hi
I am using STM32W108CB and made my own pcb. I've stlink v2 and want to use it as Serial Wire Debugger.
When I press 'connect to the target' in stlink utility I get message 'Internal command error'.
I've tried to search a lot but can't find what that error means.
I've not soldered crystal oscillator to the board yet. Does SWD needs the MCU with external clock?
I've triple check all the connection power supply. Each connection is perfect and well, don't know why SWD isn't working.
Any kind of help would be appreciated.
