I need to run the serial terminal on ubuntu22.

I can see my device in the list when click the select device dropbox. But when I click connect, I have an error:

nrf-udev and jlink has been istalled

Thanks for your help

Hi, 

Could you make sure the port and the device support the serious terminal?

Could you check if the serious port is not used by other applications as the log indicated?

Could you provide the log file from the "OPEN LOG FILE"?  

Regards,
Amanda H.

I fixed the issue that  this is actually a permission problem u have to allow your serial terminal to access the specified port just simply type following commands in your terminal

sudo su
//type your password
cd /
cd dev
chown username ttyUSB0
