OK, Thanks. we will use unsimultaneous DFU for the app core & net core.

Hi,

No, none of the samples that showcases simultaneous DFU from the unofficial bootloader gitrepository uses internal flash and simultaneous DFU. But if you follow the documentation I sent you regarding simultaneous DFU you should be able to add support for this without adding external flash.

The reason for why our samples only uses external flash is due to the application size. For simultaneous DFU you need to be able to fit both your app-core firmware and net-core firmware within mcuboot_secondary application slot, meaning that it will leave you with ~350kB available flash for your appcore firmware on your mcuboot primary application slot. It is not recommended to use simultaneous DFU and internal flash due to this limitation, but it is possible to do.

Kind regards,
Andreas

Hi AHaug,

According to the official documentation the Simultaneous multi-image DFU are based on Thingy:53 and the config also use extern flash to store mcuboot_secondary & mcuboot_secondary_1. And change to internal flash will lead to build error.

Is there some examples to used the Simultaneous multi-image DFU are based on internal flash?

Thanks

Chen

Hi,

The links in the repository should refer to the official documentation https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/device_guides/working_with_nrf/nrf53/nrf5340.html#simultaneous-multi-image-dfu and https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/device_guides/working_with_nrf/nrf53/nrf5340.html#simultaneous-multi-image-dfu

Kind regards,

Hi AHaug,

Our application is smaller than half of the internal flash, so i modify the example based on

this guide https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/nrf5340/mcuboot_smp_ble_simultaneous for a sample

if i comment the app.overlay & mcuboot.overlay like that to make extern flash disable, the build will failed

// / {
// 	chosen {
// 		nordic,pm-ext-flash = &mx25r64;
// 	};
// };

Is there any more documentation for a simultaneously DFU sample based on the internal flash of nrf5340?

Regards

Chen

Hi,

[quote user="kyozc"]I had check this link and it is use a extern flash for DFU part and the build will failed if not used extern flash. Is there a sample to do simultaneous DFU of both core with only inter flash.[/quote]

It depends on the application size. If your application is larger than half of the internal flash, then no. The theory here https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples explains this and links to the official documentation

If you can't do it simultaneously, then follow this documentation for a sample and remove the external flash partitioning https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/nrf5340/mcuboot_smp_ble_nonsimultaneous

Hi AHaug,

Thanks that i upload the "dfu_application.zip" for DFU. if i upload app_update.bin and net_core_app_update.bin separately it will be ok.

See this guide https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/nrf5340/mcuboot_smp_ble_simultaneous for a sample

I had check this link and it is use a extern flash for DFU part and the build will failed if not used extern flash. Is there a sample to do simultaneous DFU of both core with only inter flash.

Hi,

From the image you upload it looks like you're uploading the wrong image, but in your log it states that you're using "dfu_application.zip". If you want to do simultaneous DFU of both core you need to update with dfu_application.zip.

Could you state which files you've uploaded for DFU?

See this guide https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/nrf5340/mcuboot_smp_ble_simultaneous for a sample and https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/config_and_build/output_build_files.html to see what the different output files mean

Kind regards,
Andreas
