Hi,

(running Mac OS Mojave 10.14.5)

I can not debug my program, on stlink- gdb I get the following console message:

Also tried re-installing the stlink server and the IDE - got the same results.

What am I doing wrong?

Thanks!

After searching some more onto web, found a workaround that worked for me: erased the flash contents (using the open source stlink's st-flash utility) .

After that I managed to load and debug several times (using st-link GDB server, did not try openOCD).

Hope this helps someone :)

Attaching the GDB log file...

p.s. also tried re-installing the stlink server and the IDE - got the same results.
