Intro
We are using the nRF9160 with sensors we manufacture. The code developed is based on the serial SLM sample, toolchain v1.6.0. I am trying to keep the code/project files the same.
nRF Connect v5.0.2
Programmer v4.4.2
Tool Chain v1.6.0
Windows 10 Pro workstation.
Visual Code IDE.
Problem Source:
I opened nRF desktop on my development station and when prompted to "upgrade" I made the mistake of clicking YES. The upgrade was from v5.0.2 to the latest. New Segger software was installed and since then I cannot program any of our nRF9160 products. The nRF Programmer reads the device and shows "unknown_family". On occasion it will read Device version NRF9160_xxAA_REV2. Trying to program, erase or reset the device, will cause the error message below.
Error Message
With the new version I got "Error: Failed with exit code 1. No devices with requested serial number(s) or trait(s) found.".
Second PC
The update changed the firmware in the J-Link. I tried using the J-Link on a production PC and got the same error.
Attempted Fixes over 2 days:
1. I uninstalled all Segger and nRF software
2. Installed nRF Connect version v5.0.2.
3. rebooted.
4. replaced the firmware in the segger J-Link, using JLinkConfig.exe. The J-Link now works on a second station, but not on my PC.
5. repeated step 1, 3 above, removed all nRF drivers using pnputil.exe -f -d oemX.inf
6. Repeat step 5, using different Segger software versions.
