@Yogesh: Sorry for late response, first please verify you can use the bootloader and start your application at the normal address of 0x1F000. Then try to change the start address to 0x20000 and then modify MAIN_APPLICATION_START_ADDR to match with that. After that you flash the bootloader, and then you update the application via DFU.

Ok, then you should only need to call nrf_bootloader_app_start(MAIN_APPLICATION_START_ADDR) in main after you have done what you need to do in the bootloader, where MAIN_APPLICATION_START_ADDR is set to the start address of your main application.

Thanks for the reply... Yes..you said exactly right. I want only bootloader(where small application runs) and then jumps to main application..

When you write I only want to boot the application and jump to blinky project address.For that i am using secure dfu example code. Do you mean that you do not want the DFU functionality, but only a bootloader(i.e. small application that executes first) and jumps to the main application?
