I try to debug the mbed-os-example-mbed5-blinky program (I start with very simple thing !) and I have an error : STLink error (22). Then… nothing : every debug icons are grey.
I can build and upload to the board with success but if I click on debug, there is no upload.
Mbed Studio, ST-link drivers and firmware are up to date. The board is supported for debuging.
You can see messages on debug console on the pictures.
Do you have an idea ?
