Hi,
I'm struggle with similar problem to connect i2c sensor to expansion board Duet3HC.
Could you publish your fork on github?
Thanks in advance
@dc42 It worked after updating ICE's firmware. Found out that atmel-ice firmware version was same. And again tried to flash bootloader it got failed with same error. Then again updated the atmel-ice firmware it worked. There is problem with ICE. Thanks
