to try prevent people like us flashing it the manufacture will laser off the original marking and write new one but if the empty header is swd you can try...

you should read chip ID with pyocd and the board is 5v so be careful

please read wiki...

stlink v2 clone can all handle 5v if you want to use esp32 you need a series resistor 150R should be enough as the current does not exeed the 20ma...

on my stlink it cannot detect target so i assume it wont work your board actually is like the mm32 board using chip internal comparator for phase current i can...

check the ground and VDD connection, the gd32f130 32pin do not have ground???

yes true the mcu cost more then $1 probably so just get a new board to replace

Thanks for that information. That is really helpful.

Please re-open this so I can open a PR against this issue.
