Hi, I experienced the same problem and Kevin Redon solved it. As per his words "The only cause I could find is an accidental short between the ERASE and nearby 3.3V pin (on top of the board)." And he was right. He documented the solution: 1st reflash the DFU bootloader https://osmocom.org/projects/simtrace2/wiki/Flashing#SAM-BA
2nd flash the application firmware https://osmocom.org/projects/simtrace2/wiki/Flashing#DFU I hope this helps, Diego.
