No bootloader was found error - DFU buttonless on nRF52833 custom board

Hi, I'm running a DFU ble_app_buttonless_dfu on nRF52833.
Unfornately, my board is not supported it use pca10100. SDK 16 only supports pca10056 and 10040.
I have used pca10056 (s140) and adjusted some configurations based on ble_app_uart_pca10100

// Memory Segement in Linker

FLASH RX 0x0 0x80000;RAM RWX 0x20000000 0x20000;uicr_bootloader_start_address RX 0x10001014 0x4

I have some confusions about adjust RAM for Bootloader and Flash.
1. After adjust above configurations My application was built completed but when I debug I got this problem. I think the reason come from RAM, ROM  address
