Booting splash screen

[BMK]

I note that newly purchased A20 Debian SD Cards have a splash screen at boot. Does anyone know how Olimex do it. I would like to change or remove this splash screen if possible.
Anyone Know how?

[santox]

the big problem here is wrong memory address. in my board the command

bdinfo

says the memory mapping starts at 0x4000000

...using this address i can load the bmp succesfully from emmc:
=>load mmc 0 0x4000000 splash.bmp

=> bmp info 0x40000000                                                                                                                                                                         
Image size    : 1280 x 800                                                                                                                                                                 
Bits per pixel: 8                                                                                                                                                                           
Compression   : 1   

anyway whe i try to display the image to the lvds connected lcd nothing is shown
=> bmp display 0x40000000

With self-built mainline U-Boot on SD card and 4.3" display it's going like:

Code Select Expand

git clone git://git.denx.de/u-boot.git u-boot-2017
cd u-boot-2017
git checkout v2017.07
scripts/kconfig/merge_config.sh configs/A20-OLinuXino_MICRO_defconfig


Modify the .config file (CONFIG_VIDEO_LCD_MODE from http://linux-sunxi.org/LCD#Script_for_automated_conversion)

Compile:

Code Select Expand

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j4

And put it on SD card:

Code Select Expand

sudo dd if=u-boot-sunxi-with-spl.bin of=${SD} bs=1024 seek=8;

Or test it via OTG/FEL injection:

Code Select Expand

sudo sunxi-fel uboot u-boot-sunxi-with-spl.bin

In U-Boot do:

Code Select Expand

$ load mmc 0:1 50000000 /bootlogo.bmp
reading /bootlogo.bmp
391802 bytes read in 51 ms (7.3 MiB/s)
$ bmp info 50000000
Image size    : 480 x 272
Bits per pixel: 24
Compression   : 0
$ bmp display 50000000

You can add this to boot.cmd, but haven't done that yet.

Edit: This does not work properly yet, linux kernel distorts the logo as soon as it boots

Get Armbian and exchange /boot/boot.bmp and you are done. At least for the bootloader.

Hi, I know that this is an old post, but "groped does not harm".
Trying this command

Code Select Expand

sudo dd if=u-boot-sunxi-with-spl.bin of=${SD} bs=1024 seek=8;gives me back:

Code Select Expand

dd: failed to open '': No such file or directory
So I tried

Code Select Expand

sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8
But in U-Boot bmp command are unknow.
Do you knw a possible solution for this or other working sequence of commands to change the splash screen?

[JohnS]

You may need SKIP instead of SEEK

[Fra]

It doesn't work.
If I use

Code Select Expand

sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/mmcblk0 bs=1024 skip=8
reboot
The boards doesen't boot anymore (the green LED reamins off) 

[JohnS]

OK - sorry.

A bootsplash can be a simple visualization of the scrolling boot messages in the console, but it can also present graphics or some combinations of both.
