Thingy:91X - flashing connectivity bridge with jlink reports error

[Achim Kraus]

I build the NCS 2.9.1 connectivity bridge with

west build -b thingy91x/nrf5340/cpuapp

when I try to flash that with jlink, I get

west flash

Achim Kraus Do you experience this issue only with the flashing with Jlink? Does it work if you use programmer app?

Sorry to write that:

You mean, the "programmer app" with the "bedeviled genuine check"?

I complained about that for years. In the past, so many people, including me, wasted so much time with that check, that I usually don't use the "programmer app" anymore now for a year. Using that "programmer app" with the "bedeviled genuine check" caused especially with the two MCU and the modem of the Thingy a lot of pain, if you want to update all. You frequently need to close and open it again, hopefully with everything in the right mode.

Therefore I would prefer to use west/nrfjlink to flash it, because that has worked in the past without that pain. And for now, it only fails with the communication bridge of the Thingy:91X.

Thanks for the feedback Achim, its good. 

UICR can only be erased with a recovery operation, so use "west flash --erase" or "west flash --recover" instead of just west flash. This might do the trick. 

https://hello-nrfcloud.github.io/firmware/html/troubleshooting.html here is a guide that might help. 


I advise to use nrfutil-device 2.7.14 as i know this works, there has been som minor issues in the latest versions.
