lib crashes during device discovery

[uwekirst]

I'm having an issue where the avdecc-lib crashes when an avb device is found. The last output in the console window says: [NOTIFICATION] (END_STATION_CONNECTED, .. Any ideas? thanks, uwe

[andrew-elder]

That's weird - not seeing that issue here. Are you able to share what end station is on the network?

[uwekirst]

No because it's still under development. The issue disappears if the end station does not connect to other avb endstations during powerup.

[ahogen]

We've seen this kind of error if the AEM isn't valid. (E.g. AEM stated there were 2 clock sources, but configuration only provided 1 clock source descriptor).

This crash didn't appear in the Linux cmdline app (not sure about Mac). @uwekirst, maybe try the Linux version, even if it's just in a VM, to see if you can discover your devices?

Or @andrew-elder , you may be able to replicate what we saw on an XMOS board by changing this line from 2 to 3, creating an invalid AEM.
