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.

It seems from the build and flash log that everything executes successfully, so you're saying that the LEDs simply don't blink, correct. Have you done the preliminary steps for setting up your DK. If not, please check out the Getting started guide for the nRF54H20 DK here, as there are some bring-up steps required before the first time you use the DK.

Best regards,

Simon

Yes, I have already done that. How else can I check the board is working correctly?
