Hi.

I found the error message "Programming failed with exit code 33" when I try to start debugging on VS code. 
I could ever debug the borad several times until yesterday, but this suddenly happend.

I have two nRF52840DK board (that were bought in a same day ), the problem is happened in a one, and the other board is working correctly. 
The condition of the two evironments are same(ex. USB cable, connected PC).

I tried the command "nrfjprog --recover", then the following message was shown.

------------------

C:\Program Files\Nordic Semiconductor\nrf-command-line-tools\bin> nrfjprog --recover
[error] [ Client] - Encountered error -102: Command connect_to_emu_with_snr executed for 265 milliseconds with result -102

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

Could you tell me the cause or how to check devices?
Thank you.

Hi,

 

WARNING: Logging is unavailable. nrfjprog.exe does not have write
WARNING: permission for the log file

From the output here, it does not seem that your command prompt has proper write permissions here. Could you go to a folder where you have write permissions and enter "nrfjprog --recover -f nrf52 --log" and attach the generated .log file?

 

Kind regards,

Håkon

Hi,

Thank you for your reply.
I'll attach the log file, and the command message is bellow.
------
C:\Windows\system32>nrfjprog --recover --log
[error] [ Client] - Encountered error -102: Command connect_to_emu_with_snr executed for 233 milliseconds with result -102
ERROR: Unable to connect to a debugger.
[error] [ Worker] - An unknown error.
ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.
------

Is that J-Link Problem?
Do you have any idea to deal with this?
Please note that the other board is working correctly, so I think there is no problem with the J-Link driver.

Thank you.

Hi. 

I noticed the device is not identified on VS code, as shown in the bellow.

This similar to the following link.
https://devzone.nordicsemi.com/f/nordic-q-a/99180/nrf-connect-vs-code-extension-display-connected-device-as-unknown/422862

Threfore, I tried two measures in the thread.
1. nrfjprog --reset
2. downgrade nRF Connect

but, the problem is not improved.

Thank you.

[Håkon Alseth]

Hi,

 

Thank you for sharing the log.

Unfortunately, the log shows that the debugger isn't able to contact the nRF chip.

Is the firmware originally flashed onto the chip running? Ie. can you see LEDs blinking / UART log being populated?

 

Have you done any current measurement testing on this specific board, and ensured that there is a jumper present on "nRF current measurement" header?

 

One thing I saw from your logs is that you have a newer JLink version v7.92, while we bundle v7.88j with nrf-command-line tools. This shouldn't have an impact, but could you check with the version already present in nrf-command-line-tools v10.23.4?

 

Kind regards,

Håkon

Hi.

Central Periodic Advertising Synchronization Transfer (PAST) sample is written. The device outputs serial messages, so it seems to be still alive.

I updated nrf-command-line-tools, but this issue is not improved as you expected.
Thank you for your advice.

Is it possible that the written firmware cause this problem?
Is there how to update firmware without debugger?

Thank you.
