Impossible to see Nrf9160 DK on ChromeOs - Linux Debian

Gillen

Hello,

I have a debian installed on my Chrome OS. Everything seems to be ok on Programmer (launched from Nrf Connect for Desktop):

17:41:45.965
Using nrf-device-lib-js version: 0.4.13
17:41:45.966
Using nrf-device-lib version: 0.12.8
17:41:45.967
Using nrfjprog DLL version: 10.16.0
17:41:45.967
Using JLink version: JLink_V7.66a

When I try to select my device, I don't see it listed even though it's turned on.

What could be the cause ? 

Thanks !

    Hi, 

    Have you tried the latest JLink drivers from the segger website?

    Check first your board's connection to the PC. You could check if the board appears as connected to the COM port using something like Device Manager in Windows 10. Additionally, verify that the board is listed in the output of the command "nrfjprog --com". 

    Regards,
    Amanda

    The card is working correctly on a Windows 10 computer, it's on my Chrome OS with Linux developper mode that it is not shown. It appears in device management though. 

    Traduction of the french window on the left: 

    "Manage USB devices

    Authorize Linux applications to access to USB deveices. Once a device is disconnected, it is removed from Linux's memory. Only compatible devices are shown."

    The device is not showing on "Select device" menu : 

    Thanks !

    Hi, 

    Please provide the file log.log generated from running nfjprog --deviceversion --log.

    Hi Amanda,

    I have tried the command again, but the log.log generated is empty. I tried to remove the old one and entered nrfjprog --deviceversion --log to see if a new one is generated. It is but still empty.

    I managed to find another log file, located in my_home_folder/.config/nrfconnect/pc-nrfconnect-programmer/logs/2022-10-24T14_23_44.710Z-log.txt

    Here is what is inside :

    I hope it will help

    Hi, 

    That's from nrf-connect for desktop, not nrfjprog unfortunately. 

    The log.log exist under the executed path. Please check again.

    Hi,

    I checked indeed on my home path, where the nrfconnect-3.12.0-x86_64.appimage is executed from.

    log.log file exists, but never modified, and weights 0

    Thanks

    Hi, 

    Wherever you execute --log, the log.log would be under the path where you execute. For example, if you execute nfjprog --deviceversion --log under home, you should find log.log under home.
