Debug ArchMaxV1.1

Hello. I’m investigating using PlatformIO.

I have ArchMax V1.1 .
I create a new project empty Mbed with the wizard …

I can upload the .bin into the board .

When i want debug this , i have the error :sleepy:

Failed to launch GDB: poioinit10 Error in sourced command file . Remote com error

Thank you a lot for your help …

Excuse for my english …

To enable SWD debug or to get debug message through USB Virtual serial, please install a driver from mbed.

See Arch Max v1.1 - Seeed Wiki

Could you provide a screenshot with all errors?
