NRF52833 DK not powering up

[chethans]

Hi,

We have 4 NRF52833 DK being used for our development work.

Among that, 3 of them have stopped working and are not powering up.

They power up some times when connected to a power source for a long time, after 30 minutes or so. But this is rare.

Its very frustrating behaviour. We even got a new DK just couple of weeks back and it is also showing the same behaviour.

What could be the reason for this?

Thank you,

Chethan

Please update us with a capture of this noise when you can. I asked around and a colleague seems to be familiar with this issue. It usually occurs due to powering off and on the DK quickly. If you leave it off for a few (~10) seconds before turning it back on. Just try this a few times and you should see the DK working as intended. Please don't power the DK boards on and off rapidly as this should be what causes this issue.

Best regards,

Simon
