Initial Programming for nRF52832 on custom board

[Alexandria McKie]

Hi,

I am looking to perform programming on a nRF52832 on a custom PCB. So far I am planning to use an SWD connection with my nRF52DK to upload my application.

1. I was wondering if the nRF52832 comes with the softdevice132 and bootloader already programmed? 

If not, where can I find the correct bootloader projects?

2. Also, please advise if this would be the best script to do the upload:

nrfjprog --eraseall
// Flash the softdevice first
nrfjprog -f NRF52 --program file.hex --verify
// Next, flash the bootloader the same as above
// Next, flash the application the same as above

I would recommend to use the SWD as it is the only way to communicate with the device first time you program. 

The nRF52DK has two options for debug out, P20 and P19 https://infocenter.nordicsemi.com/topic/ug_nrf52832_dk/UG/nrf52_DK/hw_debug_out.html?cp=4_2_4_5_9

Not it does not. You can have the chip be preprogrammed during production before assembly, but I don't think that is what you are looking for. 

If not, where can I find the correct bootloader projects?

What do you plan to use in terms of SDK? 

We have the nRF Connect SDK (NCS) and the nRF5 SDK, 

Introduction to nRF5SDK and Softdevice

nRF5 SDK DFU Bootloader examples

And in NCS we have the MCUBoot

NCS Bootloader Link

Looks Ok. There is one extra command that I do preferer to use, and it is nrfjprog --recover as the first command.
