timeout occured while handling debug power

[uodami]

Hello,

I am trying to flash and debug a custom board using the Raytac MDBT42Q-512KV2 that uses the nRF52832 module mounted. I tried this using the jlink plus and the nRF52 DK.

When I try to refresh the connected devices in VS Code, I get this error:

Device error: A timeout occured while handling debug power: Timed out trying to power sys and debug region (Generic).

I checked the SWD lines, measured power, etc. All looks good.

I saw on a similar thread that this might be caused by accidentally changing the RESET pin. The suggestion was to pull the RESET pin high (by connecting to VDD for instance), which I did. But the problem persists.

I also tried to recover the board, but I get the same error when I do so.

Any suggestions on what this error actually means? What am I missing here?

Thank you.

Cheers,

uodami

Hi

What voltage is the Raytac board powered with here? Note that the board should be powered separately when using an nRF52 DK as the debugger device.

Do you have the full log from when you try to connect the debugger to the Raytac board? Has the board been flashed with anything at all, or this is a completely "fresh" custom board that should be empty?

Best regards,

Simon
