Aniseed:
i have just recieved my new iriver x20 and have decided to try my hand at getting some sort of port started. (seeing as i have about 6 months free i thought why not)

any way i have pulled apart the player but havent managed to get any scans of the PCB's or digital photos but i took down most of the details.

   model:   TCC8200
   
   other#:   OOXX-YNR-PR

        uses:     the brains i guess.

   modle:   CMS4A32LAH-75EE
   
   other#:   0647A KOREA
        uses:     from what i can gather from its position to the processor and other googled info
                      its 128 megs of quick access memory
   
Memory Chip
   make:   Samsung 652
   modle:   K9HBG08U1M

        uses:     the main memory, 4 gigs of it on 1 chip

            MC1N
        uses: far as i know, Amp and controler for headphones and the speakers on the back of the player
                  and the microphone to.

Found this http://www.telechips.com/product/p_028.htm

Some additional info on the main audio chip. From that site i would guess this does all the audio, video, immages and probably themicro sd and usb interface as well.

Hi I'm gonna buy iRiver x20 player... I can help with porting rockbox to it (Have experiences with C++, C, ASM) ... If anybody has already started porting it I'll be glad to contact him. I think the first step is to create wiki page for x20

... searching the net for useful informations about X20 chips, mainly TCC8200 for hours. And finally i found some on rockbox site (different topic, but there are links for our processor too)  :)

here is the link:
