@reivilo no I am a private person. I don’t represent a company as such…
I therefore have no programmer-debugger like a Segger J-Link at my disposal.
I somewhere read that maybe by loading a new bootloader into the Xiao, like the CircuitPython bootloader and than the normal one again, that the problem might be solved…
I am going to try this maybe tomorrow.
