Not able to perform dfu over ble using nrf7002

Are you testing on nRF7002DK?

Do you update the file with the same static partition? You can duplicate build/partitions.yml, place it in the app folder, and rename it to pm_static.yml to build.

Hey Amanda
The code which u shared above for dfu for DK I was testing using external flash as the secondary slot
The issue is that the dfu worked for the first time but when I tried to perform it for a different file it was continuously failing
I was getting no_file_slot(9) error as it was not clearing the older image

I found

CONFIG_MCUMGR_GRP_IMG_ALLOW_ERASE_PENDING=y this configuration, by doing this I wasn't getting no_file_slot error but was getting hash not found error

What can be the reason??

Refer to the Memory footprint optimization doc. to reduce the size.

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

Hi,

[quote user="Rakshita"]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[/quote]

Also, remove them.

[quote user="Rakshita"]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?[/quote]

Not anymore in v2.6.1.

[quote user="Rakshita"]Tried multiple ways to run the code by removing the configurations or adding them but nothing is working[/quote]

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.

[quote user="Rakshita"]how to decide whether to use static or dynamic configuration for partition?[/quote]

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

Am I missing something?
Also how to decide whether to use static or dynamic configuration for partition?
Its very urgent

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

RE: Not able to perform dfu over ble using nrf7002

Rakshita — Fri, 23 Aug 2024 15:58:23 GMT

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

RE: Not able to perform dfu over ble using nrf7002

Amanda Hsieh — Fri, 23 Aug 2024 14:20:32 GMT

You can disable the external flash part in my sample.

RE: Not able to perform dfu over ble using nrf7002

Rakshita — Fri, 23 Aug 2024 14:17:57 GMT

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

Hi,

[quote user="Rakshita"]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?[/quote]

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.

[quote user="Rakshita"]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[/quote]

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

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)
devzone.nordicsemi.com/.../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

Hi,

It's not clear to me what is the issue from the limited information.

Here is my test project devzone.nordicsemi.com/.../peripheral_5F00_uart_5F00_nrf7002DK_5F00_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.”
