STM32CubeIDE unable to debug. Error in final launch sequence, error launching GDB server
So, I am learning stm32 mcus, using a nucleo f4 board.
Everything was working fine and now debug launch fails.
Actually, I was doing one debug, closed it and next debug session won't launch.
Atollic TrueSTUDIO does work with the same settings (st-link gdb server in the debugger settings).
CubeIDE works in linux.
