MacOS - TSN/AVB Not staying selected

Postby rgilio » Mon Dec 09, 2019 10:33 pm

Hi all,

I'm using the XMOS Multichannel Board (https://www.xmos.com/products/audio/kits) and am running the TSN/AVB TDM example (https://www.xmos.com/download/AN00203:- ... .3rc1).pdf).
I've been unsuccessful with getting the example to work out of box. Essentially I'm getting to step 4 in Appendix C and every time I click the checkbox to enable/select the XMOS device, it stays checked for a quarter of a second and then unchecks itself.

I have attempted reflashing the firmware multiple times and have restarted the Mac several times as well. I cannot figure out why it's not staying connected. I'm also not getting any debug output from the XTAG when I run the application as specified in Appendix B of the tdm example doc.

Any help would be appreciated.

Hi rgilio,

I'm not familar with xTimecomposer.
But could you try use the cmd line.
The command for running the code is:
xrun --xscope bin/yourapp.xc
--xscope is the flag for displaying the debug informations.


AVB and MacOS is a very confusion matter.
The best experiences I made, was with latest version of HighSierra and Mojave.
On the other side. I use allmost avbutil.
avbutil is a virtual avb soundcard.
For example:
16 Ch In(2xSteam) | 16Ch out(2xStream)

terminal->avbutil
avbutil help
for some instructions


Please post your result.

Thanks for the response. I'll give it a shot when I've got a chance and post an update.
