1. Identifying Development Kits and Serial Ports

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

    $ 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:

    $ 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 (see above) or dmesg:

$ sudo dmesg
...
[1198894.160703] usb 1-2.2: new full-speed USB device number 9 using uhci_hcd
[1198894.576542] usb 1-2.2: New USB device found, idVendor=1366, idProduct=1059, bcdDevice= 1.00
[1198894.576550] usb 1-2.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[1198894.576553] usb 1-2.2: Product: J-Link
[1198894.576564] usb 1-2.2: Manufacturer: SEGGER
[1198894.576567] usb 1-2.2: SerialNumber: 001050931892
[1198894.589375] cdc_acm 1-2.2:1.0: ttyACM0: USB ACM device
[1198894.596846] cdc_acm 1-2.2:1.2: ttyACM1: USB ACM device
...

Connect to the nRF9161 serial console using a terminal program on your Linux PC:

picocom -b 115200 /dev/ttyACM0

3. nRF5340-DK Serial Ports

Two USB ACM devices are detected by the Linux host when the nRF5340 DK is connected. They can be identified using nrfutil (see above) or dmesg:

$ sudo dmesg
...
[1199003.499651] usb 1-2.3: new full-speed USB device number 10 using uhci_hcd
[1199003.721099] usb 1-2.3: New USB device found, idVendor=1366, idProduct=1051, bcdDevice= 1.00
[1199003.721125] usb 1-2.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[1199003.721137] usb 1-2.3: Product: J-Link
[1199003.721146] usb 1-2.3: Manufacturer: SEGGER
[1199003.721154] usb 1-2.3: SerialNumber: 001050021575
[1199003.744604] cdc_acm 1-2.3:1.0: ttyACM2: USB ACM device
[1199003.752999] cdc_acm 1-2.3:1.2: ttyACM3: USB ACM device
...

Connect to the serial console of the nRF5340 application core using a terminal program on your Linux PC:

picocom -b 115200 /dev/ttyACM3

Connect to the serial console of the nRF5340 network core using a terminal program on your Linux PC:

picocom -b 115200 /dev/ttyACM2

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 v2.5.1-5-gb2bb1a280782 ***
[00:00:00.254,577] <inf> app: Start thingy9151lite_nrf9151_app v98.98-14-release on nrf9161dk_nrf9161
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 v2.5.1-5-gb2bb1a280782 ***
[00:00:00.251,098] <inf> app: Start thingy9151lite_nrf5340_cpuapp_app v98.98-14-release on nrf5340dk_nrf5340_cpuapp
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:

*** Booting nRF Connect SDK v2.5.1-5-gb2bb1a280782 ***
[00:00:00.000,701] <inf> app: Start thingy9151lite_nrf5340_cpunet_app v98.98-14-release on nrf5340dk_nrf5340_cpunet

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.

Also, some generic commands are supported:

uart:~$ kernel
kernel - Kernel commands
Subcommands:
  cycles     :Kernel cycles.
  reboot     :Reboot.
  stacks     :List threads stack usage.
  threads    :List kernel threads.
  version    :Kernel version.
  sleep      :ms
  log-level  :<module name> <severity (0-4)>
uart:~$ device
device - Device commands
Subcommands:
  list  :List configured devices
uart:~$
