A good method to flash softdevice + bootloader + application with a programmer is described on this thread. You can merge the files together in order to only flash once, or you can flash the files separately, see the latest updates on the thread.

Found the problem. The boot switch, DFU bootloader (that shipped along with blefriend) and bootloader settings was not programmed correctly (offset 0x3c000 - 0x3ffff)

The last page in the flash images I've uploaded are same, the first 88K (bootloader) is same as well. But the flash image with DFU updated application works while the other does not.

It does not make sense.

Edit: Both have the same application 11728 bytes at offset 0x16000

Usually it is the last page in the program memory.

Do you know the flash address where the bootloader stashes the CRC ? Is it in the bootloader settings section ?

Once you do your first upgrade via DFU, it stashes a CRC of the application in flash. When you reprogram via the J-Link or other programmer the CRC of what you programmed will not match what the DFU has stored in flash. The bootloader will calculate the CRC of the application in memory and compare it to the stored value. If they do not match it considers the application corrupt and will not jump into the application.

The quick and dirty fix I do when this occurs is to reprogram the DFU with the programmer which also erases the stored CRC in flash.
