We have an internal report for this issue already. I will bump it and link to this thread as well.

Hi, it installing it through pip does help though it would be good to take care of issue with native linux/windows version of nrfutil so people could avoid wasting a lot of time like I just did. Thank you for your help Jørgen Holmefjord

Hi,

Error 51 means that the file was not found:

$ nrfjprog --program code.hex
Parsing image file.
ERROR: The file specified could not be found.
$ $?
51: command not found

Could you try to install nrfutil through pip?

Best regards,
Jørgen

Hi,

thank you for your reply.

Yes, I did all operation with prebuild ncp.hex. I didn't build anything else other than dfu app.

Can you help me to find error codes for nrfjprog? Finding meaning of '51' error code could help in this case.

I checked multiple runs on newer 6.1.0 version windows/linux but it didn't work.

Only working solution is still v5.2.0 on Windows and it is no ideal either: I have to run it twice and when I want to close it, it usually crashes my cmd.exe window.

Hi,

Have you verified that the file (ncp.hex) is present in the path?

Did you download one of the prebuilt releases? I have only tested with nrfutil installed through pip, and I'm not able to reproduce this issue. I do however see a similar error when the chip is erased (verify failed with exit status 55). If I manually flash the ncp.hex file first, the nrfutil command works as expected, even with --flash_connectivity argument set.

Best regards,
Jørgen

I got some progress: second try using manually programmeg ncp succeeded. I lost a lot of my time because I didn't try twice I tried different methods instead.
