nrf_dfu_transports_init() error in background dfu

[alex kim]

Hi,

I am using 

• PCA10056
• SDK 15.3.0
• Keil IDE
• The soft device is S140 
• JLinkRTTViewer for debug

I am testing background serial-dfu.(refer to https://devzone.nordicsemi.com/f/nordic-q-a/46336/bootloader-no-transport-dual-bank-dfu-and-dependencies)

I erase 52840 whole and write SoftDevice & bootloader.

I used keil debug to download the app and run.

An error occurred with the attachment.

Please advise

Alex

Hi Vidar,

Thank you for your kind reply every time.
I'm using secure_bootloader \ pca10056_uart_debug.
a nrf_fstorage_nvme.c is used for secure_bootloader.
a nrf_fstorage_sd.c is used for background dfu by using ble.
I'm not sure if "SOFTDEVICE: INVALID MEMORY ACCESS" is occurring.

Hi Alex,

The screenshot in your previous response shows that p_fs->p_api was set to "nrf_fstorage_nvmc" when you got the assertion. Please double-check this.

Hi Alex,

Are you still getting the Softdevice assertion when you perform background DFU? I meant to ask if you could double-check if the Softdevice backend is indeed used because the screenshot you posted earlier shows it's not.

Hi Vidar,

yes, i still getting the Softdevice assertion.
