4.2.7 config problem

Ender 5 pro, swapped board to 4.2.7, fitted CR touch, downloaded Marlin bugfix 2.0.x firmware and config examples, started to carry out modifications to firmware using VSC, everything good until choosing listed config for the 4.2.7 board, the board I have has a T5 sticker instead of marker pen code on the card cover ! my board has a STM32F103RET6 chip which is not listed in the config file, it only has RF type listed, I have spent hours searching for answers and trying to solve but no joy....can anyone help please ?

That doesn't make sense, I have no idea where or what your referring to with RF

In Configuration.h you set #define MOTHERBOARD BOARD_CREALITY_V427

If using Auto build marlin your presented with a menu

STM32F103RC_creality
STM32F103RC_creality_xfer
STM32F103RE_creality
STM32F103RE_creality_xfer
STM32F103RE_creality_maple

You click the one that matches your STM32F103RE with any options you may want

The T6 in the chip name is the plastic used around the chip and its temperature range, so it is not used in marlin.


If you not using auto build marlin you update platformio.ini
Set the line default_envs = mega2560 chnage it to = one of the environments listed above.
eg default_envs = STM32F103RE_creality


The T5 sticker means your board has TMC2225 so you should set driver type to TMC2208_STANDALONE
