Have you seen the work done at Denx (www.denx.de) with the MPC5200 and 
SM501?

Hello, Mark!

Sorry, for my late reply, I wasn't reading the mailing lists for a while
because I am pretty busy with hardware development.

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. :-)

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.


Best greets,

Hello, dear list members!

This is my first mail here, so hopefully, everything works fine...

We at Anagramm GmbH, located in Germany/Munich, are planning to setup
an embedded system for our new image grabbing/camera platform
utilizing the Freescale MPC8540 (PowerQUICC III) processor.

I am planning to use tested hardware components for the first
prototyping setup to concentrate on getting things going without
worrying about broken HW. The goal is to get a portable
solution with fast interfaces for about 10..50+ MBytes/s throughput.
(Local Bus Bulk Data/IO or RapidIO or GPIO to Gigabit Ethernet)

Additionally we want to add up an interface for a small TFT Panel.
I think about putting a Silicon Motion (SMI) Graphics controller (SM712 
or SM501) on the PCI bus. I am already in contact with SMI about HW/SW 
support from them.

I think about porting some old xfree drivers from SMI to a current
2.4 or 2.6 kernel or writing a framebuffer device driver for the 
graphics. Is there anybody with a similar setup and/or some similar 
tasks to get Linux with X11 to work on targets like this?
Later on we want to port our image processing environment and
a Qt-GUI to the platform for some products.

Best greets,

Clemens Koller
