What are the flashing pins for the nRF52820 chip and how do I flash with the flashing pins?

[Gotak]

Hi,

I want to know what are the flashing pins for the part nRF52820, and what is the procedure for flashing the program with these pins? Should I use the comands? If yes, please help me with the commands?

Note: I am using nRF connect desktop SDK

Thanks,

Gotak

So when I am trying to build the configurations for my nRF52820 custom board with nrf52833dk_nrf52820 with the central sample, I am getting this errors:

The build log indicates that the application is too large to fit in Flash and RAM of nRF52820:

Try building a simpler application.

I am trying to flash the code image into my external custom nrf52820 board with my nrf52833 DK.

Is these any board switch settings to do on the nRF52833 DK to flash on the nRF52820 externally?

No, the nRF52833 DK will select the external board based on voltage level on VTG pin. If you are connecting the external board through P20 header, please connect VTG pin to VDD of the external board. Note that the on-board J-Link on the DK does not support voltage level conversion, so the external board must be supplied at the same voltage as the DK (3.0V).
