porting RockBox to a Mp3/MP4 player with Manufacturer's cooperation
portable:
Hi everyone,
I wonder if there will be any interest in the RockBox community to help port RockBox into a Mp3/mp4 player that uses telechips. Especially if I can get manufacturer to help to work on it. Therefore, there you won't need to do any reverse engineering or whatsoever. I might also be able to get the source code for the current firmware as well.
Reason to do this is because the current firmware the manufacturer uses is rather primitive (although it works alright). Prelimary test on the mp3 sound quality revealed that it is nearly as good as output from the computer's sound card.
Cheers
Eric

For a port to start in general, there has to be at least one (but often more) developer who owns the player and is willing to do a lot of the initial work for hardware drivers and such. Even with Manufacturer Cooperation, this would probably still be a moderately time consuming task (depending on the level of cooperation. At some point the manufacturer is adapting our software for their player instead, but then it's open source and they're free to do that as long as they honor the GPL).
That being said, I'm somewhat uncertain you'd have much luck getting any sort of agreement out of the manufacturer anyway.

People here will be glad to offer help while you port it. Ask any questions you've got. Just don't ask them to do it for you :)

We will always help new ports and porters, with manufacturer help or not. But don't expect anyone without target players to be able to do anything really technical or low-level.
IMHO, manufacturer help would be best if it included docs and a handful of players to hand out to interested existing developers.

Wow, that sounds good.
Assuming the manufacturer can devote one person who knows the player very well to work on porting RockBox into their player, how long do you expect that person to take? one week, two weeks?
