I am using imx6q usb as device controller. I configured end point 2 as isochronous out by writing appropriate endpoint control register. I am playing 44.1khz, 24 bit, stereo,wave fil;e from Windows media player.( bInterval set to 1 ms). In the device side I have performed the following steps.
- Prepare dtd with a 272 bytes of buffer
- Link dtd with isochronous out dqh.
- prime isochronous out end point.
But we do not see iso out endpoint completion interrupt. Please let me know if I am missing something.
Thank you in advance.
