I am trying to flash STM32G431 (UFQFPN32 5x5)
Other STM devices like x103 are flashing just fine, but this one fails.
I even desoldered it from the actual project PCB, and hooked it up with the four SWD pins only, and still fail.
the main difference may me that it had a 24Mhz clock source, and then had ..nothing.
Is there any reason to believe that this chip needs anything more than SWDIO, SWCLK, and 3v3,GND to program? - (NRST is not connected)
..or maybe those are a bit more picky about wire lengths/firmware version etc?
