Hi Reskyllr,

Thank you for sharing your configuration. It is good to hear that you managed to find working configuration. With your current configuration that supports BIS, how much space on the flash has been used?

Best regards,
Dejan

Hi Reskyllr ,

I hope you don't mind sharing how you managed to solve it.

Could you share the configuration you used?

Thanks,

Ahmed

Hi,dejans,

I've fixed the problem and now it works smoothly, albeit with flash woes.
It is hoped that the size can be reduced as soon as possible, because adding the CIS function is obviously unrealistic at present.

Best regards,

Hi,dejans,

This is valid and can be compiled successfully, but SMP broadcasts will not be created successfully, which is necessary for FOTA:

Hi,dejans,

I've tried these settings:
CONFIG_BT_ISO_BROADCASTER=n
CONFIG_BT_ISO_SYNC_RECEIVER=n
If these settings are applied, PA synchronization will not be possible.

Are there any other config settings I can try?

I use CONFIG_AUDIO_DFU=2,In NCS2.4.0,We have mass produced.

Hi all,

Reskyllr, there are some configuration options which you could set to avoid flash overflow.

CONFIG_BT_ISO_PERIPHERAL=n
CONFIG_BT_CENTRAL=n
CONFIG_BT_PERIPHERAL=n

[quote user="Ahmed Moheb"]Can you propose the required configurations for an ISO peripheral device that would receive a CIS ISO stream and send it again as BIS ISO stream while supporting the FOTA operation.[/quote]

In addition to CONFIG_BT_CENTRAL=n, try setting CONFIG_BT_ISO_SYNC_RECEIVER=n.

Best regards,
Dejan

Hi dejans

Thanks for the clarification and sorry if I miss understood the goal of your questions.

I don't want to take the discussion in another direction, but I think it may help.
Can you propose the required configurations for an ISO peripheral device that would receive a CIS ISO stream and send it again as BIS ISO stream while supporting the FOTA operation.

Thanks in advance,

Hi Ahmd,

[quote user="Ahmed Moheb"]As I'm facing the same problem, it's clear from the begining that it's not an issue with the FOTA operation itself, it's about the size of the generated binary of the SoftDevice controller.[/quote]

I agree that the problem is with the size of the binary.

[quote user="Ahmed Moheb"]

Reskyllr is asking about which configuration options can be disabled to reduce the size of the SoftDevice controller image without breaking the broadcast usecase for GW/HS.

This is totally independent of whether you are building the application CONFIG_AUDIO_DFU=1 for single image or CONFIG_AUDIO_DFU=2 for multimage upgrade

[/quote]

I understand this. My first two questions were just requests for confirmation. The main question is about the set of features that are planned to be used since this determines which config options should be included and which could be excluded.

Best regards,
Dejan

Hi Reskyllr,

Can you please confirm that you tried to do DFU on external flash?

Can you confirm that you tried to do simultaneous update of both cores?

We would need to examine configuration options based on the list of features that you intend to use in your application. Could you please specify all the features which you plan to use?

Hi,dejans,

I've tried this, I've set:

CONFIG_BT_ISO_CENTRAL=n,this is already the result after setting.
For:
CONFIG_BT_ISO_BROADCASTER=y
CONFIG_BT_ISO_SYNC_RECEIVER=y
If I set either to n, I can't synchronize with bis gateway.

For Le audio, are there any other options that can be turned off?

Best regards,

Reskyllr

Hi Reskyllr,

Can you check if 3 options shown below are set to 'n' in your output files?
# CONFIG_BT_ISO_CENTRAL=y
# CONFIG_BT_ISO_BROADCASTER=y
# CONFIG_BT_ISO_SYNC_RECEIVER=y

RE: nrf5340 audio: FOTA Firmware can't build

dejans — Mon, 29 Apr 2024 09:11:26 GMT

Hi Reskyllr,

Which features of SoftDevice Controller have you tried to disable? What was the result? How big improvement did you get on the initial overflow of 20308 bytes?

Dejan

RE: nrf5340 audio: FOTA Firmware can't build

Reskyllr — Sun, 28 Apr 2024 02:15:27 GMT

Hi dejans,

You're right, I'm definitely working in that direction.
What I need assistance with is: As the controller of Le audio BIS, what features can I disable? I have made some efforts, but the size still cannot meet the needs of dfu.

Best regards,
Dejan

I guess this is just a typo on your end, but it should be -DCONFIG_BOOTLOADER_MCUBOOT=y.

[quote user="Reskyllr"]Is there something wrong with the build instructions I use?[/quote]

Apart from what I mentioned above, build command looks fine. Currently, there is a limitation on FOTA upgrade due to updating SoftDevice on the network core in both DFU methods (single and multi-image). SoftDevice binary becomes too large to run on a network core together with a bootloader. Suggested solution for reducing the size of SoftDevice binary would be to disable unused features of the SoftDevice Controller.

Dejan

Reskyllr — Fri, 26 Apr 2024 05:48:56 GMT

Hi,

I have always used external flash,

In NCS2.4,i use buildprog.py:
python buildprog.py -c both -b debug -d headset -m external.

but in NCS2.6,the dfu firmware does not support this construct.

Is there something wrong with the build instructions I use? How should I modify it? The reference link does not specify the method.

Best ragards,

Hi,

External flash shield is needed if you want to do simultaneous upgrade of both cores. You can read about this in Requirements for FOTA.
