RockChip mp3/mp4 players
rosco_pc:
What I found is that it was ARM + some DSP core clocked at 100 MHz.
Getting the DSP core and the other integrated functions (like sound codec/USB) to work without datasheet will be very difficult without.
Blitz:
yeah its a rock chip. i found out when i connected it to my computer. does anyone know where i can find the games .rkp, ive googled it but cant find it. also whats the screen size in pixels? (if anyone can figure it out) the strange thing is it seems to be begging you to create an updated firmware for it, it has a firmware updating software ready and everything even tho theres no upgrade.
PS: is 100mhz sufficient to run a gameboy color emulator?
gnu:
Yes, 100 mhz is enough (it really depends on the screen size and on how much the emulator is optimized: rockboy runs on 75 mhz ipods). But I don't think that has much to do with a new port ;)
Blitz:
well by googling rockchip datasheet i managed to find two juicy tidbits on an mp3 player forum:
this is a site holding just about all rock chip firmwares: http://translate.google.com/translate?u=http%3A%2F%2Fdrivers.21tx.com%2Fdigi%2FTeclast%2F&langpair=zh%7Cen&hl=en&ie=UTF8
and this one is a download for a firmware creator for the rock chip.

I'm at school right now so I'm having to minimize windows every five second to avoid getting caught (i'm in computer class) but i'll experiment with these when i get home.
rockchipper:
Anyone found anymore on the Rockchip RK2606 or RK2608.
If the chip does have an ARM9 Core, then is there a way to create our own firmware to install Linux or WinCE onto the devices and start to craft our own UI and Apps, plus more importantly, since this chip seems heavy on video/audio, it should be able to handle emulators like NES and Atari 2600 fairly well - one would hope.
I found a copy of the datasheet if anyone is interested.
Rock On !!!
