Bug while using nRF-Command-Line-Tools_10_7_0(nrfjprog 10.7.0)

[bbslhb]

Hello:

    I am using nRF Connect v3.3.1 programmer to flash nRF9160 and got an error.

    

    Silk on nRF9160 is: nRF9160 SICA B0 191601

    Programmer can't recognize nRF9160 after error.

    I tried nrfjprog -e to erase but failed:

    

    I tried older nrfjprog and successed to erase the nRF9160:

    

    So is there a bug on nRFjprog_10_7_0?

Hello, 

I tested with v10.7.0, and had no issues. 

I have only one board connected to my computer. If you have more than one, please make sure to add -f / --family to ensure the correct board is selected.

Edit: I tested using nRF Connect for Desktop v3.3.1 - Programmer, and finished without any issues.

Kind regards,
Øyvind

GPS.hex

I used only one nRF9160DK to flash my nRF9160.

Can you please try to flash GPS.hex with Programmer? My Programmer version is v1.4.1

Issue will 100% happen when I flash GPS.hex with programmer v1.4.1

GPS.hex is based on NCS 1.2.0 and modem v1.1.1

My new nRF9160 chip silk is SICA B0 191601

My older nRF9160 chip is OK, no this issue.

Older nRF9160 silk is BAA-E 2.1.8 12147

I think the issue only happen on new nRF9160 chip.

I think the issue will accur more if the latest nRF9160 chip shiped to more customers.

So please verify the issue on nRF9160 SICA B0 191601.

I was able to reproduce the issue on my computer. Using the programmer app and the hex file you provided, the issue presented itself here as well. Trying to erase device with nrfjprog in the command line gave me the same error as you described. 

I was able to fix the issue with doing nrfjprog -f nrf91 -e, and updating the nrf connect for desktop app to 3.3.2. This will install latest Jlink driver 6.70.

Let me know how it goes.
