Please create a separate (private) ticket for the HW review.

Hi Simonr

It's solve, it's our hardware schematics problem, thanks for your reply.

Okay, but please note that the nRF5340 DK runs on 3.0V, so try set the external board to run at 3.0V as well. But this might not be the issue and I suspect HW issues on the custom board is the root issue here. Can you create a private ticket where you upload the schematics and gerber files of your custom board so we can do a HW review to make sure everything is okay on that end.

Best regards,

Simon

Hi Tina

How is the external board powered here? It should be powered by its own power source instead of by the DK to ensure correct programming. Do you have a picture of how you've connected the devices exactly? It could also be that the HW of your custom board isn't set up correctly. You can make a private ticket to get a schematics review of your HW done if you'd like.

Best regards,

Simon
