I am trying to flash puckjs via a programming jig from Espruino shop and with NRF 52832 DK and Segger Studio. I managed to load a simple LED sample into my puck v1.0 but my other puck v2.0 stopped working after erasing and flashing the same software (no SoftDevice, using Segger). I tried nrfjprog --recover but the log shows now:
Found SW-DP with ID 0x2BA01477
Failed to power up DAP
Before erasing I was able to see boot+softdev+app in NRF Go Studio.
Is there another step I need to do before I can erase and load my own firmware?
Can I still recover this puck?
