ARDUINO_PORTENTA_H7

MicroPython version

git describe --dirty: v1.24.0-181-g495ce91ca; Building for ARDUINO_PORTENTA_H7.

But the board says MicroPython v1.25.0-preview.180.g495ce91ca on 2025-01-07; Arduino Portenta H7 with STM32H747 when I flash mpython (it already has mboot I guess).

I've also tried this for tag v1.24.0 and the same error occurs.

Reproduction

Following build instructions from here: https://github.com/micropython/micropython/tree/master/ports/stm32#build-instructions

git clone https://github.com/micropython/micropython.git
cd micropython/
make -C mpy-cross
cd ports/stm32/
make BOARD=ARDUINO_PORTENTA_H7 submodules
make BOARD=ARDUINO_PORTENTA_H7
make -C mboot BOARD=ARDUINO_PORTENTA_H7

Expected behaviour

mboot builds

Additional Information

With the help from Gemini i found a solution:

It seems like you're running into a build error. The compiler is reporting unknown type names like mp_uint_t and mp_int_t, which suggests a missing header file during the compilation of
emitinlinethumb.c. I'll start by examining the file py/emitinlinethumb.c to understand its dependencies.
╭──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮
│ ✓ ReadFile py/emitinlinethumb.c │
╰──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╯
✦ py/emitinlinethumb.c includes py/asmthumb.h and py/emit.h. The error stems from py/misc.h, which is included by py/asmthumb.h. I'll examine py/asmthumb.h now.
╭──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮
│ ✓ ReadFile py/asmthumb.h │
╰──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╯
✦ py/asmthumb.h includes py/misc.h and py/asmbase.h, but py/misc.h requires types from py/mpconfig.h which isn't included first. I'll check py/misc.h to confirm its dependencies.
╭──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮
│ ✓ ReadFile py/misc.h │
╰──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╯
✦ py/misc.h is missing mp_uint_t, mp_int_t, and NORETURN definitions because py/emitinlinethumb.c includes py/asmthumb.h before py/mpconfig.h. Other py/ headers include py/mpconfig.h first.
I'll add #include "py/mpconfig.h" to the top of py/asmthumb.h to fix this.
╭──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮

│ 30 #include <assert.h> │

After adding

to
