ESP-IDF Update to unblock Mac M1 Builds

[askpatrickw]

When installing the esp-idf from github and runing source ~/esp/esp-idf/export.sh it works but in a new terminal when running the export from ports/esp32s2/ I get ERROR: Platform Darwin-arm64 appears to be unsupported.

I can build successfully using the latest IDF (commit 73db142).

The fix in the IDF appears to be this one
espressif/esp-idf@5739127#diff-873391a19109de0fec9486d3ef26704a32fe81560a38f2e1f6c4f3db99d19350

Looks like it is time to update the IDF or possibly just pickup this one change.

I suggest switching to v4.3 branch. The v4.3 release is currently beta.

I'm ok if we switch to the 4.3 branch. I'm not planning on doing it myself. I'd expect them to backport this to 4.2 as well.

I started a PR and did the boring parts of updating the include paths. I don't know C so if someone is excited and could pick up from here, that would be great.

Im unable to build CP at all on M1 due to the inability to build mpy-cross from source in setting up my toolchain. Looked at the MicroPython solutions to this but not able to implement on the CircuitPython git sync - I know this detracts that the Espressif nature of this specific issue, but all the same stuck with this atm

If you can't build mpy-cross, then other things will not build as well. What is the error?

[wildestpixel]

its as follows in a clean case sensitive APFS case sensitive sparse image :

pixel@Andrews-Mac-mini circuitpython % make -C mpy-cross Use make V=1, make V=2 or set BUILD_VERBOSE similarly in your environment to increase build verbosity. ../py/persistentcode.c:419:2: error: mp_raw_code_save_file not implemented for this platform #error mp_raw_code_save_file not implemented for this platform ^ 1 error generated.

@wildestpixel Try changing line 399 in circuitpython/py/persistentcode.c to this:

#if defined(__i386__) || defined(__x86_64__) || defined(__unix__) || (defined(__APPLE__) && defined(__MACH__))

[wildestpixel]

Thats a big step in the right direction I just need to add a path export - mpy-cross is built, just the arm-eabi to link up :

/bin/sh: arm-none-eabi-gcc: command not found

Thanks so much :)

[wildestpixel]

ah - now at this :
pixel@Andrews-Mac-mini atmel-samd % make BOARD=circuitplayground_express Use make V=1, make V=2 or set BUILD_VERBOSE similarly in your environment to increase build verbosity. ../../py/gc.c: In function 'gc_sweep': ../../py/gc.c:298:68: error: 'MP_QSTR___del__' undeclared (first use in this function) 298 | mp_load_method_maybe(MP_OBJ_FROM_PTR(obj), MP_QSTR___del__, dest); | ^~~~~~~~~~~~~~~ ../../py/gc.c:298:68: note: each undeclared identifier is reported only once for each function it appears in make: *** [build-circuitplayground_express/py/gc.o] Error 1

After

export PATH=$PATH:/Applications/ARM/bin

[dhalbert]

Do a make clean BOARD=circuitplayground_express and then make BOARD=circuitplayground_express. The first failure may have messed up the QSTR generation.

If you are still having trouble let us know the arm-none-eabi-gcc --version.
