Happy to know you find the patch and fix the issue. 🙂

Hello Amanda Hsieh finally we managed to get the simultaneous DFU on both cores.

Using this patch the net_core_app_update.bin and dfu_multi_image.bin files are generated correctly and the simultaneous update works fine following the procedure I wrote in this post.

It would be really useful if the patch is applied in a future release.

[quote user="lbudde"]We made changes in the child image[/quote]

What changes did you make? Is it possible to add "printk("build time: " __DATE__ " " __TIME__ "\n");" in your custom network core application and make a difference?

Hi Amanda Hsieh , we are not working with the HCI_IPC sample, but with a custom network core image (which includes B0N) -> we tried to enable all the configs that were enabled in your project, in the build/hci_ipc/zephyr/.config file related to firmware updates.

We made changes in the child image, and apparently dfu_target_mcuboot is aware of that after receiving the images, as image-0 and image-1 show upgrade scheduled

But after application core finishes updating, the network core update is never executed from the application core, and we don't see any warning or error log even after increasing verbosity.

We would like to know is this would be a typical symptom of a missing configuration enabled, for example application core not being able to comunicate with network core (we would expect some error logs if this was the case). As we don't use BLE, we don't have MBOX and PRMSG enabled, could this be related?

If you consider it useful I can send you our source/build files.

Thanks

Hi,

Did you make any changes to the HCI_IPC sample for the network core to update? If the code is the same, it will not be updated. You can try to add

printk("build time: " __DATE__ " " __TIME__ "\n");

to build with differences.

Hi Amanda, I work with tomas_mjp , we have been checking your sample and modified some of the configurations in our main project and child images (and verified them in the built zephyr/.conf files), but still can't get the updater to trigger the network core update.

The main structure of our project is described here, to summarize:

only 1 project, with main application core firmware
network core firmware being built as a child image of the application core
mcuboot enabled in application core through prj.conf
mcuboot included in network core as described here, with an extra b0n.conf being applied in our network core project folder, inside child_image folder

Adding a little more verbosity, the logs from application core during updating process are the following:

and in the network core we can see the B0N bootloader banner, and the application banner:

I understand that your sample works with the HCI_IPC sample for network core, do you think it is possible that some configuration from that sample can be missing on our side to enable the network core update? Is there any advice on particular configurations to look for? considering we are already following what is described here and here, and there are no big differences with your sample project (except for working without BLE, and not basing the update on FIRMWARE_VERSION but just forcing it to always execute).

Thanks,

Leopoldo.

build/zephyr/dfu_application.zip only contains app_update.bin and manifest.json in my case, there is no file for netcore

If I understand correctly I'm writting the appcore and netcore images correctly, I just need to MCUboot to perform the netcore image swap

Appcore logs during boot:

*** Booting nRF Connect SDK v3.5.99-ncs1 ***
I: Starting bootloader
I: Image index: 0, Swap type: test
I: Image index: 1, Swap type: test
I: Image 0 upgrade secondary slot -> primary slot
I: Erasing the primary slot
I: Image 0 copying the secondary slot to the primary slot: 0x35ef0 bytes
I: Bootloader chainload address offset: 0x10000

Hi,

Please upload build/zephyr/dfu_application.zip to update.
