CRC Error using DFU of nRF Toolbox

mino

I want to update over BLE with using DFU tool. But do not start updating process.
DFU tool indicates "Enabling DFU Bootloader".
Bootloader stops at memcpy() of dfu_ble_peer_data_set().
Where/What should I confirm ?

Application Hex File is merged app_valid_setting_apply.hex.
DFU Update Type is Dual Bank type.
Application size is about 20kB.

S110 v8.0.0
SDK v8.1.0

    Is the DFU Tool our nRF Toolbox app? Are you using the bootloader example from the SDK or have you modified it? dfu_ble_peer_data_set() is called by the application with DFU support and not the Bootloader. Why have you merged the application with app_valid_setting_apply.hex? This file should only be merged with the bootloader and not the application.
