It's probably not a configuration issue. It looks like everything is in place to perform the unlock. Beyond that, for the time being I'll have to defer to the author of the nRF91 family. cc @maxd-nordic
I'd like three things for debugging:
@maxd-nordic:
Unlocking works with Segger's J-Link, but this one indeed has the nRST line. I was trying to find a less costly alternative for the devices on CI.
Thank you for the support!
For this version of the nRF91, you can unlock it and then try reconnecting after a power cycle.
I see - maybe pin reset support could be hacked into this by using a stray testpoint and modifying picoprobe. This definitely works with some other custom CMSIS-DAP probes. Other than the missing pin-reset support, this probe is really neat, I didn't know that one before.
Thank you @maxd-nordic,
It looks like debug probe's GPIO 0 is connected to nRST. I tried, but didn't get any luck so far. Indeed the power cycle does the job :) ! Maybe some information to add to documentation of the class.
Great support!
Thanks @maxd-nordic! I can add some docs about this to the target family usage notes.
I'll also add some notes about the Raspberry Pi Debug Probe.
Hi,
Unlocking the nRF91 seems to fail on pyocd 0.35.1 (Windows11, python 3.11.1):
