823e LCD display - Microwindows

[jonb]

Hi

I have now successfully gotten Linux running on a custom 823e board,
using Monta Vista CDK 1.2, Linux version 2.2.14.  I am using an NFS
root file system and I have created a custom lsp for the board.

Our board uses the 823 LCD controller for a 640x480 TFT display.

I would like to activate the 823 LCD driver and try out the Microwindows
demo from Monta Vista, but I do not know what needs to be done.

When I configure the kernel with CONFIG_RPXLCD, I get a lot of
undefined symbols when linking the kernel, such as fb_display,
fb_default_cmap.

Can anyone point me in the right direction ?

Regards,

Jon Benediktsson

The 823 LCD driver in CDK 1.2 is a standard framebuffer device, so you
need to select some of the framebuffer configuration options.  Take a
look at the config file for the Linuxplanet LSP.

Enable framebuffer support in the kernel configuration.
