Error when building on Linux aarch64

[sylvain101010]

Hello,

When trying to build on Linux aarch64 (Raspberry pi 4) I got the following error:

error: failed to run custom build command for `esp-idf-sys v0.20.0`

Caused by:
  process didn't exit successfully: `/home/ubuntu/rust-esp32-std-hello/target/debug/build/esp-idf-sys-791a8c4daff86dfa/build-script-build` (exit status: 1)

  --- stderr
  Error: Could not find the package with 'platformio/toolchain-xtensa32 @ ~2.80400.0' requirements for your system 'linux_aarch64'
  Error: No such file or directory (os error 2)

Then:

$ pio platform install espressif32
Platform Manager: espressif32 @ 3.3.2 is already installed
Tool Manager: toolchain-xtensa32 @ 2.50200.97 is already installed
Tool Manager: tool-esptoolpy @ 1.30100.210531 is already installed
The platform 'espressif32' has been successfully installed!
The rest of the packages will be installed later depending on your build environment.

So I successfully hacked my way by manually modifying platforms/espressif32/platform.py to require toolchain-xtensa32 @ 2.50200.97 instead of toolchain-xtensa32 @ 2.80400.0

But then I got the following error:

error: failed to run custom build command for `esp-idf-sys v0.20.0`

And can't find a solution for this error.

Any idea?

@skerkour I'm afraid that ESP-IDF Tools are not available for Linux - aarch64 - see this issue: espressif/esp-idf#6475

[sylvain101010]

@georgik Thank you!

Can we keep this issue open so future people with this problem will be able to found it easily?

Also I will try to hack my way around by compiling the toolchain myself or something so I may post my progress here.

[georgik]

Sure. It makes sense to keep it as open. I'll add it as discussion point for next community meeting: esp-rs/rust#80

@JurajSadel Steps:

• build Python Wheels for aarch64 and publish to dl.espressif.com/pypi
• verify status of publishing aarch64 toolchains from ESP-IDF (tools/tools.json)
• verify RISC-V and aarch64 for ESP32-C3 - compile https://github.com/espressif/rust-esp32-example
• build Rust Toolchain for aarch64 Linux - esp-rs/rust-build
• update installation scripts for Xtensa Rust toolchain

I installed the Rust tool-chain last night, as I saw their was an update. It was a fresh install on windows 11 running in a ubuntu docker container, as per the instructions. I understand the test-rust-toolchain.sh is not yet working for the version 4.3 as I am getting an error there. Also I haven't plugged the board in yet, but I noticed that file doesn't have the S3 target in there either. I'm pretty sure the version of IDF I have installed is 4.4 but its calling 4.3 I didn't notice that mentioned in the .sh file. Should I just disregard the test-rust-toolchain.sh? And just try build a project I have for arm64, with the esp32-s3 target? the ulp_gcc is working now, or is it still under development?
I received the s3 dev board, but Im in final stage of prototyping to send to FCC for certification, should I just stick to writing this in C for now, and wait for further development, as I need the ulp chip as part of the final code. Or can I just upload diffrent bin to another part of the flash rom with the C code? I have the main code .bin for the esp32, but the rest of the project is in rust... so before I go an rewrite all that I was wondering if that would even work << this part is off topic I know..

Hello @RepRapid!
ESP-IDF4.3 doesn't have needed patches yet. Currently, esp-idf-sys is always downloading new ESP-IDF even if you have installed one on your machine - here is opened PR for this.

The default ESP-IDF version that esp-idf-sys builds is 4.3.2. As a workaround, you can override the default version with the ESP_IDF_VERSION environment variable.
export ESP_IDF_VERSION=release/v4.4 and then clean build should work on aarch64 Linux.

At this moment, ULP coprocessor toolchain is not ready for aarch64 Linux, as mentioned here
