Sorry for the Offtopic too, but aint source code available at the samsundforum? Do the source contain the needed drivers for the linux kernel? I thought only the exeDSP is not open source.

I explain the technique...

For change bootlogo, you needed to leave Bootup logo ON from menu. Because TV setup some eeprom values with it. Without this, TV cannot show any bootup logo.
Than you needed to place a file to /mtd_rwarea/FastLogoOff for disable original boot picture load.
After that, you can show any ARGB 32 bit BMP file by loading FastLogo kernel module from "start.sh".
Addition of this line will make the job.

Code: Select all

 insmod /mtd_exe/FastLogo/FastLogo.ko logo_file=/mtd_rwarea/mylogo.bmp pos_x="0" pos_y="0"
File could be any file size up to FULL HD resolution.

But do not try this at home. Even I bricked my TV while playing with start.sh file. So this is DANGEROUS.
But saves you play with more dangerous things like flashing custom partitions. :twisted:

Erdem, you forgot to say, it is for D5 and D6 series only and it is neccessary to add all environment variables there and sure start exeDSP from start.sh.
Chmod 755 is needed also! Wrong start file is direct way to brick.

If interested i could post working start.sh (separate thread).

I see also "/dtv/usb/sda1/SEC_LOGO" string in the FastLogo.so, what does it do?
(I'm just looking at the contents of the FastLogo.so file, not disassembling...)

It's interesting. But I bet it's useless. Because when that script shown at boot up, even some internal partitions doesn't mounted. I don't think if usb disk mounts. Probably those are some development test case strings remains at ko..

Hello together!
I'm really exited I just got SamyGo to work on my D7000 - I'd never thought that would ever happen. Great work and thank you very much!
Now I also wonder whether it's possible tho change the boot-Logo or even the background-image in Smarthub. Any news about this?

Cheers,
Manu
