Hi - I posted a question on the imx35 goup a 10 days ago, but it doesn't look like anyone reads that, so would like to re-ask it here:
http://imxcommunity.org/group/imx35xandimx35pdk/forum/topics/imx35-embedded-tt-limitations
The question is whether limitations of the embedded TT vs a real usb's TT are documented. Since posting the original question I've confirmed that I can't share iso in and out transfers in the same 1ms frame even if I reduce the number of ehci splits each requires. This means the hardware does not appear to support async usb dacs using its own TT. I'd like to know if this is a silicon limitation, or if there are any tuning parameters which may help resolve.
Thanks,
Adrian
