Stuck at SD Card Update due to MCU Type mismatch

This should be your printerboard Sovol SV07 Plus STM32 Silent Mainboard with TMC 2209 Driver

I found the sources link for your printer here

In armbian-update.deb is a data.tar zipped.

In data.tar you’ll find the printer.cfg under .\home\mks\printer_data\config\

Good luck, hcet14
