Programming custom PCB nrf52840

[Ashish]

How can I use nrf 52840 PDK to program custom PCB made using nrf52840 soc and reference circuitry suggested in datasheet, Circuit configuration no. 6 ??

Is there any software configuration required before downloading codes?

Hi,

You can use the debug out port on your PDK: Debug output.

There is no software or configuration required to do this. It should work out of the box. Just make sure you have access to the GND, VDD, SWDIO, SWDCLK pins on your custom PCB.

Thanks MartinBL !!!

I've attached external LC filters  with both DC/DC converters. I will be activating DC/DC in place of LDO as they are more efficient. To enable them I would be modifying registers 

NRF_POWER->DCDCEN   &

NRF_POWER->DCDCEN0 

Further, In high power mode, I will be selecting VDD by

NRF_UICR->REGOUT0 

I hope these configurations will not cause any issue in proper functioning.

Sounds like a solid plan!

It is :) and works !!!
