Hello,
I power the DWM1001 chip with 3.3V output from arduino on a breadboard, it works fine. But afterwards, I unplug the DWM1001 from the breadboard directly instead of turning off the arduino, which now I realize might cause some voltage spike on the chip. Then, the chip is not working anymore. Connecting with J-link Commander I get this log:

My question is, is this chip burnt? Are there any chances I can bring it back to life?
Thanks.
