(IDF 5.0.2) ESP32S2 apa106.py compile error

[fcolmant]

Hello,

I'm working on macOS 14.0 / IDF 5.0.2.

When I do compile v21 of Micropython for ESP32S2 (or for ESP32), I do get this error :

MPY apa106.py
error compiling apa106.py:

ninja: build stopped: subcommand failed.

If I get rid of the apa106.py file, the compilation gets stuck at :

MPY flashbdev.py
error compiling flashbdev.py:

ninja: build stopped: subcommand failed.

The specific steps I do take are :

git clone https://github.com/_user-name_/micropython
cd micropython
git remote add upstream https://github.com/micropython/micropython
git checkout -b dev-branch
cd mpy-cross
make
cd ../ports/esp32 
make BOARD=ESP32_GENERIC_S2 submodules
make BOARD=ESP32_GENERIC_S2

It's the second time I try to compile Micropython. The first time was a year or 2 ago, and it went flawlessly. This time I really don't know what to do.

Any help would be appreciated.

Cheers,

François.

This file 'only' import neopixel.. and is inside ports/esp32/modules
Perharps do a 'make clean' before
if not there is pb in import neopixel

Did you find a solution to this?

It may be that mpy-cross is missing. Did you build it before?

I suggest to give mpbuild a try as that removes the hassle of setting up the toolchain and the correct IDFs.
you need to have docker (or similar) running, and the MicroPython repo cloned;
then from the repo run:

mpbuild clean ESP32_GENERIC_S2 # to clear out old partial builds 
mpbuild build ESP32_GENERIC_S2

If you need a specific IDF version , then you can try that after you have your first successful 'default' build

@robert-hh I have mpy-cross built, @Josverl I am using a custom board so I can't use a generic one

Here is my build output:

This is the repo that is being built:

Note I am building this on Macbook Pro M1
