Hi folks, I am trying to enable the whole musb HS DMA code on Blackfin. But found the is no place to clean the DMA interrupt flag in musbhsdma.c. As a result, the irq always happens with the same DMA irq source. I add some code to clear the DMA interrupt. Did I miss something here?
After enabling the musb HS DMA code for Blackfin, normal operation is OK for mount/umount U-disks. But when I tried to write large file to the U-DISK (such as 10Mbyte or 100Mbyte), speed is very slow and mush slower than PIO mode, IMO. Did you guy meet this issue before on OMAP?
