mboot fails to build

Port, board and/or hardware

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

Observed behaviour

ports/stm32/mboot: Add missing include for irq.h

closedby IAmCoderopened 2018-11-21updated 2018-11-26

I was not able to build mboot. Received the following errors when building mboot for the PYB or STM32 boards, adding the include in the PR fixed it:

/ports/stm32/mboot$ make BOARD=PYBV11
Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.
