I've just run cargo build on the tip of development branch and I don't see any issues. That's with Rust 1.63 as well.

What branch / version you're trying to build?

michalfita commented 1 year ago

Try cargo update first.

cquick01 commented 1 year ago

Sorry for not including more info. Now seeing the same issue on 2 separate machines. Both Ubuntu 22.04 running under WSL2. Will try on bare metal.

Running off development. Just trying to follow the two commands in the README.

Thanks for any help

michalfita commented 1 year ago

Do you have Rust installed on the Windows host as well?

cquick01 commented 1 year ago

Nope, Rust is not installed on the Windows side. Does it need to be? Admittedly I am not nearly as experienced with Rust than say, Python... Thank you for your patience.

The steps I took (in Ubuntu under WSL) are as follows. Are there any dependencies or any other configurations/setup I may be missing?

  1. Install Rust with curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh, add source "$HOME/.cargo/env" to shell config and restart shell.
  2. Clone atsamx7x-rust
  3. Install the ARMv7-EM target: rustup target add thumbv7em-none-eabihf
  4. Build examples: cd boards/atsame70_xpro && cargo build --examples

I am also going to try building on a Manjaro laptop that I have laying around. I'll share those results soon.

Thanks again!

cquick01 commented 1 year ago

Unfortunately, getting the same error on Manjaro too... Was hoping WSL was the culprit somehow but that doesn't seem to be the case. I used the same steps as above to install Rust and everything.

cargo build actually does seem to pass, with just one warning (minor unused import), but of course doesn't produce the examples bins. But I can't get cargo build --examples working anywhere

error: could not compile `atsame70_xpro` due to previous error
michalfita commented 1 year ago

OK, I confirm the problem. However, the issue lies somewhere in dependencies, not our demo code. @tmplt do you know solution to this problem? BTW. CI doesn't seem to run full build only check, that's why this problem slipped there.

cquick01 commented 1 year ago

Diffing against the atsamv71 ones, looks like they are missing rtt_target::rtt_init_print!();. Adding these lines got the builds working

Now unfortunately I'm having trouble getting my same70 board to run these binaries so I can't actually test it, but that's a separate issue I'll have to work out.

michalfita commented 11 months ago

@cquick01 any progress since? Maybe you could PR the changes?

cquick01 commented 11 months ago

I was never able to get the binaries to run. Haven't really looked at it in a month or two.
