Latest nrf5340 audio dk firmware not working

[sridhar j]

Hi,

I am using firmware at https://github.com/nrfconnect/sdk-nrf/blob/main/applications/nrf5340_audio/bin/ble5-ctr-rpmsg_3310.hex in network core of nrf5340 audio dk and using app core with hci_uart at 1M

HCI uart response is not coming for hci reset command from external host.

The same is working for ble5-ctr-rpmsg_3251.hex firmware.

What else do I need to configure?

Does this happen whem HCI_UART boots up? Or does it work for a while with just no response from the reset command?

Is you are stuck on boot, please check if you CONFIG_BT_HCI_VS_EXT=n is added to prj.conf.

The reason why we need to disable the HCI vendor specific command is because that is for the Zephyr controller. There is a conflict between Zephyr HCI VS and PCFT HCI VS.

If it can work for a while just no response from reset command, then it would be great if you could share the HCI traffic and how to replicate the issue, so we can check it.
