Please, give me the bootloader Ender 3 v4.2.2
I changed controller STM32F103ret6. I use it for writing firmware.
I have Programmator st-link v3

this method doesn’t work. I repeat once again, I replaced the controller microcircuit with a new one on the board. how should a new controller understand that it needs to load firmware from sd? first you need to let him know how to work. I tried to program the firmware using the programmer, this method also does not work, the firmware is installed, but without the bootloader, the controller does not understand what to do with it.

@jenik6 Sorry I have no idea about it. You need to ask the hardware engineer, it goes beyond printers.
