Klastor MP4 players - based on Samsung chips(?)

Klastor MP4 players - based on Samsung chips(?) - possible Rockbox candidates?

<< < (2/2)

confuzled:
That's a shame - I'm not up on DSP's however would a DSP be able to drive an animated LCD and the logic in games? There are 4 in the player - snake, tetris, boxman - a sort of puzzle and road -some kind of chinese... thing.

This player also shows videos - slowly - and pictures so I would have guessed it had some kind of processor (cpu) in it and some kind of coding. There is a menu item that allows a firmware update as well.

<edit>

OK looking a bit more into this it appears to be firmware based in that the extractor - s1fwx has retrieved 'something' Here's an output trace.

disconnect from device...
success.

Well it says success, I'm not sure on all those invalid checksums, the fact that the firmware is 'too big' and that the player reports 2 firmware versions yet the extractor reports 1.

The player reports -

2011/03/14
1.0.01
2011/09/20
1712v4.0

Still I make progress? Or not?

wodz:
DSP can be very powerfull. This SoC has some general purpose core also I guess. s1mp3 players have z80 compatible 8bit core. You can try to dissasemble some of unpacked files and try to match architecture. Anyway lack of any documentation makes this port very difficult task *if* possible at all from technical point of view.

saratoga:
If it has some weird CPU/DSP you can't compile code for, you're not going to be able to do anything with it.

Jennifur:
I don't have one of these, but I did seem to find a little bit of info. The SoC in it is by Actions Semiconductor. I can't find anything more than what is on their site here http://www.actions-semi.com/en/product.aspx?id=32. You could try contacting them and ask for a datasheet.

wodz:
Thats pretty much pointless. Such requests from OpenSource/hobbiests are ignored and moreover it is likely that this is technically infeasible to port rockbox to such platform.
