OneNAND Cache Read Operation
Hi
I finally got around to trying OneNAND Cache Read Operation.
I got the same results as you. Just a 1 - 2 % increase in speed on OMAP3. It seems that the OMAP memory controller (GPMC) is not capable of transferring the data from bufferRAM fast enough to achieve the maximum OneNAND read speed.

Yes, it's right.
For more. OneNAND has Block synchronous read. It reads whole block at a time. but there's no performance gain compare to read-while-load at least in OMAP.
