I want to program the USERROW section with pyupdi. I tried the following command to set USERROW0 to 0x03:
pyupdi -c /dev/ttyUPDI -d avr128da32 -fs 48:0x3
48 should be the correct offset, it is the difference between the fuses (0x1050) and userrow(0x1080)
However, this always fails with:
Device info: {'family': 'AVR', 'nvm': 'P:2', 'ocd': 'D:1', 'osc': '3', 'device_id': '1E9709', 'device_rev': '1.7'}
Verify error for fuse 48, expected 0x03 read 0xFF
Error during processing
Any ideas what might be wrong?
