Hello everyone,
I work with an Arduino mkrzero board. I use the Atmel-ice programmer. The upload via Microchip Studio via swd works with it.
When I do an upload via PlatformIO and the same HW, it does not work!
I have defined the programmer and the protocol in the PIO.ini:
debug_tool = atmel-ice
upload_protocol = atmel-ice
The terminal output is:
Building in release mode

Does anyone have an idea what the problem could be?
