If it's bootloader from SDK v6.0 I think bootloader update is not supported . Please have a look here.

Thank you for the help. The issue is solved. I changed the optimization level to 'Level 3' and I changed the BOOTLOADER_REGION_START to 0x0003c00. As well as I changed IROM settings also. Now it works fine. But when I try to upload bootloader from single bank dfu it gives error as I mentioned before. Does it supports bootloader and softdevice upgradation?

@Mukesh: The size of the bootloader is bigger because I removed optimization , as far as I remember. You can enable optimization and see if it can get to the similar size with the dual bank bootloader. Also please modify the bootloader start address so that it has the same start address as your dual bank bootloader.

If you want to modify the dual bank bootloader yourself, try look for the comment "SINGLEBANK PATCH" in the code.

Hi Mukesh, how big is your application ?

Which chip are you testing with, what is the flash size of it ?
