Hi,
this is always an interesting subject, isochronous with USB DMA, and I know a good amount of patches have been made for this.
A customer is using current Beaglebone Black with the Ubuntu L3.8 kernel e.g. from here
http://elinux.org/BeagleBoardUbuntu#BeagleBone.2FBeagleBone_Black
and they are running into issues with UVC class and isochronous, when using DMA mode.
On the other side we have just released the latest SDK7 with L3.12. Could you let us know what known issues there may be with isochronous and DMA mode for the SDK7 and whether we have this fully tested?
Could you let us know what possible issues we may run into with the L3.8 from the above, potentially not having critical patches?
Thanks,
