Hi Kaja,

I have verified this issue has been resolved. Turns out it was a grounding issue with the hardware causing instability in the nRF chip. I am glad the team was still able to find a bug and hopefully it helps others who may be experiencing something else.

Thank you for your support.

Chris

Hi,

turns out that there is a bug in the programmer app, which seems to have been introduced in the last update. The team is currently working on a fix. In the meantime, I recommend you use nrfjprog for programming.

nrfjprog a command line tool we have for programming over Jlink and can be downloaded at https://www.nordicsemi.com/Products/Development-tools/nrf-command-line-tools/download.

Programming with nrfjprog:

$ nrfjprog --program nrf9160dk_asset_tracker_v2_2022-12-08_188a1603.hex --chiperase --verify --reset

Sorry for the inconvenience.

Best regards,
Kaja

Hi Chris,

the bricked ZIP's they worked before with and older version of the MFW?

Have you gotten a HW review?

Best regards,
Kaja

Okay upon further analysis, I do not believe this is caused by firmware 1.3.4 as this also happened on the firmware 1.3.2 board as well.
