Blinky example doesn't work on NRF54H20-DK

[Mykhaylo]

Hello!

I have NRF54H20-DK and I'm trying to run the Blinky example.

I am able to build and program the DK, but nothing happens on LEDs.

Could you please help what else I should check?

NRF54H20-DK: 0.8.2

nRF Connect SDK: v2.7.99-cs2

Thanks.

Please try reading out the boot status with nrfutil device x-boot-status-get --traits devkit and let me know what this returns (0x000000 means the boot status is okay).

You can try reading info from the DK with  nrfutil device x-adac-discovery --traits devkit and report back what you're seeing there.

Finally, you can try erasing the states of the local domains on the nRF54H20 before running a recover, with 

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
nrfutil device recover

Best regards,

Simon

This sequence did not help me. I still can't see anything on the LEDs after flash.
