Hello, I am very sorry that I haven't given enough information.
Our board is customised board based on PXA255 processor, in that we have the samsung Color LCD Controller( S6B33B0A) . The LCD is not interfaced to the Default PXA255 LCD pins.But it is on VLIO
In our board the IDE is on VLIO & so also LCD We are able to successfully boot from the Harddisk Now we are trying to initialise the LCD.IN our board the LCD controller ChipsSelect is connected to the Static Chipselect 4 of PXA255
We have followed the basic routine given in the u-boot source to initialise the LCD, We are giving the the Static Chipselect 4 ( CS4 ) address for lcd_base (10000000 on PXA255) After initialising we are getting the shell prompt on stdout(serial) In that when we did the cninfo we got the following.. $ coninfo List of available devices: lcd 00000002 ..O serial 80000003 SIO stdin stdout stderr nulldev 80000003 SIO
We are not sure if the lcd console info is correct..
Thanks Regards Praveen

We don't know your hardware, we don't know your driver, we don't know how you integrated it into U-Boot.
This is not even enough information for a wild guess.
