Hello,

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. IN our board the LCD controller ChipsSelect is connected to the Static Chipselect 4 of PXA255 The LCD is a 16bpp LCD.

We are able to initialise the LCD. We are able to get the plain colors sucessfully. We are trying to display u-boot logo on this 16bpp LCD.But it is not displaying..

When we looked at code bmp_logo.c , we found utility called bmp_logo, which converts bmp file into header This header file is for 8 bpp & has a bmp palette field. It tries to write the Pallette info on to Palette Ram of PXA255.

But our LCD controller is external & doesn't have pallette RAM.It only has a standard DisplayRAM The 16 bit colors which this controller supports doesn't have the Pallete information.

How can we display the logo of 16bpp color depth image onto the LCD.in U-boot?

Thanks Reagrds Praveen

In message 001301c50df7$99e60900$0400a8c0@praveenvs you wrote:

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..

What is not clear to you? As you can see in your log the LCD device has been registered as an output device, and input and poutput are directed to the serial port. So everything looks perfectly fine to me. What did you expect?
