Unable to Access SWD on nRF52840

[WestCoastDaz]

Hi Dev Zone Team,

I have been working with the nRF series for quite sometime and I am having an issue with an nRF52840 based module that I haven't experienced before.  I debugging the nRF IC via SES and then closed that application and went to use ```nrfjprog``` to erase and put on production code.  I ran the ```nrfjprog``` command but the nRF8540 was no longer reachable via the debug port. The code on the micro is running fine as the device is functional.

I have tried updating to the latest version of ```nrfjprog``` and that didn't help.  I have included the log from ```nrfjprog```.  Is there any way to get access back to the debug port as the code running on the micro doesn't have a bootloader installed so it can't be updated.

Thanks,

Hi,

I don't believe I have a module with the new chip revision as I purchased these modules in 2021 and I haven't had to perform `--recover` operation with any of these modules.  That said I will try running this operation with the newer tools installed.  If that doesn't work is there anything else I can try?

Thanks,

[Vidar Berg]

Hi,

I see. But then I don't really understand why the debug interface becomes inaccessible. I would still suggest you try "nrfjprog --recover" to see if it might help.

The one thing that may "brick" the device is if you enable the DCDC regulator on a module which doesn't include the optional DCDC inductors. But the DCDC reg. is disabled by default in our nRF5 SDK examples, so it should not be on unless you have explicitly enabled it.
