Uploading serial bootloader into nrf52832 sparkfun breakout board

[SaiTeja]

Hello , I recently bought sparkfun's nrf52832 breakout board. It comes with preprogrammed serial boot loader. How ever after flashing code from nrf52 DK into my nrf52832 sparkfun breakout board, serial bootloader has been erased. I would like to take my spark fun board to previous state. Please tell me how to program serial bootloader into it.
Here is the link for sparkfun github repository. github.com/.../nRF52832_Breakout This repo contains firmware folder. Is that useful to solve my purpose.Please help me in this regard.

Looks like you can program the serial bootloader using the C + D pins connected to an SWD programmer like a Segger J-Link. Look at the "Resources and Going Further" Section here: https://learn.sparkfun.com/tutorials/nrf52832-breakout-board-hookup-guide/all
The bootloader code is in that repo you linked.

I'm doing my part to fix at least one dead end thread on the internet, not for the OP but for people in the future. If they don't want an answer then someone else should clean up the forum.

Thank you for your valuable contribution MelvynIanDrag!

Yes, of course.

Just so long as you did realise.

Unlike pipixia, apparently
