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

2nd flash the application firmware

I hope this helps,

Diego.

Hello,

We have simtrace v2. When we connect the device through USB to a laptop it does not respond. None of the lights turn on. It does not respond to any commands. ./simtrace2-lists shows Device = 0.

Can you give us some suggestions on how to use the device and if this is the normal behavior?

Thank you for your time.
