Hello Roman, I'm using a Lite5200B + Coral-P, to advance the development of software. Soon we will design our custom board with a MPC5200 and a graphics chip on-board. The application is not complex, but it is cost sensitive, so the Coral-P doesn't seem a good choice.
Our main need is only to have a frame buffer to draw on, but sure it would be interesting to support X11 too. You comment about a Coral-P 'successor' more adapted to big endian processors. Witch is the name of this chip? I would like to read more about it. Any other info or links you can add would be greatly appreciated, Thanks Josu -----Mensaje original----- De: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] nombre de Roman Fietze Enviado el: jueves, 11 de enero de 2007 8:49 Para: [email protected] Asunto: Re: ELDK 3.1.1: PCI Video Cards on Lite5200B Hallo Michael, On Wednesday 10 January 2007 01:09, Michael Carey wrote: > Has anyone gotten a pci video card to work on a Lite5200B board? Yes, but only the Coral-P, and X11 only correctly using a modified X server (xfree86 and xorg). The problem is the endianess. The Coral-P does not contain a byte swapper for the video memory, so it cannot be easily be used with a big endian CPU like many other grafik chips. Even the successor of the Coral-P has such a byte swapper. Our modifications to support Z-images are done in the non-accelerated driver in the shadow frame buffer extension. The Coral-P accelerated driver wasn't very stable when we tested it a while ago, I assume this very much depends on the functions you use.
