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
