nRF52833 custom board cannot reprogram.

[binhla]

Dears,

Our custom board using nRF52833 cannot connect to Jlink after flashed a program.

I had the board connected with the Jlink via VCC, GND, SWDCLK, SWDIO and RESET pins.

I tried to run: nrfjprog --recover as the guide here

But it not working.

Is there a way that I can re-program the nRF52833? 

Why did this problem happen? 

Best regards.

Hi,

Maybe this was because you copied the dk files for the custom file. I would suggest you to take a look at the Tutorial for building for a custom board for the nRF Connect SDK.

Dears,

Thank you for your prompt respone.

What is the dk fils you said?

I made the custom folder as guilde in the Board porting guide.

This error already costed me a lot of nrf52833 SOCs.

So now I am very afraid to make any more test if there is no way to recover my nrf52833 or at least a good explant of what is wrong with my custom board files.

Best regards!

Hi,

Does your custom board have an inductor for the DCDC converter? If you do not have, but you have configured DCDC enabled, then this might be a problem.
