Cannot debug M0+ STM32WL55 in SBSFU Dual core project

Hi everyone, 

I try to debug CM0+ core (using GDB server) application LoRaWAN in SBSFU dual core project. If I only run the debugger on CM4, the program will start and run normally. But when I try to debug CM0+, it will not run and my program failed.
I have stopped CM4+ by breakpoint in time CM4 wait for CM0+ running, and not download the executable when debug CM0+. Anyone have experience with this?

Hello @TrungKien 

I suggest you to use the last version of STM32CubeIDE  and refer to the STM32 microcontroller debug toolbox - Application note part 9 for more details.

Best Regards.
