Linux on CS5530 (Geode) boards

Started by Igor Wawrzyniak March 17, 2004
Hello,

I'm working on a project of embedded Linux device.
Dhe device will need a graphics mode. The board I'll
use will probably have CS5530-based graphics adapter.
I found that it's possible to run XFree86 on it
(http://www.larwe.com/technical/geode_linux.html).
However, I'd rather stay out of X due to performance
and limited resources. I thought about using DirectFB.
Anybody tried using Linux and framebuffer on this device?
Is it possible to get a better mode than VGA 640x480/16 colors?

Best regards

How about xfbdev? http://www.esatechnology.com/linux/ That's what I use. Fits onto a 32MB CompactFlash, I run it up to 1024x768, and its X. -- Alex Pavloff - remove BLAH to email Software Engineer, ESA Technology

Yes. You can also use svgalib on this platform. VESA modes are supported up to 1280x1024x8bpp/1024x768x16bpp. However, there are issues, the bugliness of which depends on your BIOS and on what you want to do, exactly. The platform is apt to lock up (to varying degrees) if you switch from a VESA graphics mode to a text mode. As long as you go into graphics mode and never leave or change modes, you should be OK.

You may use kdrive on Geode. It's low footprint, works fine and uses the 2D accelerator. Alternatively you may use MicroWindows but with no acceleration. Regards.
Thanks for all the replies,
