AVB-LC mode of operation

Post by vinaykmurthy »

Hello All,

Need your opinion on using the XMOS AVB as an endpoint in AVnu's automotive profile.

I want to verify whether my switch (running AVnu's automotive profile) is capable of handling the audio packets sent from the XMOS device. Since the XMOS-AVB-LC is a certified AVnu product, is it possible to configure it to run in AVnu's automotive profile ?

If so, are there any suggested changes in the software which needs to be done to rebuild the image ?

Thanking you,
Vinay

If you rebuild the LC firmware configured for with an automotive profile then it will no longer be the certified firmware. However, if you wish to do this then a good starting point would be the following Application Note which describes how to optimise the AVB startup time:

If it's helpful, the description of the AVB Automotive Profile is here:

Hello,

I also want to built up an automotive AVB environment. The AN00111 shows how setup up the environment more static. To do this i need the belonging SW, but i can only find the PDF at xmos.com.

Does anybody knows how to get the software for better start up performance?

Let me take a look at this... There's no reason why this shouldn't be published

Hello,
thanks for your reply.
On https://www.xmos.com/support/appnotes/AN00111 I can only find the PDF, not the according SW.

The AN says:
Required tools and libraries
Start-up time optimized modified source files, to augment version 6.1.1 of the AVB Endpoint soft-
ware. These are included in this application note.

Ok, it seems there is an issue with our app notes process where only a complete application's source can make through the publishing process.

AN00111 has source which modifies two libraries and an app, but doesn't have the whole AVB (now called TSN) library. So the idea was that you get a working workspace with the demo app and copy over the the modified file/directory tree.

Anyhow, while we work out how to modify this, please find the zip of the src files. This may be removed as and when publishing it through the app note release flow is addressed.

We have published an improved version of the 1.0.2 of the AN00111 Optimizing start-up time in AVB endpoints.

PFA the corresponding source files.
