Hello, I have got a board with STM32F427II, instead of “classic” STM32F247VG. Difference is small - just more GPIO/ADC/SPI. So I thought that remaping of pins would make everything work, but I was wrong.
MCU Pins are here:
So I followed guide https://github.com/ArduPilot/ardupilot/tree/master/Tools/bootloaders
Created new bootloader and tried to build new firmware with changed pins. I sucessfully flashed bootloader - I can see new COM-port, MP can flash firmware. But I cant see new comport when main firmware is loaded.
I forked latest master and commit my changes to code here:
I had to add new alternate functions to some pins, unlocked some pins in chibios_hwdef.py script and created new hwdef.dat file.
You should see that I commented some power flag pins, are they important?
Thank in advance.
