You can use nrfjprog to flash the combined hexfile to your nRF51822, its a part of the nRF5 Commandline Tools, which can be downloaded using this link. Once you have installed it you can use the following terminal command to flash the combined hex file to the nRF51822:

nrfjprog -f nrf51 --program <name of combined hex file>.hex --chiperase --verify

It would be easier if you uploaded the hexfiles so that I could see where the conflict is.

What about the application, does it have anything placed at 0x3FC00?

The two memory windows does not show the same addresses, the right one does not show 0x3FC00.

It could sound like you application places something at the same address, i.e. BOOTLOADER_SETTINGS_ADDRESS. Could you attach the application hex and the bootloader hex with BANK_VALID_APP set to the question?

thx,now I know how to calculate the address.and I find when I change < uint8_t m_boot_settings[CODE_PAGE_SIZE] attribute((at(BOOTLOADER_SETTINGS_ADDRESS))) attribute((used)) = {BANK_VALID_APP};> then I can't combining this hex.NOT add = {BANK_VALID_APP} ,I can combining. but if not add = {BANK_VALID_APP};,when I use keil download application.hex ,dfu will not distinguish . and dfu must update once then can run application. what should i do?

If the bootloader has 0x3C800 as the start address, then you have to set the size of the application flash section so that it ends where the bootloader starts, i.e. Application IROM1 size = BOOTLOADER_START_ADDRESS - APPLICATION_START_ADDRESS = 0x3C800-0x14000 = 0x28800.
