[NCS 2.7.0] Sysbuild config for nRF5340 Audio with Serial Recovery DFU over USB CDC

Hi Omri,

I am sorry for a delayed reply. I was out of the office.

We have done some testing with regard to netcore serial recovery without external flash on nrf5340. Please have a look at unofficial netcore serial recovery with sysbuild example. Serial recovery on the netcore is not supported using only primary slots. Note that in the pm_static.yml file, you need to have mcuboot_secondary_1 partition which has the same size as mcuboot_primary_1. In addition, you need to ensure that mcuboot_secondary_1 partition overlaps with mcuboot_secondary partition by choosing the same start address.
Please let me know if this helps in resolving the issue.

Best regards,
Dejan

Hi Omri,

I have reached out to our developers again. We will further look into this issue. I will get back to you as soon as I have some relevant information, probably during this or next week.

Thank you for your patience.

Best regards,
Dejan

Hi Omri,

Regarding shifting hex image, I have discussed your question with our developers. Shifting of hex files manually is tedious work, which is prone to errors, i.e. it is easy to do it wrong. It would be much easier if you could just build your application using sysbuild. However, this is not possible at the moment as you already know from the Case ID: 328874. It is recommended that you wait for the resolution of the case 328874.

Best regards,
Dejan

Hi Dejan,

First, I'm looking for serial recovery solution and not FOTA solution.

Second, the solution with Sysbuild return a build error as in Case ID: 328874, so I'm looking for solution without Sysbuild configuration.

The main problem with that approach, that in NCS v2.7.0 I can not build the IPC Radio as part of the nrf5340_audio application without the Sysbuild.

The only thing I can do is to build it without Sysbuild as standalone and that's what I did.

I build the nrf5340_audio application with serial recovery without sysbuild and flash the image to the nRF5340_Audio_DK app core.

After that I flash the IPC Radio standalone image to the network core.

Everything works fine.

The problem in that solution is that I can update only the application image and not the network image in serial recovery mode.

My suggest is to try to do the same as in NCS v2.5.0, the nrf5340_audio application will create empty network core with B0N and then take the precompiled IPC Radio HEX image and merge it by ble5-ctr-rpmsg_sign.py script.

The problem is that I can not merge the IPC Radio HEX as is. I need to shift it in order to merge it.

As in NCS v2.5.0 there were already precompiled shifted images:

ble5-ctr-rpmsg_3393.hex - regular build,

ble5-ctr-rpmsg_shifted_3393.hex - shifted build

and ble5-ctr-rpmsg_shifted_min_3393.hex - shifted build with min b0n flag.

is there any guide how to shift HEX image so i could create shifted hex from the IPC Radio HEX?

Regards,

Omri

Hi Omri,

It is not intended for ipc_radio to be built as a standalone application. There is a discussion which could provide some information how to use FOTA in audio application in NCS v2.7.0 - audio sample with FOTA.

In general, to enable net core updates, application should be built with these options:
-DSB_CONFIG_SECURE_BOOT_NETCORE=y
-DSB_CONFIG_NETCORE_IPC_RADIO=y
-DSB_CONFIG_NETCORE_IPC_RADIO_BT_HCI_IPC=y
-DSB_CONFIG_NETCORE_APP_UPDATE=y
-DSB_CONFIG_BOOTLOADER_MCUBOOT=y
Secure boot for application core can be disabled using
-DSB_CONFIG_SECURE_BOOT_APPCORE=n

You can find more information in configuring b0 bootloader, secure boot, enabling images and adding immutable bootloader.

Best regards,
Dejan

Hi Dejan,

I saw that sample and I succeeded to build it without the sysbuild, but when I took the configuration to the ipc radio application, the build failed.

How can I merge the network core bootloader sample configuration with the ipc radio application?

Should I create child image in the ipc radio application with mcuboot.conf file that includes the network core bootloader sample configuration?

regards,

Omri

Hi Omri,

[quote user="Omri"]I tried several configuration like add CONFIG_BOOTLOADER_MCUBOOT=y or CONFIG_SECURE_BOOT=y to prj.conf but it failed.[/quote]

You could look at the network core bootloader sample which can update the application firmware on the network core.

Hן Dejan,

I use NCS v2.7.0 and I succeeded to build the ipc_radio without sysbuild as you recommended.

But I need the ability to update the network core so I tried to build the ipc_radio with bootloader.

I tried several configuration like add CONFIG_BOOTLOADER_MCUBOOT=y or CONFIG_SECURE_BOOT=y to prj.conf but it failed.

Can you please send me the exact configuration for ipc_radio application with bootloader?

Regards,

Omri.

Hi,

For example, if you use NCS v2.6.0 and look into ipc_radio application. you could build it using this command:
west build -b nrf5340dk_nrf5340_cpunet --no-sysbuild -- -DEXTRA_CONF_FILE="overlay-bt_hci_ipc.conf"

How can I build the IPC radio (SoftDevice controller) without sysbuild?

Hi,

The issue has not yet been fixed in the ticket with Case ID: 328874. You could try to use serial recovery without sysbuild for now.

I'm using a board based on the nRF5340 Audio DK, but without the peripherals like LEDs, buttons, HW codec, SD-Card and external flash.
