ATAPI driver

Started by Vincent Maillard August 26, 2003
Hi all,

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??
