Creality 4.2.2 stm32f103ret6 support

[macmimy]

I have a bunch of Creality 4.2.2 stm32f103ret6 boards from upgrading ender 3v2's I'm sure I'm not alone, was wondering if its possible to get grblhal on them they seem similar to the blue pill. I found schematics for it Jyers/Marlin#814 , I'm assuming a pin remap wouldn't be all that is needed ?

It is all that is needed for basic functionality as the Trinamic drivers are not controlled by code, you can make one?
Note that native USB is not supported - #define USB_SERIAL_CDC 1 has to be commented out in my_machine.h

There is an EEPROM on the board but according to the scematic is not connected to I2C capable pins, if this is to be used code has to be added to bit-bang the I2C protocol.

I am in the same situation- any update/progress in this?

I have just ported to the Creality 4.2.7 board and successfully run it in coreXY. I have a bit more testing to do, but i'd be happy to upload it.
