update bootloader from dual bank mode to single bank mode failed in sdk8.0

[rc766437]

HI all: Because the application code is relatively small, bootloader is used dual_bank_mode, but now the application code becomes large, OTA can not upgrade, I would like to upgrade to dual_bank_mode until sigle_bank_mode by OTA , but I found it is same dual_bank_mode after upgrading(I had try to used softdevice+bootloader but can't update bootloader,only upgrade bootloader also can't), can I how realized it , I use the SDK 8.1

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.

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!!!!
