nRF5340 audio application FOTA problem with latest SDK

[muli]

I am building and testing the nRF5340 audio application from the latest SDK 2.6.0 and trying to get FOTA updates working by following this guide : 

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.6.0/nrf/applications/nrf5340_audio/doc/fota.html

When I try to build the image for flashing, even for just the app core as follows :  buildprog.py -c app -b release -d headset -m internal , I get the following error : 

Traceback (most recent call last):
  File "C:\ncs\v2.6.0\nrf\applications\nrf5340_audio\tools\buildprog\buildprog.py", line 498, in <module>
    __main()
  File "C:\ncs\v2.6.0\nrf\applications\nrf5340_audio\tools\buildprog\buildprog.py", line 384, in __main
    raise Exception("DFU arguments only accepted when using controller: " +
Exception: DFU arguments only accepted when using controller: ACS_nRF53. Please use standard tools.

How to solve this? Thanks

Hi,

Could you try to add the following configs in the child_image/hci_ipc.conf to reduce the size:

CONFIG_BT_ISO_CENTRAL=n
CONFIG_BT_ISO_BROADCASTER=n
CONFIG_BT_ISO_SYNC_RECEIVER=n
CONFIG_BT_PER_ADV_SYNC_TRANSFER_RECEIVER=n
CONFIG_BT_PER_ADV_SYNC_TRANSFER_SENDER=n

and this command to build for DFU?

$ west build -b nrf5340_audio_dk_nrf5340_cpuapp -p -d headset_dfu -- -DCONFIG_AUDIO_DEV=1 -DCONFIG_AUDIO_DFU=2 -DCONFIG_MCUMGR=y CONFIG_BOOTLOADER_MCUBOOT=y

Hi Amanda Hsieh 

When I try to build using the mentioned command, I get the following error. Even when I delete the build folder initially. The thing is, I have extra code added to the receiver application to advertise, allow a connection, and received commands over NUS. This all builds fine when using the buildprog Python script

Hi, 

I cannot find this line "#include "dfu_entry.h"" in the https://github.com/nrfconnect/sdk-nrf/blob/v2.6.0/applications/nrf5340_audio/src/bluetooth/bt_stream/broadcast/broadcast_sink.c. Please make sure the files from v2.6.0 nrf5340_audio application.  

If you use VS code to build the code, you have to add the overlay/configs to the build configuration manually if you have extra settings.
