Bootloader will not build

[SvenHaedrich]

I tried to follow the build instructions for the multi-bootloader.. I follow the instructions in the README.md. Nevertheless, the build fails with:

[100%] Linking CXX executable PicoMite.elf
/usr/lib/gcc/arm-none-eabi/13.2.1/../../../arm-none-eabi/bin/ld: CMakeFiles/PicoMite.dir/External.c.o: in function `cmd_port':

make: *** [Makefile:91: all] Error 2

This leaves me puzzeled. The following would be nice:

• include the pico-sdk in the project. It would nice to pin the version.
• pin the pico toolchain version
• for me, the build had warnings

In this multi-bootloader
we use madcock's PicoMite
so we need a little patch for pico-sdk as the picomite's repo says

https://github.com/madcock/PicoMiteAllVersions?tab=readme-ov-file#setup-picocalc-firmware

mkdir -p ~/picocalc && cd ~/picocalc
git clone https://github.com/madcock/PicoMiteAllVersions.git
cd PicoMiteAllVersions
mv ~/pico/pico-sdk/src/rp2_common/hardware_gpio/gpio.c ~/pico/pico-sdk/src/rp2_common/hardware_gpio/gpio.bak
ln -s ~/picocalc/PicoMiteAllVersions/gpio.c ~/pico/pico-sdk/src/rp2_common/hardware_gpio/gpio.c
mv ~/pico/pico-sdk/src/rp2_common/hardware_gpio/include/hardware/gpio.h ~/pico/pico-sdk/src/rp2_common/hardware_gpio/include/hardware/gpio.bak
ln -s ~/picocalc/PicoMiteAllVersions/gpio.h ~/pico/pico-sdk/src/rp2_common/hardware_gpio/include/hardware/gpio.h

btw
this multi-bootloader is kind of out-of-date , people from CPI forum created a better way,without re-compiling every uf2

I wil try to catch up later if I got spare time
