@Shay Ohayon: You can have a look here. Note that this is not applied for secure bootloader from SDK v11.

Is there a way to configure this in the hex file? when I typically download a merged bootloader+sd+app from mbed online compiler, they produce a single hex file, that when copied, automatically boots to the app and not the bootloader.

To make the bootloader aware of the usual method of firmware flashing (Jlink), we need to manually write “0x1” at the address (0x03fc00), disable CRC checking of the image and do a system reset.

$ nrfjprog.exe --memwr 0x03fc00 --val 0x1
$ nrfjprog.exe --memwr 0x03fc04 --val 0x0
$ nrfjprog.exe --reset

nrfjprog.exe is distributed with the nRFGo Studio and in my system it is located in the following directory.

$ which nrfjprog.exe
/c/Program Files (x86)/Nordic Semiconductor/nrf5x/bin/nrfjprog.exe
