That's an older version of nrfjprog, we're currently on v3.1.1.35916. Try installing the latest SDK (nrfjprog bundled with the installer).

Hi,

Doing a --pinreset should do the trick. However, I have never seen the error you're referring to before. Can you post the version number of nrfjprog? (nrfjprog --version)

Best regards Håkon

Hi,

Thank you for replying. Trying that command resulted in error: pin_reset_ignore_pall (return code 8) which is a strange error since i cannot find it anywhere on the internet.

In the meantime i rescued my prototype by trying recover command which seemed to have done the trick. So i did some more testing with the NRF_POWER->RESET register. Setting it to 1 seems to raise the power consumption from around 2mA to 4mA which is strange. Furthermore others than suggested toggling the reset pin to zero. From my understanding this is one of the progamming pins, but none of them helped lowering power consumption.

Thank you from your help

Hi Martin,

You should be able to exit debug mode by using nrfjprog's pinreset command (called from cmd.exe): nrfjprog --pinreset
