Unable to flash nrf52820 using nrf52833DK debug out.

[noob_123]

Hi,

I have a nrf52820 on a pcb without 32Mhz crystal. I am using nrf52833DK to flash the nrf52820 on the pcb using debug out port on DK. I am able to see the connected device as nrf52820 on vscode but it shows error while flashing.

--log

nrf connect programmer

What is causing this problem and where to start looking for a problem? Is this due to the absence of 32 Mhz crystal?

If the debug port is not open anywhere else like other RTT terminals then try "nrfjprog --recover" in the command line and try to flash again.
