I am using a module MS12SF1(nrf5340 + nrf7002). I wanted to perform dfu over ble by using nrf7002dk_nrf5340_cpuapp_ns or nrf7002dk_nrf5340_cpuapp build configurations but as soon as I enable the dfu configurations and flash the code I don't get anything in the logs and bluetooth also stops advertising
I was trying this on peripheral_uart sample code
I followed the course as well but nothing helped
What can be the issue?
Using sdk v2.6.1
Hi,
It's not clear to me what is the issue from the limited information.
Here is my test project peripheral_uart_nrf7002DK_DFU.7z which can run peripheral_uart with BLE DFU on nRF7002DK in NCS v2.6.1.
The build command is
west build -p -b nrf7002dk_nrf5340_cpuapp -d build_nrf7002dk_nrf5340_cpuapp -- -DOVERLAY_CONFIG=overlay-bt.conf
It requires extra board/BLE DFU configs and overlay files for nRF7002DK.
“Beware that this code/configuration is not fully tested or qualified and should be considered provided “as-is”. Please test it with your application and let me know if you find any issues.”

Hi Amanda
Sorry got busy with other priority tasks
So now I am back to working with DFU
I wanted to share the custom board build configuration files as I am not able to build the code with it but able to build it with the default present nrf7002dk_nrf5340 build configuration
It would be great if u can review it once and let me know what I can add
The module which we are using is MS12SF1 (nrf5340+nrf7002)
arm.zip
Also wanted to confirm that do I need to add nrf5340dk_app_sr_net.conf, nrf5340dk_mcuboot_sr_net.conf and overlay_bt.conf files additionally?
One more thing I added the necessary configurations which u added in your code in my code, earlier zi was using spi4 for sd card so I changed it to spi3 and using spi4 for flash
I get
[00:00:00.002,288] <err> spi_nor: Device id 00 00 00 does not match config c2 28 17 this error on rtt
Want to add one more point
When I tried executing the code u sent above, ble was not advertising
Only the spi part or configurations too
Can u tell me exactly which configurations are related to external flash so that I can disable them, little bit confused
Remove the nrf7002dk_nrf5340_cpuapp.overlay and nrf7002dk_nrf5340_cpuapp.conf under the board folder in my sample. They are for SPI external flash.
And what about the nrf7002dk_nrf5340_cpuapp.overlay and nrf7002dk_nrf5340_cpuapp.conf files present in child_image/mcuboot folder as in overlay file external flash is selected
Also don't I need to call any function in main like the one done in https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/ncs-dfu#mcetoc_1h90kb1ii2 where smp_bt_register() was called?
Tried multiple ways to run the code by removing the configurations or adding them but nothing is working
Am I missing something?
Also how to decide whether to use static or dynamic configuration for partition?
Its very urgent

Not anymore in v2.6.1.

Are you able to build without issue? I see you created a new case Regarding flash overflow when dfu is enabled, and I have answered it.

Let the partition manager generate the partition automatically, and then use that partition as the static partition.

Yes I was able to perform dfu now
Actually I had to add the SYNTH clock configuration in the mcuboot.conf too so that the device can advertise after enabling boot
After enabling the clock it was working fine.
But the issue is that as soon as I integrated the dfu part in my original code I got flash overflow issues
