    Hi Anant,

    Once I did the same for OMAP-L138 processor in WIndows CE 6.0.

    You need to make sure that the Pixel Clock, HFP, HBP, HSA, Lines Per Panel, VFP, VBP, VSA, Pixel Per Line are taken care for new LCD in the LCD controller.

    Apart from this if there are any enable signals for power you need to make sure to drive them.

    Regards,

    Hi,

    Thanks for your reply,

    Actually I have made the changes and its working fine , except there are some random exceptions in random application/modules and system crash.

    if I remove the display driver from osdesign everything works fine. so I suspect display driver is the culprit for corrupting the memory or something similar.

    So I thought if there any document regarding porting I can insure the changes I have made. or I could correct if there is anything other than core lcd changes, I mean any special memory or similar requirement. may be the osdesign/component dependancy

    Thanks,
