Geode GX - Video Driver - QVGA 320x240 - Help

[Ricardo do Valle Flores de Oliveira]

Hi,

Anyone may help me, please?

I've trying to setting up a GX to works with a QVGA TFT (320x240), but i get
some problems.

To TFT works fine I neet a DotClock = 6.4Mhz, i looked in the Databook and
get the Fout formula to Dot Clock, and set up the registers to this values:
NDIV=10, MDIV=9, PDIV=3, DOTPREMULT2=0, DOTPREDIV2=0, DOTPOSTDIV3=0.

But when i looked on the board with the scope I get a DotClock=5,1Mhz.
I tried a lot of numbers configuration, but always get the same value.

I trying to configure the geode framebuffer driver from linux kernel to
works with this QVGA resolution.

Thanks a lot,
