I wish QEMU had better support for board emulation in general. I was hoping I would be able to do some kind of virtualization that could be ran for new members who have trouble setting up the IDEs. However, it turns out that our particular board and peripherals aren't well support :( QEMU only supports 3 Cortex-M4 boards iirc.

Yep, but at least it can do OS stuff, which it's REALLY GOOD FOR. (context: I tried like 3 times to make an os, failed, however qemu was having fun emulating my os, that's for sure)

So many thanks, i really appreciate your support for the community :)

Man, you are a perfect engineer, thanks for growing up my skills;)

I learned embedded rust on the xiao samd21 for 5 dollars a piece (they're actually stock now too!!!) - one of the benefits of arduino compatible boards with usb support is there's an arduino sketch to use a second one as a VERY cheap swd (serial wire debug) device.

I knew that something like that is not too hard to do, and in fact I even did a similar setup years ago to develop and debug some graphical UI for STM32, to get a quick and responsive debug and test loop that does not involve flashing the controller itself, but ran with an LCD emulator on the host. BUT you cannot underestimate how useful this is "built-in" to the project template. A low-friction qemu debug setup could be very useful in many more projects where you just wouldn't bother setting things up otherwise.

It's nice that you're zooming in on your editor and command windows. I see a lot of programming examples on KZread where I'm trying to watch on my phone and they have an enormous desktop with a tiny font and I can't see a thing.

If you are on IPhone (maybe android has it work too, but I don’t know if the android app supports it) if you do a reverse pinch your screen, you can zoom in to see it better (and pinch to zoom back out)

Learning embedded system without hardware? OMG You saved lots of poor people like me, thank you

Would be nice if you could intercept access to IO mapped memory in the VM and have some sort of interface to simulate the hardware.

Can you make a video on emulating RISC-V virt on QEMU? I want to work with RISC-V assembly but mostly doing Operating System stuff such as Memory Management, Scheduler, etc not any board.

Nice video😊 Only one little idea. In the end, when you froze the Programm via Port 3333, you first said "let's add in tcp://", but then removed it quickly afterwards without commentary, when the build crashed. I know editing is sometimes unnerving, but it would be better to cut out your mistakes entirely and redo the part. Gives the vid a better consistency😉 But overall a nice vid

Why the background music. Kinda distracting

How far can you actually go with these kinds of things btw? Could you "emulate" sensors for the embedded platform? I've experimented with some of these things a long time ago, back then I wasn't very knowledgeable and didn't get far, but if you do some things like that I'd really appreciate a video on it, and if you don't then a hint why this might be a horrible idea would also be great :).

Can you make video or a series about FreeRTOS?

I want to subscribe, but you have 66.6K subscribers. I can't mess that up for you.

man, would be cool, if show as your linux conf, I like how it's look like, but when try do same, I every time fail, so, I hope you see my comments and make this video, thanks)

You are supposed to use cargo-generate because that whole repo is a template. Don't change it manually

Cargo generate was super heavy in terms of dependencies so I skipped it and went to git.

@zaspanyflegmatyk2446

@@LowLevelLearning Yeah but cargo-generate is a tool that is installed on the system. So you install it once and that's it. You don't need to install it with every crate you want to make from a template. And from what I have seen the rust-embedded group provides quite a lot of templates for different projects so I very much encourage you to install it 😁

I followed this on 22.04 But there is nothing in the binary output when i inspect with objdump -d, ? Cargo run segfaults and qemu faults

Can you make same video for RUST on minimal RISCV emulator?

Is it a good idea to start embedded learning with Rust? The rust learning curve is so steep

Would be interesting to see how to use Rust for real board. Is it possible to use for ESP32? Thanks for your video, but it has not real use in life. QEMU very limited and no possible to see real GPIO tasks.

What will be if you will keep original main() and panic ? It is possible use it as 'normal' ? I mean looks a bit weird you disabled main and created your own. And panic can it just send some data trough USB/Serial with stacktrace or something meaningful ?

You'll be using features the compiler will not be able to use. You also have "nostd" on as a flag which means you couldn't get that functionality even if you wanted.

I recommend learning at least one assembly language first (doesn't matter which one)

I love rust. But rust does not offer any improvements for time being, it will improve in future I guess. Also if any argument against C is that it has memory safety. I ask the question why don't industry just optimize the compiler, why is there a need for switch in language, there are 2 problems here. 1. New embedded coders will have hard time deciding which lang to choose as we see in VLSI (verilog vs VHDL) and so many lang in software development. 2. Rust's compatibility with C. Engineers will have to rewrite all the previous drivers in rust. Imagine using STM32 but you have to rewrite new hardware drivers in C so that they are compatible with your old code in case industries switch to languages. I wish we had more compiler designers than coders & programmers

There are, like, 30 things that you did in this video, which all required a lot of background knowledge...so, interesting, looks cool, but far too much required for a "bare metal" kind of user Thx

Is it just me or is the rust Syntax super ugly?

Your explanation of semihosting is kind of lacking. Normally, semihosting means that a target can halt in a specific way; which tells the debugger (connected to a target through a debug probe) that the target wants to do something on the host - such as a printf. The debugger then gets the thing the target wants to run on the host from the target, and runs it on the host system, before possibly returning some value to the target and then resuming program flow of the target. It has nothing to do with emulation.

Thats a 5 dollar arduino..

I watched your embedded rust videos and honestly I'm not that excited about it. The whole point of using C for low level programming is easy access to memory, and rust makes this unnecessarily complicated.
