MBR or blank directory ?

[kizhimon]

I am new to nRF SDK. I am starting development for my nrf52810 based board. I am using blinky example from nRF5 SDK. I am using nRF52 DK board to flash and debug my nRF52810 board. i am using segger Embedded studio IDE.

Which folder should I select to start with, MBR or BLANK ?

I already saw few answers in the forum, but I did not understand ? Could you please clear this ? I want to blink an LED to start with

You can use the "blank" version if you just want to blink some LEDs. The difference between these 2 configurations is that the 'mbr' one is configured to start above the Master boot record (link) in memory as the picture below shows. And the MBR is only needed when you want to support DFU on your device (I.e. Firmware update over BLE, UART, etc and not through the Debug interface)

That's clear now... Thanks
