Hi Lance,

Could you try to instal Segger Embedded Studio v4.5.0 and test on that version ? It's the version recommended for SDK v17.0.2

Hi Hung Bui

Here is my compiler information

I found the same problem with BLE DFU sample code

(\nRF5_SDK_17.0.2_d674dde\examples\dfu\secure_bootloader\pca10040_s132_ble)

and I have confirmed the error 9 is returned by nrf_dfu_mbr_init_sd()

have any suggestions ?

Hi Lance,

If you remove UART transport do you see any problem ?
I have handled a very similar case a year ago which has very similar issue like yours:
SDK 17.1.0: secure bootloader runtime failure when compiled with current gcc (11.2.0)

Which compiler did you use ?
Please try to verify and make sure error 9 is returned by nrf_dfu_mbr_init_sd(). You can add a breakpoint, after nrf_dfu_mbr_init_sd() call.
