I need to check. Please use the following url in the meantime: https://github.com/NordicSemiconductor/pynrfjprog/releases/. It's available for download there.

And what about a solution using JLink software for ARM + pynrfjprog ? Or does pynrfjprog depend on nrfjprog binaries ?

I put this in as a feature request internally now, but please contact your regional sales manager if this is an important feature for you (send me a DM with your location if you don't know who that is).

September 2020, Segger announced support for ARM (https://www.segger.com/news/segger-j-link-adds-support-for-raspberry-pi-as-host). Can Nordic announcement for nrfjprog on ARM be coming soon?

Jlink commander works with UICR, but it doesn't have a dedicated command to erase it, so that has to be done "manually" by accessing the NVMC registers directly.

Jlink write commands to NVMC peripheral to erase UICR (note: w4 can be used to write to any part of memory, including UICR):

> w4 0x4001E504 2 /* NVMC->CONFIG= Een ( Enable erase) */

> w4 0x4001e514 1 /* NVMC->ERASEUICR = 1*/

You can find a complete command referecence for the Jlink commander at this page https://wiki.segger.com/J-Link_Commander.

I am interested in what you did Vidar. Thanks for the information.

Would that method be able to program the UICR ? Can it also erase the UICR ?

Thank you very much although I have one last question, in my case I used to flash with my Desktop with a script.bat, how can run this script from Jlink ?? I changed my script into script.sh but is it possible to run the script from Jlink ???

Thank you

You need to use the J-link commander program (named JLinkExe in jlink sw package) for programming. Nrfjprog is not supported on ARM.

Update: I just tested it on a Pi4 loading the blinky hex to a nRF52840 DK:

Thank you for your response, but I still have a problem with flashing. In fact I keep getting this error "test_script.sh: line 52: nrfjprog: command not found", it's like in my flashing script it doesn't recognize the cammand line tools. Is there a solution for this ?

Thak you.

Hi, the nrftools are all built for x86, but Segger is offering a ARM build of their J-link Software pack that you may be able to use: https://www.segger.com/downloads/jlink/#J-LinkSoftwareAndDocumentationPack. But notice their statement about this package not coming with any support.
