Sorry, for my late reply, I wasn't reading the mailing lists for a while because I am pretty busy with hardware development. > Hallo Herr Koller, > ich habe heute ihre EMail > (http://ozlabs.org/pipermail/linuxppc-embedded/2004-October/015851.html) > gelesen. Hatten sie bereits Erfolg? > Ich habe ein ähnliches Problem. Wir beutzen bei uns ebenfalls einen PPC und > haben das Problem mit Big und Littel-Endian im XServer. English, please. You are looking for the SM501 graphics controller working on the PCI Bus on the MPC8540 as far as I got your mail. Yes, the last status I got is that the endianess is an issue for the X-server if the SM501 is on PCI. However there are patches for the framebuffer/X driver environment which takes care about the RGBA's somewhere out there. There are also accelerated native X drivers available but I haven't used those. Additionally, we have the option to swap the colors in hardware, just in case anything goes wrong. :-) > Have you seen the work done at Denx (www.denx.de) with the MPC5200 and > SM501? Yes. But AFAIK they have the SM501 on the Local Bus of the MPC5200 which is a different thing. Check their hardware documentation, if available. Maybe there are more updates in the meanwhile... Updates are very welcome. I will have to investigate that further if I come back to the software layer of my project.
