Using OMAP-L13x as a USB Audio device

Other Parts Discussed in Thread: OMAP-L137

I know MSC and HID devices are supported by the (in)famous close sourced Jungo stack. Does TI offer anything for audio? Does TI have plan to do that?

One of the main application areas of OMAP-L137 is professional audio, but the support looks hlaf hearted.

Sorry, this is not available for the DSP. Supported USB modes can be found in the User Guide for PSP 1.30.01 for the c6747:

For the OMAP-L137 we expect you to leverage the rich ARM/Linux ecosystem where the USB isochronous driver and many others are available for use. This is detailed in the Linux PSP Features and Performance Guide:

Would the DaVinci PSP work on OMAP-L137? Do they have compatible peripherals, e.g. USB and McASP?

It would be great if TI can provide a walk through on porting the USB Isochronous Driver from DaVinci to OMAP-L1. I am sure a lot of people would appreciate that.
