USB OTG Client as Mass Storage is Slow in DMA mode

Hi ,

I am facing difficulties in enabling dedicated DMA for usb otg. I need to expose SDcard as mass storage through the HS USB OTG .

My setup is as follows

1. EVM MAIN BOARD REVG

2. EVM 3530/37XX Processor module RevD with AM3730 processor.

3. WINCE6.0 BSP version 6.15

After enabling USB DMA, Its taking long time to mount and only some files are copied in a 900 MB folder.

i hope its is know issue since in Registry entry i have seen an entry like this "; DMA currently not working". Do have resolved this or any solution?

note: i found above comment in BSP_WINCE_ARM_A8_01_02_00 also
