SDK15.3 buttonless dfu example cant get into dfu mode on pca10040 using armgcc build.

[Mark P. Mendelsohn]

nRF Connect log shows DFU mode cannot be achieved. Same test on SDK15.2 worked.

Comparing the ld files of 15.2 and 15.3 shows uicr_bootloader_start_address and uicr_mbr_params_page

are quite different. 

SDK15.2

uicr_bootloader_start_address (r) : ORIGIN = 0x100010014, LENGTH =0x4

uicr_mbr_params_page (r) : ORIGIN = 0x10001018, LENGTH = 0x4

SDK 15.3

uicr_bootloader_start_address (r) : ORIGIN = 0x00000FF8, LENGTH =0x4

uicr_mbr_params_page (r) : ORIGIN = 0x00000FFC, LENGTH = 0x4

Is this why SDK15.3 DFU is not working?

Hi,

In 15.3.0 we started using the MBR section to hold the bootloader start address instead of UICR.

Are you using make flash and make flash_softdevice commands for flashing the application/bootloader ?

If yes, see this post :

flash_sdbl: default
	@echo Flashing Softdevice and bootloader
	mergehex -m $(OUTPUT_DIRECTORY)/nrf52832_xxaa_s132.hex $(SDK_ROOT)/components/softdevice/s132/hex/s132_nrf52_6.1.1_softdevice.hex -o sdbl.hex
	nrfjprog --program sdbl.hex --chiperase -r

Similar post for Keil can be found here.

[Mark P. Mendelsohn]

We use a separate script to merge all 4 components before flashing the pca10040 so this does not seem to be the issue we are experiencing. 

Additional info on this issue. nRF Connect on Android can see the Buttonless device, DFU is requested, the device goes into DFU mode since DfuTarg can be seen but stops. Manually connecting to the Dfutarg advertising device and retrying the DFU will go to completion. So the issue seems to be nRFConnect cannot complete the DFU without manual intervention or SDK15.3 is not allowing it.

Hi,

I don't see anything wrong in the log. The DFU bootloader is found, and the DFU service is started.

11:04:27.532 [DFU] Scanning for the DFU Bootloader...
11:04:27.798 [DFU] DFU Bootloader found with address D3:CD:8A:FD:E1:52
11:04:27.834 [DFU] DFU service started

Did you connect manually here? If yes, could you upload a log where you don’t manually connect?
