nRF52833 custom board cannot recover

[MatejSt]

Hello!

I have tried to program a module containing the NRF52833 with a Bluetooth Long Range example. The programming failed and the module cannot be programed any longer. I have tried recovering it with nrfjprog with no success.

Z:\>nrfjprog --recover --family nRF52 --log
Recovering device. This operation might take 30s.
ERROR: Recover failed. Please make sure that the correct device family is given
ERROR: and try again.

I notice the VTref voltage is kind of low... could this be the problem?

Any help would be greatly appreciated.

[Jared]

Hi,

What voltage do you measure on VDD and the RESET pin?

regards

Jared

[MatejSt]

Roughly 3.1V on both of them.

[Jared]

Could you share the schematic and layout files? I can make the case private first if you prefer it. 

[MatejSt]

It's a Chinese development board, and the reset pin was pulled up internally, so the problem is now resolved.

Thank you for your help.
