Hi Vineet,

I recommend you to use as start point for writing a lcd panel driver some existing driver and make necessary changes for your hardware. For example you could look at the ../linux-2.6.37/drivers/video/omap/lcd_omap3evm.c file.

Hi Tsvetolin,

Thanx for your reply,

Adding more information, i am using chipsee beagleboard expansion v.1 for LCD..

800*480 innolux display panel (at070tn83).

So the path u mentioned is it okay or can i look for drivers/video/omap2/

here display, dss two directories are there, and in displays different panels are there.

Hi,

In previous post I give you only an example but after analyzing the issue I think the more suitable start point would be drivers/video/omap2/panel-generic.c file.

HI,

I configured the RFBI (RFBI mode) and DISPC,

But the setting are not reflecting back on LCD.

My doubt is whether the innloux LCD display which is on Chipsee beagleboard expansion is

interacting with beagleboard-xM, how to check this one.?
