nrfjprog versions

[sakitten123]

I have an old version of nRFgo Studio and nrfjprog installed on my computer (version 5.2.0.45231). I use nrfjprog from command line to flash my devices (easier than clicking around in nRFgo Studio when flashing many in a row).

Now I have a new computer that I want to be able to use to flash my nRF51822 devices. I downloaded nRFgo Studio from the website, installed and tried to run my usual nrfjprog command. It didn't work. The version I got when downloading from the website was 7. something.

The command I tried to run was:

nrfjprog --snr <jlink_serial> --rbp ALL -e --program <softdevice_path> <application_path> --verify -r

The error message I got was something about "undefined command, run --help to....."

Then I tried to use mergehex to merge my softdevice and application to one .hex-file, and rerun the command above with just one path. Then I got another error message about combining commands that cannot be combined.

I can tell that the available commands are different when comparing the versions.

How do I adapt my command to the new version of nrfjprog? What have you changed and why?

Thanks!

for some reasons you cannot mix --program with --reset in the new versions. This should not have been changed in my opinion as it does not harm combining them and not allowing broke the compatibility. I have created an internal ticket for it and we would either get a good explanation or a fix for this. Until then split this into two commands, one for --program and one for --reset

I can understand that splitting this command adds overhead time for your mass production, but it should not be too bad. As I have created an internal ticket, it will be addressed for sure. I will not close this thread until then :)
