Hi Pablo

From the log it seems like something is wrong with the locale setup, since so many files there are reported as "No such file or directory". This could also explain why it works locally but not over the terminal in SSH. Check out this wiki page for more info on locales and how to fix the issue: https://wiki.archlinux.org/title/locale. It seems like the SSH client session is using sv_SE as the configured locale and that isn't enabled on the Pi. You can try something like "LANGUAGE=en nrfjprog -i" to test this.

Best regards,

Simon

Hi, I have added "export DISPLAY:=0" to the pi's bashrc and tried running the ssh with -X and -Y as suggested in the forum post you mention.

I have also run nrfjprog using strace, this is the output:

RE: nrfjprog not working on raspberry pi 4

Simonr — Thu, 28 Oct 2021 12:56:19 GMT

This sounds like a GUI application fails to start in the SSH text session.

export DISPLAY=:0 might help. See this forum post for example. We're able to run nrfjprog 10.14.0 amd64 over SSH on our side though. Perhaps running it with strace or some other debugging tool might give us a clue as to what's going on.

Best regards,

Simon

Same problem with nRF Command Line Tools v10.15.0. I haven't been able to try it other than over ssh.

$ nrfjprog -r --log
ERROR: [ Client] - Worker process is dead, cannot execute command.
ERROR: An internal error has occurred, please try again.

RE: nrfjprog not working on raspberry pi 4

Also, like I mentioned earlier installing pynrfjprog from the Github repo either through "pip install pynrfjprog" or "python setup.py install" doesn't install the armhf libraries on my RPi. So when I try to run a script using pynrfjprog I get an API error -
"NRFJPROG DLL: -150 NRFJPROG_SUB_DLL_NOT_FOUND. /usr/local/lib/python3.7/dist-packages/pynrfjprog-10.14.0-py3.7.egg/pynrfjprog/lib_armhf/libhighlevelnrfjprog.so"

I have raised this issue in the github repo as well

RE: nrfjprog not working on raspberry pi 4

Nikil Rao — Wed, 27 Oct 2021 09:32:52 GMT

The problem seems to be running the nrfjprog command if I access the RPi over SSH. If I connect a monitor and a keyboard to the RPi v10.14.0/v10.15.0 both work fine. If I access the RPi over SSH and try to use nrfjprog (both v10.14.0/v10.15.0) I get the "worker process is dead" error

RE: nrfjprog not working on raspberry pi 4

Simonr — Wed, 27 Oct 2021 08:53:39 GMT

Please try updating to nRF Command Line Tools v10.15.0 which was just released yesterday. Poor timing I'm afraid.

No,the .deb package doesn't install pynrfjprog, you have to download this wrapper from our GitHub.

Best regards,

Simon

RE: nrfjprog not working on raspberry pi 4

Nikil Rao — Tue, 26 Oct 2021 10:19:45 GMT

I can use nrfjprog commands now but there's still an error thrown when I use pynrfjprog

Does running the 10.14.0 .deb package also install pynrfjprog? I think there's also a bug in the latest pynrfjprog repo where the new armhf libraries are not installed even though they are present in the pynrfjprog/lib_armhf folder. I don't see the lib_armhf package included here - github.com/.../setup.py

RE: nrfjprog not working on raspberry pi 4

Nikil Rao — Tue, 26 Oct 2021 10:11:44 GMT

I switched from accessing the RPi over SSH and connected it to a monitor and keyboard and nrfjprog now works for some reason! Could there be any reason why it wouldn't work over SSH?

RE: nrfjprog not working on raspberry pi 4

Simonr — Tue, 26 Oct 2021 09:14:40 GMT

Hi again

No, I'm afraid we've not been able to reproduce it here. We have nRF command line tools 10.14.0 installed with the J-Link version you're using, and are not able to reproduce the issue. We can only assume something is off with the system setup on your end. Our recommendation is to update to the latest version of nRF command line tools using the .deb package and try again.

Best regards,

Simon

I can connect to the device with JLinkExe, but Issue with nrfjprog remains. Any hints ? Can you reproduce this on your end ? Simonr

RE: nrfjprog not working on raspberry pi 4

Simonr — Mon, 25 Oct 2021 12:27:33 GMT

Okay, it seems like this "missing library" might come from the Segger pop-up asking you to choose the emulator to connect to. I think this can be confirmed by running the J-Link configurator. Qt (which is the GUI library used by SEGGER AFAIK), needs the libsm6 shared library to show the pop-up. I think this is an issue with Segger not embedding their shared library in their distributable. Try adding this required package as well.

Best regards,

Simon

RE: nrfjprog not working on raspberry pi 4

picatostas — Mon, 25 Oct 2021 12:05:11 GMT

yeah, it is unrelated. Did you manage to use JLinkExe without nrfjprog ?

RE: nrfjprog not working on raspberry pi 4

Nikil Rao — Mon, 25 Oct 2021 12:03:07 GMT

@picatostas I think this is an unrelated error because you entered the wrong device name (nRF9160_xxAA should be the device name you use with JLinkExe) and if you had a GUI, JLink would have opened a dialog box with a list of device names. So you get the GUI library errors

RE: nrfjprog not working on raspberry pi 4

picatostas — Mon, 25 Oct 2021 10:50:39 GMT

Hi Simon,
installing that package drops a later dependency issue for "libXrender.so.1". I am currently operating the rpi over ssh without X forwarding, so I don't need the gui. Are those packages still required for using nrfjprog ?

RE: nrfjprog not working on raspberry pi 4

Simonr — Mon, 25 Oct 2021 10:40:29 GMT

It seems like there's a missing library here. (libSM.so.6). Have you instealled the libsm6 package? It can be done with the following command:

sudo apt install libsm6

We might have to add this package as a dependency if this occurs by default when using .deb packages for the tools.

Best regards,

Simon

It seems like the JLinkarm_nrf_worker is failing to start for some reason. This could be due to the execution privileges not being correctly applied, which makes the worker non-executable here. Can you check the access rights to jlinkarm_nrf_worker?

Best regards,
