Problem with mesh DFU

[Gerry]

Hi,

I already asked a similar question 6 month ago (ticket) but we never got a solution to this.

Now, after 15 month of development, our mesh-applications are almost finished and we really need DFU.

To be able to upload code, I open a private ticket here.

Our mesh-client is now running on Mesh SDK 3.1.0 and SDK 15.2. This client is supposed to get DFU-updates via UART0.

Our script for programming the client:

@echo off
for /f "tokens=1,2 delims==" %%a in (version.ini) do (
	if %%a==client_version set client_version=%%b
)
echo __________Connectivity Client Version: %client_version%__________
@echo:
echo __________Device page erstellen____________________
cd pc-nrfutil-mesh_dfu
cd dfu
REM bootloader_config_default.json erstellen (bestehende Version der Firmware)
set /a "prior_version=%client_version%-1"
 (
   echo {
   echo     "bootloader_config": {
   echo        "bootloader_id": 1,
   echo        "bootloader_version": 1,
   echo        "company_id": 89,
   echo        "application_id": 1,
   echo        "application_version": %prior_version%
   echo    }
   echo }
 ) > bootloader_config_default.json
python device_page_generator.py -d nrf52840_xxAA -sd "s140_6.0.0" -o ../client.hex
cd ..
@echo:
echo __________Programmieren____________________________
nrfjprog --recover -f NRF52
REM use --verify to verify programming with --program
nrfjprog --eraseall
nrfjprog --program ../../Mesh_SDK/bin/softdevice/s140_nrf52_6.0.0_softdevice.hex --chiperase --verify

nrfjprog --memrd 0x10001014
nrfjprog --readcode my_flash_dump.txt
nrfjprog --reset
@echo:
cd ..

pause

Our script for updating the client: 

@echo off
for /f "tokens=1,2 delims==" %%a in (version.ini) do (
if %%a==client_version set client_version=%%b
if %%a==Comport set Comport=%%b
)
@echo off
echo __________Connectivity Client Version: %client_version%__________

cd pc-nrfutil-mesh_dfu
@echo:
echo __________DFU file erstellen_______________________
nrfutil dfu genpkg --application ..\..\Source\connectivity_client\build\connectivity_client_release\connectivity_client.hex --company-id 0x00000059 --application-id 1 --application-version %client_version% --sd-req 0x00A9 --mesh client.zip
@echo:

nrfutil --verbose dfu serial -pkg client.zip -p COM%Comport% -b 115200 -i 300 -fc --mesh
@echo:

pause

The output when updating:

I already tried making changes like described here, but this didn't help.

What could be the problem here?

Best regards

Hi Gerry, 

Your client.zip worked fine for me here. 

I haven't tested to flash your client.hex file but only use our SDK's dfu example to do a DFU. (I'm not sure if you use the same UART pins in your client.hex,) 

Could you try testing using our DFU example ? I attached our main.c file with the fixplease replace with the original main.c and send us the RTT log file after you test. The .hex of the DFU application is also attached. 

dfu_nrf52840_xxAA_s140_6.1.0.hex
