I’m trying to upload some code to a RP2040 pico, using the current ArduinoMbed framework. The debug probe is the original Raspberry Pi Debug Probe.
Uploading via picotool works, but fails when the code is stuck in a hardfault, then a reset a bootsel is necessary. Now I want to use the debug probe and have changed my platformio.ini to:
[env:pico] platform = raspberrypi board = pico framework = arduino upload_protocol = cmsis-dap debug_speed = 5000
The cmsis-dap is found, but it fails with:

is there some setting missing?
