nRF52840 bootloading

[Shaked Aharon]

Hello,

I designed a PCB using nRF52840 for controlling the board.

I have physical access to the following pins : SWDIO, SWDCLK , VSS , VDD , nRESET.

What is the boot loading sequence for the first time boot ?

Please guide me on the steps for the first time bootloading.

I assume you have a programmer, like the following J-Link BASE Debug Probe .
Connect up common ground and the pins for programming to the debug probe. Power on the board and see if the Debug Probe detects it using the Segger J-Link Flash utility.
