Building firmware on Apple Silicone M1

[mortenhauan]

Hi

Trying to follow the instructions to build firmware on Apple M1 computer, but get this error when I run the cd mpy-cross && make clean && make && cd .. command:

> cd mpy-cross && make clean && make && cd ..
Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.
rm -f mpy-cross
rm -f mpy-cross.map
rm -rf build

make: *** [build/genhdr/qstr.i.last] Error 1
make: *** Deleting file `build/genhdr/qstr.i.last'

Also tried installing Ubuntu in Parallels, and there I get this error when running the same command:

../py/nativeglue.c:226:5: error: ‘nlr_push’ undeclared here (not in a function)
  226 |     nlr_push,
      |     ^~~~~~~~
make: *** [../py/mkrules.mk:47: build/py/nativeglue.o] Error 1

Has anyone else successfully build pycom firmware on arm computer?
