AVB demos, auto-connect not working?

jpa — Thu, 07 Nov 2024 15:35:14 GMT

In the AVB demos (GENAVBTSNUG_1.3.pdf), I'm running profile 9 & 11 on our own i.MX8MP hardware. The demo works if I manually connect the talker to the listener using genavb-controller-app, but did not automatically connect in the default configuration (fast_connect=1, btb_demo_mode=1 on listener). Further changing the configuration to:
fast_connect = 1
btb_demo_mode = 0
talker_entity_id_list = 0x49f0301020000
talker_unique_id_list = 0,1,2,3,4,5,6,7
listener_unique_id_list = 0,1,2,3,4,5,6,7

doesn't work. The listener log says "wait for new stream..." The talker_entity_id_list value is the same one I use on the talker with genavb-controller-app for the talker portion.

I tried changing channel_waitmask = 2 to = 0, but no help.

Any other general hints to diagnose issues would be greatly appreciated. I look at /var/log/avb, /var/log/avb_media_app, the journal filtered by 'avb'. But I've had other issues getting profiles 14/15 to work, for instance, and everything I see looks good, no errors, aside from the fact that I don't hear anything.

Hi,

Thank you for your interest in NXP Semiconductor products,

The DEMOs have to be manually connected as per the instructions found in the manual.

genavb-controller-app -c <talker_entity_id> <talker_unique_id>
<listener_entity_id> <listener_unique_id> <flag>

Regards
