With this application setting, when i upload application.zip file through bootloader, then application file is not uploaded and process is not getting completed.

No bootloader found issue is coming.

No bootloader found issue is coming.

So the ble_dfu_buttonless_async_svci_init() call in the application is still generating ERROR 4 [NRF_ERROR_NO_MEM]?

Can you post the .map files for the compiled application and the bootloader?

Best regards
