yes its not a data sheet but there is quite useful information inside

There is no MP3 chip inside, is there? Are you talking about the DAC?

markun, our player has SA58700 that meens our player has audio codec. propably the sdram controller was pictured like it.
p.s the samsung support answered me thatthey ont have the data sheet. but they sais were can we reach it. so i will try.
here are some more parts of players hardware with specs
sensor
data sheet http://w3.tue.nl/fileadmin/id/objects/E-Atelier/Phidgets/Hardware/Datasheets/1015_-_DatasheetQT411.pdf
here is some intersting info about the sensor

in the end there is a interesting scheme
one more link about the sensor http://www.seminews.ru/sensors/141.html

There is many interesting code in SST39VF800.dfu, eq. interrupts code.

Indeed. I disassembled it yesterday. Because of the "Thumb only" error message in there I thought there would have been some Thumb code, but it's all normal ARM so far. I guess the SST39VF800 is the 1MB NOR flash included in the SA58700, what do you think?
Right now I don't really have a lot of time to analyze the disassembled files. Are you trying to figure out some register addresses etc?
btw, With DFU-Util from OpenMoko it could be possible to run code from SDRAM without flashing it, that would be really useful for development. Hopefully it works.
EDIT: just looked at the code in Blues_MSC.bin file from the dfu tools and it's very similar to the firmware updates.
