MX53 u-boot Splash Screen support

JohnBirch — Fri, 23 Sep 2011 19:27:13 GMT

The folowing is from uboot_mx5x.pdf (in BSP MX53-L2.6.35_11.05.01_ER)

5.5 Splash screen support

Splash screen is off by default. If need to show a splash screen on lcd panel, you should add it yourself.
1. In config file, enable splash screen.

Add:
#define CONFIG_SPLASH_SCREEN
then splash screen feature is now enabled.

2.How to change splash image.
Currently, we use converted image in board/freescale/common/fsl_bmp_600x400.c.

In order to change splash image, user need to:
•Prepare an bmp image for display, better to be 600x400. Other resolutions need to modify more source.
•Convert it to .c file. Pls ask us for bin2txt.py.
•Put converted bmp.c to board/freescale/common/fsl_bmp_600x400.c.
•Modify Makefile to build it.
e.g.
COBJS-${CONFIG_VIDEO_MX5} += my_bmp.o

Hi John:

I would like to request a copy of your bin2txt.py code please.

Thanks for the info, I didn't even know that pdf for spalsh screen existed, THANKS.

I'll let you know how it worked out on mx53loco QSB

I really appreciate your reply, I am trying to get ltib downloaded.

BTW there is an 'mtd-utils' error in ltib 1st time on ubuntu 10.10-11.04

a fix:

Hi John:

Thanks for your reply,

The CONFIG_SPLASH_SCREEN option didn't display anything on mx51evk-babbage board or mx53-loco-QSB.

Could not get ANY splash screens to work on any interface on mx53loco or mx51evk using ltib uboot 110501.

BUT the factory diag tools worked.

The web factory OBDS tools came pre-compiled and the 201050_mx53_sbrth_lcb_release.bin works on mx53 QSB

But CAN'T compile this factory diag code successfully . I read the manual and tried their make instructions.

LTIB and u-boot compiled OK though.

I added #define CONFIG_SPLASH_SCREEN in include/configs/mx51_bbg.h just above line #ifdef CONFIG_SPLASH_SCREEN

make clean mrproper...

Tried it on mx51 evk babbage board, mx53 loco (QSB) boards.

This LTIB uboot did not display anything on either board.

I added a message to print in u-boot console to verify option is on:

U-Boot 2009.08 (Sep 26 2011 -11:29:27)

...Enabled CONFIG_SPLASH_SCREEN, CONFIG_LCD ...

In summary the CONFIG_SPLASH_SCREEN option did not work on mx51evk babbage or mx53 loco QSB boards

No display anywhere.

What DID WORK was the binary from 201050_mx53_sbrth_lcb_release from freescale website.

I copied this to mmc sd and it worked on mx53 vga and tft display (the 7" for mx51).

Any help would be appreciated.

Thanks in advance,

Jerry Fat

Where is the config file on i.MX53-QSB ?

Re: MX53 u-boot Splash Screen support

JerryFat — Mon, 26 Sep 2011 18:48:32 GMT

Hi Eduardo:

Which config file ?

I installed ltib110501 from tarball (./install ./ltib -c) and then installed u-boot:

./ltib -m prep -p u-boot
./ltib -m scbuild -p u-boot
./ltib -m scdeploy -p u-boot

I added #define CONFIG_SPLASH_SCREEN to (u-boot) include/configs/mx51_bbg.h just above line #ifdef CONFIG_SPLASH_SCREEN

to manually build u-boot in ltib freescale uboot ltib board files :

cd /ltib/rpm/BUILD/u-boot2009.08
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- clean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- mrproper
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- mx53_loco_config OR
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- mx53_evk_config OR
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- mx51_bbg_config IS "mx51evk"
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- u-boot.bin
sudo dd if=./u-boot.bin of=./u-boot-no-padding.bin bs=1024 skip=1
sudo dd if=u-boot-no-padding.bin of=/dev/sdc bs=512 seek=2
sync

U-boot comes OK up but no splash screens...

Hello Jerry,

My question was about config file to put this line

#define CONFIG_SPLASH_SCREEN

I'm using i.MX53-QSB

In case you want to use splashscreen on mx53qsb running mainline U-boot, I just posted support for it:

much appreciated to share your work here.

Hi Leon,

I have submitted all the mx53qsb framebuffer patches to the U-boot list, but in order to help people to test it I created a branch (u-boot-fb) here:

https://github.com/fabioestevam/u-boot-imx

Currently only CLAA-WVGA panel is supported, but it is possible to extend the support for other panels or VGA output.

Thanks John,

I confirmed the Splash Screen operation on i.MX25 3Stack board.

When the u-boot was loaded, the Screen displayed the purple color on the full screen.

Is that right?

As the next step, I want to change the display Image.

Could you give me the converting script, bin2txt.py?

And Could you tell me how to use the script?

Best Regards,

Eric.

Hello John!

Tried to get u-boot splash on my MX53 and it works perfectly!!!

Can you give me the mentioned bin2txt.py script to convert my own splash screen? Is there a limitation of the image size? I use an 1024x768 screen.

Regards,

Rooney

Hello John!

Thanks for the script!!!

Can you please explain which format the bmp file need to have? Can't see my own splash screen...

Resolution = 600x400

Colors = ? --> 16 Bit, 24, Bit, 32 Bit, indexed?

Regards,

Rooney

Re: MX53 u-boot Splash Screen support

JohnBirch — Fri, 30 Nov 2012 19:17:29 GMT

it is eaier to make the image 600x400, other resolutions need to modify more source (see uboot_mx53.pdf section 5.5)

As for the bits per pixel, you should match that to your display, we typically use 16bpp.

Re: MX53 u-boot Splash Screen support

fabio_estevam — Fri, 30 Nov 2012 22:29:38 GMT

Rooney,

I suggest you to use the mainline U-boot as it has splashscreen turned on by default for mx53qsb.

If you need to create your own splash screen:

Re: MX53 u-boot Splash Screen support

JohnBirch — Tue, 25 Jun 2013 20:29:13 GMT

I haven’t personally gone through this, actually.

What did you try?

Did you do the following, as described in section 5.4 of the uboot_mc6x.pdf?

5.4 Splash screen support

Splash screen is off by default. If need to show a splash screen on lcd panel, you should add it yourself.

1.In config file, enable splash screen.

Add:

#define CONFIG_SPLASH_SCREEN

then splash screen feature is now enabled.

2.Boot into u-boot console and set splash screen enviroment variables.

setenv splashimage ‘0x97c90000’

setenv splashpos ‘0,0’

setenv lvds_num 1

Note:

splashimage is the image address that will be loaded.

splashpos is the image position that will be displayed.

If you want to use lvds0, then set lvds_num to 0.

3.How to change splash image.

Currently, we use converted image in board/freescale/common/fsl_bmp_600x400.c.

In order to change splash image, user need to:

•Prepare an bmp image for display, better to be 600x400. Other resolutions need to modify more source.

•Convert it to .c file. Pls ask us for bin2txt.py.

•Put converted bmp.c to board/freescale/common/fsl_bmp_600x400.c.

•Modify Makefile to build it.

e.g.

COBJS-$ += my_bmp.o
