Error when writing with J-Link

Junichi

If you try to write a program on a board with nRF5340 installed, an error will occur.

I can write to other boards using the same J-Link, so I don't think it's a J-Link problem.

When writing with VSCODE, the following error is displayed.

-- west flash: using runner nrfjprog
-- runners.nrfjprog: Flashing file: c:\Users\TSP_M1\nrf5340_audio_demo6\build\zephyr\zephyr.hex
[error] [Client] - Encountered error -12: Command select_coprocessor executed for 30 milliseconds with result -12
ERROR: Failed when selecting coprocessor APPLICATION
[error] [Worker] - Low voltage 0 detected in target device.
ERROR: Low voltage detected at the target. Please make sure the device is
ERROR: properly supplied.
NOTE: For additional output, try running again with logging enabled (--log).
NOTE: Any generated log error messages will be displayed.
FATAL ERROR: command exited with status 43: nrfjprog --program 'c:\Users\TSP_M1\nrf5340_audio_demo6\build\zephyr\zephyr.hex' --sectorerase --verify -f NRF53 --coprocessor CP_APPLICATION --snr 821007475

Add --log and attach the generated log.log file.

Please tell me the cause of the error.

    Hi,

     

    ERROR: Low voltage detected at the target. Please make sure the device is
    ERROR: properly supplied.

    Have you checked if there's an issue with your power supply?

     

    Kind regards,

    Håkon Thank you.

    I made a mistake in posting the error.

    Actually it will be as follows.

    Please tell me the cause of the error.

    Hi,

     

    Try to recover your device:

    # Net core first
nrfjprog --recover -f nrf53 --coprocessor CP_NETWORK --log
# App core second
nrfjprog --recover -f nrf53 --coprocessor CP_APPLICATION --log

     

    If that still fails, please share the updated .log file(s)

     

    Kind regards,

    Håkon

    Thank you, Mr. Haakon.

    Executing two commands will result in an error.

    The error display is

    I found out a little bit about the cause.

    The customer's board has the DCCD terminal, DECD terminal, DCC terminal, and DECR terminal open.
    Even though I was in LDO mode, the following settings were not made in the prj.conf file.

    CONFIG_BOARD_ENABLE_DCDC_APP=n
    CONFIG_BOARD_ENABLE_DCDC_NET=n

    Therefore, it seems to be Resetloop.

    Please tell me how to cancel Resetloop.

    Hi,

     

    You can try to run this batch file, while powering on/off your custom board.

    :loop
nrfjprog --recover -f nrf53
goto loop

    Save this to "nrfjprog_recover_loop.bat" and run this. 

    This will continuously run the recover process while you power cycle your custom board. It can usually take a minute or two, but you are usually able to recover your board this way.

     

    Could you try this and report back?

     

    Kind regards,
