Not able to perform dfu over ble using nrf7002

[Rakshita]

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

I use overlay_bt.conf is to enable BLE DFU in peripheral_uart for nRF7002DK. 

nrf5340dk_app_sr_net.conf and nrf5340dk_mcuboot_sr_net.conf are for the MCUboot with the serial recovery of the networking core image feature. You can ignore them in the set-up stage.

You can check the similar cases
qspi_nor error using SPI: JEDEC id [00 00 00] expect [c2 28 17] 

 JEDEC id [00 00 00] expect [c2 28 17] in Matter template sample 

 spi_nor device id 00 00 00 does not match config c2 28 17

Also I don't have external flash, so for DFU internal flash would be used, no SPI needed

I was going through https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/ncs-dfu#mcetoc_1h90kb1ii2 this thread but nothing is happening and even the code is also not getting builded now

[Amanda Hsieh]

You can disable the external flash part in my sample.  

[Rakshita]

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

[Amanda Hsieh]

Remove the nrf7002dk_nrf5340_cpuapp.overlay and nrf7002dk_nrf5340_cpuapp.conf under the board folder in my sample. They are for SPI external flash.
