nrf54h20-dk flash failed.

[Bruce2048]

I strictly followed the tutorial in the document to develop

(docs.nordicsemi.com/.../ug_nrf54h20_gs.html

but the west flash still failed in the end. Here I record my operation process.

1.ncs version(with west update success)

2.the sample zephyr/samples/sysbuild/hello_world also build success.

3.some nrfutil command

4.flash always failed.

So please help to solve the flash issue.

Hi Bruce, 
Flashing the application before the BICR could be the culprit here. I think we need to improve the documentation. 
Could you try to do the following: 
1. Make sure you have latest nrfutil and nrfutil device 

2. Run the following: 
nrfutil device x-boot-mode-set --boot-mode safe --traits jlink
nrfutil device erase --all --log-level trace --core Application --traits jlink
nrfutil device erase --all --log-level trace --core Network --traits jlink
nrfutil device x-boot-mode-set --boot-mode normal --traits jlink

3. Try to flash BICR again and continue the bring up

4. If it doesn't work please try measuring the voltage on these pins: 

[Bruce2048]

OK.Thank you for your reply.

It still failed.And I think it's no need to continue to the other steps.

Here is the voltage:

1:5.05V

2:0.00V

3.1.787V

4.0.803V

5.0.843V

Hi Bruce, 

The voltage on the pins seems to be OK. 

I'm afraid we're running out of idea how we can recover the board. 

Do you have other board that can be used ? If you do, please make sure the onboarding process has to be done before flashing anything else. 

I will try to check internally if we can find a solution and let  you know if there is any update. I afraid that in the mean time you would need to find a new board to continue the development. 

[Bruce2048]

Yes, I have another one, and the other one has been set up successfully.

Looking forward to your early reply, because one board is not very convenient to use, both my colleagues and I need to use.

Thank you.
