Hello everyone. I am working with nucleo-wl55jc1 (with stm32wl) and i have a problem. When i try to download a program in cortex m4 i can make it succesfully. But when i try to download a program in cortex m0+ , debugging is unsuccesful.

"Failed to start GDB server Error in initializing ST-LINK device. Reason: (4) No device found on target." Does anybody know? Thanks a lot!!
