80’s. Beings back fond memories.

Great explanation, but your volume is a little low.

cant hear or see

What is your IDE name ?

Gigahert. You're so cute. Anyway, cool stuff. Assembly looks like a real ballache. All those registers. God bless.

Hello, nice video. I believe that you built you kernel image yourself, containing your binary ? Can you explain how you do that, since you made a loop in your program, did you just compiled you ASM program into an ELF and renamed it kernel.img ?

Thank you so much! This will come in handy in the future when I'll try to build my own GUI library! Please, consider updating in 2-3 years, in case Wayland changes its architecture!

Props for making this series. It's unfortunate you aren't using the toolchain people will probably want to use for this. NiH is great for learning, but not great for a tutorials for a general audience.

amazing video

I would love to see you using dual core

I'm the thousandth subscriber!

how are you theming your setup???

HI! can you explain exactly which IDE do you use for programming in assembly language? (and all tools for loading of internal SRAM memory) DO you use SWD picoprobe or SWD DEBUG PROBE? (for loading internal SRAM) DO you have possibility of debug your program - step by step in internal SRAM? (sorry for my very weak english)

Are you using external libs like wlroots?

Really good tutorial, looking forward for more wayland tutorials from you

80 minutes for a barely functional window 😂 Wayland is a joke!

Your color scheme makes it hard to read your code (#include is near invisible).

can relate too much @ 29:08

f* callback hell

I have a dso with a frequency of 100 MHz, and I use Thonny IDE and Micro Python with a Rp2040 system clock of 125 MHz. I also know the pwm frequency, which is 62.5 MHz. I have to make a pwm in an RP2040 at 25 MHz in PIO, thus here's my code: import machine import utime import rp2 # Define the PIO program for PWM @rp2.asm_pio(set_init=rp2.PIO.OUT_LOW) def pwm_prog(): wrap_target() set(pins, 1) [1] set(pins, 0) [1] wrap() # Create a PIO state machine with the PWM program sm = rp2.StateMachine(0, pwm_prog, freq=25_000_000, set_base=machine.Pin(0)) sm.active(1) I want a square wave, however the PWM produced noises and ripples with this code. And I want to use this method in PIO Thus, how can I lessen the noise and ripples? Help me please sir

the thing people still do not seem to understand is, that "wayland" actually does nothing. it does not exist, it is not a piece of software. its a specification, and just that. wayland describes how you talk to _A_ compositor, it is not one of on its own. its just the description of an api. basically the complete introduction of this video is factually wrong.

Excellent tutorial! I lost it every time you yelled f**k when the compiler complained

"How to set a variable in the time it takes you to write an entire application in C"

6:36 "It is never a waste of time to deepen your understanding." Amen, brother. _Amen_.

Your vids are great, hope you still have some inspiration to do more. They're being viewed and thought about. And no cringe re systemd.

Worked through it, highly recommend. Great walkthrough. I hope others find this, it should be linked in the fd.o docs along with the book. Nice work! Thank you.

This is so refreshing to hear. I think a lot of this is innate, you either have that burning curiosity and passion or you don’t. When I listen to your tutorials, I feel like I’m accessing something rare and powerful, unlike a lot of the over produced crap out there. Please make more low level videos

@12:38 - I had to look that up. lsl = Logical Shift Left (immediate) shifts a register value left by an immediate number of bits, shifting in zeros, and writes the result to the destination register.

❤

I am more impressed with your ability at mental math in bit-shifting and such, than anything else. Would love a video on the techniques you use.

I've tried to start an OS on the B+ it was somewhat simple with fasmarm, the documentation is horrible. I have gotten as far as getting text on the screen, and typing with a ps/2 keyboard (sure as hell not figuring out the usb standard lol) it was fun, i wish i continued it. I guess i burned out. wish there were more devices like this with the intention of baremetal in mind. guess i wanted to make a cluster of raspberry pis and have them each running different parts of my OS. too much for one person though lol. but it was fun while it lasted. I feel like arm is great for learning though, and their new documentation is pretty nice.

It's funny, as bad as X11 is, somehow Wayland's API manages to be 10x more incomprehensible. An hour and 20 mins to set up a not even a fully featured window is ridiculous. The state of programming is depressing.

Why don't you have your editor and pdf on the same screen instead of constantly switching back and forth?
