Please read the U-Boot documentation <http://www.denx.de/wiki/DULG/UBootSplashScreen>

btw u-boot 2009.08 is very old. it#s recommend to use the current release.

Hello Jens,
 
Thanks for your quick response.
 
Actually I tried with U-Boot latest release (u-boot-2013.01.01.tar.bz2) also.But I am not able to see the SPLASH SCREEN.
So, please share the SPLASH SCREEN image enable procedure for latest U-boot (u-boot-2013.01.01.tar.bz2) source code for i.mx53loco.
 
Thanks & Regards,

I'm not familiar with imx53loco board. But I see Splash and BMP are enabled in config.
So you need only burn you splash to flash and set the environment variable "splashimage" to the start address in flash.
You should test your splash image with bmp display <address>.

U-Boot release 2013.01.01 for mx53loco supports two LCD panels,
CLAA07LC0ACW and Seiko-43WVF1G. If you have a different panel, you
will have to add support for it. If you have Seiko panel, please set
up environment variable panel as follows:

=> setenv panel seiko
=> saveenv

and reboot, then use load a bmp file and use "bmp" command to display
it.

please read about asking smart questions [2].

So why you try to read data via tftp? How about fatload or ext2load?

As Anatolij pointed out you need to use the bmp command to display some
memory range which contains the BMP image.
To get the BMP image there you can use tftp, however your server
(192.168.1.176) seems not to provide the image (/tftpboot/lvds.bmp),
cause it runs always in timeout.
Just my 2?, sorry, I can not help you with the i.mx and lcd setup.

Best regards

This is already part of include/configs/mx53loco.h

Please post your changes in the format of a patch so that we can
understand exactly what you are changing.

Also, please make sure that the backlight is turned on.

On my previous email the mx53ard code I pointed you to uses PWM to
drive the backlight, you could simply use a GPIO instead.

I've never used mx53loco board, also I never used a hannstar
display. The proper support for it is missing in U-Boot.

Also please restrict the line length in the email text to max. 72
characters and do not top post. Thanks!

Did you set "panel" environment variable to "Hannstar-XGA"
and saved the environment ? You are adding a check for it in the
board code, you also have to set this variable and save it to
the environment, then you have to reset the board so the new
setting will take effect.

Why do you add CONFIG_SPLASH_SCREEN_LVDS here ?
This configuration option is not available anywhere,
at least in mainline U-Boot code.

Your extensions are not enough, I'm afraid. You probably also have
to configure the pin mux for LVDS interface, enable the backlight
of the display, configure the backlight intensity, etc. I'm not
familiar with mx53loco, I cannot guide you what is all needed
to make video support over LVDS working. Please read the schematics
of the board and mx53 manual and make sure you understand what
is needed to configure LVDS interface and backlight properly.
Then add appropriate code.

Why are you trying to load the bmp file from network then?
Do you have a working tftp server for this purpose?

If you have the bmp files on the SD-card, then you have
to use appropriate commands to load files from the card,
like "mmc rescan", "fatload mmc 0:0 <addr> <filename.bmp>"
or similar. Only after the file has been successfully loaded
to the address <addr>, you can use "bmp display <addr>"
command.

Why are you trying to load the bmp file from network then?
Do you have a working tftp server for this purpose?

If you have the bmp files on the SD-card, then you have
to use appropriate commands to load files from the card,
like "mmc rescan", "fatload mmc 0:0 <addr> <filename.bmp>"
or similar. Only after the file has been successfully loaded
to the address <addr>, you can use "bmp display <addr>"
command.

If you connect the CLAA WVGA panel to mx53loco, the penguin logo and
U-boot version will be displayed by default.

LVDS panel has not been added yet, and that should be a simple task.
Please refer to the mx53ard board in FSL U-boot:
http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/tree/board/freescale/mx53_ard/mx53_ard.c?h=imx_v2009.08

Basically you need to pass the LVDS display timings, setup the LVDS
clocks and register the LVDS panel with the correct color format.

And please post your patches to the list once you add the LVDS support :-)
