Deer Håkon

Thank you for answering.

You can now write in the following way before receiving an answer.

1.Add the following to prj.conf
CONFIG_BOARD_ENABLE_DCDC_APP=n
CONFIG_BOARD_ENABLE_DCDC_NET=n
2. Run the build
3.Run SEGGER's J-Link Commander
⇒Check the voltage value of the board
4. After running Connect at the above prompt, select nRF5340 on the selection screen
5. Execute writing

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,

Håkon

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.

Thank you, Mr. Haakon.

Executing two commands will result in an error.

The error display is

(base) PS C:\Users\TSP_M1\nrf5340_audio_demo6\tools> nrfjprog --recover -f nrf53 --coprocessor CP_NETWORK --log
[error] [Client] - Encountered error -102: Command enable_coprocessor executed for 78 milliseconds with result -102

I will share the .log at that time.

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

Håkon Thank you.

I made a mistake in posting the error.

Actually it will be as follows.

-- west flash: using runner nrfjprog
-- runners.nrfjprog: Flashing file: c:\Users\TSP_M1\nrf5340_audio_demo6\build\zephyr\zephyr.hex

NOTE: For additional output, try running again with logging enabled (--log).
NOTE: Any generated log error messages will be displayed.

Please tell me the cause of the error.

Hi,

[quote user=""]ERROR: Low voltage detected at the target. Please make sure the device is
ERROR: properly supplied.[/quote]

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

Kind regards,
