  After --recover the firmware seemed to work only in the jig, not with a battery. So I tried memwr and then it worked fine. Maybe someone could verify if this step is needed.

  I can confirm that this works:

  1. Solder P0.21 and connect to VDD in programming jig
     
  2. Run nrfjprog -f NRF52 --recover
     
  3. Flash firmware without CONFIG_GPIO_AS_PINRESET defined (look in *.emProject and remove)
     
  4. Run nrfjprog -f NRF52 --memwr 0x10001200 --val 0x00000015

  Hello,
  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:

  FUNCTION: recover.
  InitTarget() start
  InitTarget() end
  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?

  Thanks
  Adam

  Hi Gordon,
  I added MCUBoot and it does stop at a breakpoint in main.c now.

  Hello,
  I am trying to flash blinky sample from Nordic SDK into my puckjs v2 via SWD.
  I have tried both Segger and PlatformIO. The download seems to be successful but when I run it in debug it stops executing in reset.S line: bl z_platform_init.

  Do I need to modify the sample code in any way to run it in puckjs?

  Thanks

  Web IDE in Windows10 Chrome. I tried nRF iOS and it can see the device as DfuTarg when the green light is on but then fails to update (connection timeout in log)
