1. Identifying Development Kits and Serial Ports

1. Usenrfutil to list all connected development kits, their serial numbers and associated serial ports:

   Code Block
   $ nrfutil device list 1050021575 product J-Link board version PCA10095 ports /dev/ttyACM2, vcom: 0 /dev/ttyACM3, vcom: 1 traits devkit, jlink, seggerUsb, serialPorts, usb 1050931892 product J-Link board version PCA10153 ports /dev/ttyACM0, vcom: 0 /dev/ttyACM1, vcom: 1 traits boardController, devkit, jlink, modem, seggerUsb, serialPorts, usb Found 2 supported device(s)

2. Use nrfutil to identify the specific devices:

   Code Block

   $ nrfutil device device-info --serial-number 1050931892 serial_number: 001050931892 boardVersion: PCA10153 deviceFamily: NRF91_FAMILY deviceVersion: NRF9161_xxAA_REV3 jlinkObFirmwareVersion: J-Link OB-nRF5340-NordicSemi compiled Apr 11 2024 17:44:26 protectionStatus: NRFDL_PROTECTION_STATUS_NONE $ nrfutil device device-info --serial-number 1050021575 serial_number: 001050021575 boardVersion: PCA10095 deviceFamily: NRF53_FAMILY deviceVersion: NRF5340_xxAA_ENGD jlinkObFirmwareVersion: J-Link OB-nRF5340-NordicSemi compiled Apr 11 2024 17:44:26 protectionStatus: NRFDL_PROTECTION_STATUS_NONE

2. nRF9161-DK Serial Ports

Two USB ACM devices are detected by the Linux host when the nRF9161 DK is connected. They can be identified using nrfutil or dmesg:

...

picocom -b 115200 /dev/ttyACM0

3. nRF5340-DK Serial Ports

Two USB ACM devices are detected by the Linux host when nRF5340 DK is connected:

...

picocom -b 115200 <vcom: 0 port>

4. Serial Console of the nRF9161

After the Thingy-9151-Lite application image is programmed to the target board, reset the board and observe the Zephyr banner and shell on the serial console:

*** Booting nRF Connect SDK v2.5.1-4-g0eb43b6d9219 ***
...
uart:~$

5. Serial Console of the nRF5340 Application Core

After the Thingy-9151-Lite application image is programmed to the target board, reset the board and observe the Zephyr banner and shell on the serial console:

*** Booting nRF Connect SDK v2.5.1-4-g0eb43b6d9219 ***
...
uart:~$

6. Serial Console of the nRF5340 Network Core

After the Thingy-9151-Lite application image is programmed to the target board, reset the board and observe the Zephyr banner on the serial console:

...

The nRF5340 Network Core application only provides logging output to the console, as the Zephyr shell is disabled in the project configuration.

7. Zephyr Shell

Most of the standard Zephyr shell features are available, such as auto-completion, command history, etc.
