Hi
I am trying to merge BLE DFU and UART DFU bootloader(SDK version is "nRF5_SDK_17.0.2_d674dde"),
after merged, when I process to DFU mode , It show below error
<info> app: Inside main
<debug> app: In nrf_bootloader_init
<debug> nrf_dfu_settings: Calling nrf_dfu_settings_init()...
<debug> nrf_dfu_flash: Initializing nrf_fstorage_nvmc backend.
<debug> nrf_dfu_settings: Using settings page.

<error> app: Could not initalize DFU transport: 0x00000009
<error> app: Received an error: 0x00000003!
Then I checked the program and found that the problem was nrf_dfu_ble.c => ble_stack_init() => nrf_dfu_mbr_init_sd()
the program always stuck in nrf_dfu_mbr_init_sd()
Am I missing something when merging the files?
