porting RockBox to a Mp3/MP4 player with Manufacturer's cooperation
saratoga:
I doubt they're going to hand over any money unless Rockbox motivates a LOT of sales.
ryran:
It would motivate a sale (or buy, rather) from me and at least a couple other people I can think of.....

Hi everyone,
Well, at this stage, manufacturer seems to be willing to give free X8 player to developers who is working on it. Cash incentive maybe possible but that will depends on what developers can provide and whether manufacturer takes it or not. (e-mail me if you want better answers..)
Sorry for taking so long, at last I can supply you with the circuit diagrams for the X8 mp4 player. There is problems getting hold of the source codes because the source code mostly belong to Telechips, not the manufacturer, and they have agreements on the source code. Therefore, we are working out what we can do about it.
I can e-mail you the circuit diagrams if you are interested to look at it. However, as these diagrams are not for public release, in accepting these diagrams, you agreed that you will not release them to the general public. And if you forwarded these to any Rockbox developers, please let me know who have got them.
BTW, the mp4 reviews are not up yet. The X8 players had just been manufactured and I have yet to receive them. I intend to get a comprehensive review on the X8 player after it arrive and release the A8 and X6 reviews together. Thanks for waiting.

I also have the software for loading up the firmware, if it is useful to you, I can e-mail it to you as well.
Cheers
Eric
More info for you
OTG chip used is ALI M5637
http://www.ali.com.tw (manufacturer site)
Some info on the chip (sorry, only found chinese pages)

Update: Don't worry about the this OTG chip, my manufacturer already had complete information on this chip, the only problem is the TCC761.... ???

URGENT
The manufacturer intends to have a new project.
They would like to know if they supply all (everything you can dream of) hardware information on their machines to Rockbox, and let Rockbox do the OS development for them.
How much time (the shorter the better) and how much would it cost $$ (lesser the better) ? (they apparently can't afford much money as the cost of a 80GB model of these mp4 players easily exceed one month's salary of most people living in the manufacturer's country i.e. China)
Obviously, they would want the new firmware to be capable of all current features. (i.e Rockbox need to be able to support OTG, Mp4 playback, FM transmitter(X8)/FM radio(A8), Macromedia flash playback, etc)
And mostly importantly, would developer require any help from manufacturer's engineer? If yes, what sort of help needed.
Can interested developer e-mail me asap? Or I suggest Rockbox developers can have a group discussion before giving me confirmations on cost and time.
Thanks
Eric
------------------------------
If any developer accept such arrangements, they would definitely get their hands on source code, etc.....
For now, seems like it is impossible to get source code and datasheets as they are confidential.
The software they use to write all their software is nucleas
If you can or interested to reverse engineer the current firmware (*.bin), the Hi-A8 firmware is available here

(The A8 firmware is similar to X8, only with slight modifications. X8 firmware is not available yet.)
