Ulab Issue compiling CircuitPython only with nRF Ports

[bobxor]

I'm using an M1 Mac for compiling, following the Markdown pages. I was successful in compiling the "/ports/atmel-samd" ports, specifically the "circuitplayground_express".

However, when I attempt to compile to any board within "/ports/nrf" I encounter an implicit declaration compiling error with ulab.

../../extmod/ulab/code/ndarray.c: In function 'ndarray_object_is_array_like':
../../extmod/ulab/code/ndarray.c:364:8: error: implicit declaration of function 'mp_obj_is_type'; did you mean 'mp_obj_is_true'? [-Werror=implicit-function-declaration]

I'll take any tips! Thanks!

What does your git status show? My guess is that your ulab submodule isn't synced up.

Thanks for the idea to look at my git. The issue was seemingly due to switching to the "6.3.x" branch, as I was following this guide:
https://learn.adafruit.com/building-circuitpython/build-circuitpython

I switched back to "main" branch and it now compiles successfully. Thanks!
