Subject: [U-Boot-Users] 16bit BPP color depth image on LCD
Date: Fri, 25 Feb 2005 11:23:00 +0530 [thread overview]
Message-ID: <002f01c51afe$47bf1e50$0400a8c0@praveenvs> (raw)
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
