Anand/Ajay, do you guys happen to have any board with rtl2.0 available for testing double buffering ? Yes we have OMAP4430 SDP board which has Mentor RTL 2.0. I am planning to send out the USB patches for OMAP4 soon. Next is to test the DMA Mode 1 patch series with and without double buffering on OMAP4. Will keep you posted on the updates.
