DaVinci MUSB controller with CPPI DMA

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I am doing development for some Audio USB device on TI's DaVinci DVM 6446 board. I am using MVL 2.6.10_mvl401 kernel. Being it USB Audio device, it does ISO transfer and this apparently doesnt work if I have CPPI DMA enabled.

I know there have been lots of work happened post 2.6.10 kernel and there are certainly many bugs when you enable CPPI DMA. I just would like to know if someone tried to *backport* all recent fixes to 2.6.10.
Anyone from MV or TI ? Any help would be appreciated.
