STM32VLDISCOVERY board debug problem (SYESTEM32)

Posted by swansorter on 2019-04-11 06:44

Dear sir,
I’m working with a board STM32VLDISCOVERY on a chip STM32F100RBT6

When connect the board and press the RUN button, a message is displayed:

“OpenOCD child process termination

Reason:

Unplugged target or STLink already in use or STLink USB driver not installed

Error: open failed (no matching adapter found)
