thank you ,Bjørn Spockeli ,,

my ladygaga,, It's all my fault ,,I found the problem,,I update application only before,,so ,I shielded the code carelessly #if 1 if (bootloader_dfu_sd_in_progress()) { nrf_gpio_pin_clear(UPDATE_IN_PROGRESS_LED);

    err_code = bootloader_dfu_sd_update_continue();
    APP_ERROR_CHECK(err_code);

    ble_stack_init(!app_reset);
    scheduler_init();

    err_code = bootloader_dfu_sd_update_finalize();
    APP_ERROR_CHECK(err_code);

    nrf_gpio_pin_set(UPDATE_IN_PROGRESS_LED);
}

#endif

In a word, Thank you very much!!!!

Thank you very much,Bjørn!but i am still have some questions 1.I am use Master Control panel v3.9,use this versions to make softdevice+bootloader,it can be update bootloader?

Dear Bjorn,

Thank you very much for your soon feedback!

I had try to used SoftDevice + Bootloader(single bank) to update,but not helpful.

nrf.exe dfu genpkg --softdevice s110_sd.hex --bootloader s110_sbl.hex --application-version 0xFFFFFFFF --dev-type 0xFFFF --dev-revision 0xFFFF --sd-req 0xFFFE s110_sd_sbl.zip

I had used this command, so, could you tell me this command is right?Thanks!wait your message.

You can convert the dual_bank_bootloader project to single bank by switching dfu_dual_bank.c with dfu_single_bank.c, please see attached pdf.

DualToSingleBank.pdf

Please note that when updating the bootloader from dual to single bank you must update the SoftDevice + Bootloader, otherwise it will not work.

EDIT: The attached image contains the S110 SD+ S110 Single Bank Bootloader and was created with nrfutil from Master Control Panel v3.10 using this command

nrfutil dfu genpkg s110_sd_sb_bl.zip --softdevice s110_softdevice.hex --bootloader s110_single_bank_bl.hex --application-version 0xFFFFFFFF --dev-revision 0xFFFF --dev-type 0xFFFF --sd-req 0xFFFE

s110_sd_sb_bl.zip

After the update you can check if the update was sucessful by reading back the data stored at 0x0003F75C using the following command in nrfjprog

nrfjprog --memrd 0x0003F75C --n 16 --w32

which should display the following in your command window

0x0003F75C: 676E6953 4220656C 006B6E61 00000002   |Single Bank.....|
