    GPIF to USB DMA Manual channel don't work

    l312361206_3478106

      Hi,

       

           I am using GPIF to transfer data to USB.

           Now if i config the dma channel as auto mode, the channel work well. But when i config the dma channel as manual mode, add the prob notification and callback. I cant see the callback has been called.

           The size of dma is 15KB and the count is 8 .

           Anyone can give me some ideas the reason?

       

      Thanks a lot!
