STM32: Not able to build mboot without USB and user switch

port-stm32

I'm trying to do a board without a USB or switch, using the STM32F411. I want to use MBOOT to update the FW only when it is called from within an application so have no need for a USB or switch. It will use an external SPI flash chip. I've got this working on the basic pyboard.

I've declared the below - yet MBOOT gives multiple errors when calling sudo make BOARD=NAME__ USE_MBOOT=1 clean all

#define MICROPY_HW_HAS_SWITCH (0)
#define MICROPY_HW_ENABLE_USB (0)
#define MICROPY_HW_USB_FS (0)

Is there a way to use MBOOT without a USB or switch?

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
