Re: [Linux-fbdev-devel] monochrome framebuffer driver on EDB9307

[gaof f. <sit...@ho...>]

Dear List,

I'm with linux-2.6.8 on EDB9307(ep93xx).
At the moment, the framebuffer driver(ep93xxfb.c) doesn't support
monochrome mode.
However, I would like to support the mode.
What can I do with ep93xxfb.c or anything else?

Thank you for your reply.
I set visual to FB_VISUAL_MONO01, and bits_per_pixel is 4.
However, I don't know how to set the PIXELMODE register and the pallette.
Any suggestion?
