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,

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.

Hi,

I tried to execute the command on different folders, but the same behavior is happening : a log.log file is generated, but not modified and weights 0 oct.

Hi, 

Could you try specifying the log file directly?

"nrfjprog --deviceversion --log ~/nrfjprog_log.log" for example.

Hello again, and sorry for taking so long to reply.

I have tried as you said by specifying the log file directly. It creates a log file but same case as previously, it weights 0 and is empty.
