I recently purchased a Creality 4.2.7 with an STM32F103 microchip from AliExpress to replace my fried Sovol SV06 motherboard. Because the layout was very similar to both the BTT SKR Mini E3 V3 and the stock Sovol motherboard, I assumed the replacement would be easy and that I would save a few bucks instead of buying either of those. I was mistaken and finding the correct pinouts and Klipper configurations are much harder than I thought. I stumbled upon a full electrical schematic of the board and this did have the pinouts, although difficult to read. I entered all of them into my printer.cfg but I'm of course still having trouble.
After changing the TMC motor drivers to the TMC2208 (TMC2225 are very similar) I get Option 'uart_address' in section 'tmc2208 stepper_y' must have a maximum of 0 which doesn't make sense to me and after changing it, it still refuses to work. I'm hoping someone more knowledgable than me can spot a mistake I made and it'll be a easy fix.
