NRF5340 MCUBOOT DFU failed: Slot image has no hash TLV

[kyozc]

Hi Nordic,

We have a custom board based on nrf5340(no extern flash). And the DFU works ok with only app update based on ncs 2.5.0

CONFIG_BOOTLOADER_MCUBOOT=y

CONFIG_IMG_ERASE_PROGRESSIVELY=y

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU_SPEEDUP=y

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU_VALIDATION=y

But we cann't perform APP+NET core update by add.

CONFIG_NRF53_UPGRADE_NETWORK_CORE=y

# CONFIG_UPDATEABLE_IMAGE_NUMBER=2

The nrf connect app always show error below:

What should we do if we want to do both application & network app update

Thanks

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

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.

Regards

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,

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

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,
Andreas
