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.

Hi

Can you show me what build command you've used for building the sample? You can also try sing west flash --recover to make sure you erase what is already on the nRF54H20 when flashing it so there are no strange overlaps.

Please also share what version you have of nrfutil and nrfutil device with the commands:

• nrfutil --version
• nrfutil device --version

Best regards,

Simon

I have used "west build -p -b nrf54h20dk/nrf54h20/cpuapp" command.

But after that LEDs don't blink.

Just to make sure, your sample is the same as in ..\ncs\v2.7.99-cs2\zephyr\samples\basic\blinky correct? I just tested on my end with an nRF54H20 DK and was able to build and flash with the commands you describe here and the LED on the DK blinks without an issue.

I see that you have an older nrfutil version than me (with v7.13.0 on my end), so you can try upgrading that. The other difference is that you build the project out of tree. As I build the sample within the ncs\v2.7.99-cs2\zephyr\samples\basic\blinky folder, so you could try that as well on your end. 

If you still have no luck. Try uploading the full build log here so we can check what's happening.

Best regards,

Simon

I have upgraded the nrfutil to v7.13.0

I have also built the blinky within the zephyr\samples\basic\blinky folder. 

But this didn't help me. Here is my build and flash log.

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
