I'm developping an ATAPI driver for Sharc DSP (21161, 21065). I'm
looking for people who have done it or have a good idea to the
problem that can occur (hard, soft) with 8/16 bits devices.
I've done a test board based on a ADSP-21161EZ-KITLite board (DSP
vers. 1.1). Now I can send/receive some information with a DVD drive.
But I've some problem with some "old" CD drives (8x, 33x) when
reading data from CD drive. I must read 2x to obtain the right value.
Do someone known why??
