Rockbox Development > New Ports
porting RockBox to a Mp3/MP4 player with Manufacturer's cooperation

Oh. I can't speak for anyone else but myself of course, but I would guesstimate a fair hourly fee is around 100USD and given that HW and docs is available (there don't seem to be any public data sheets for those telechips MCUs) a two week period full-time should probably be good to get a first version there.
The problem would probably be more to find someone who's skilled enough and able to get two weeks off from what they're doing now to work on something like this.

That page is meant to describe how to reverse engineer foreign hardware, in a generic way. All targets of course need their own specific approach and there's no way a simple wiki page can include all those details.
If you have the docs and code to read as reference, there is no need to follow or even read that NewPort wiki page.

rockbox.org is loaded with info, the source code is there and we have a very living developer community on this forum, on the mailing lists and on IRC. It would simply be a matter of diving in!
linuxstb:
I agree with Daniel's earlier suggestion that the manufacturer should offer to donate some players to Rockbox developers - this would be a lot cheaper than paying for development time.
I for one could be tempted to work on it by the offer of a free device, but can only do it in my spare time, and wouldn't be able to commit to any definite timescales.
Donated devices, along with the source code to the existing firmware, schematics of the hardware and datasheets for the used components would make a Rockbox port as easy as it ever can be.

These should not be much of a problem. Manufacturer is interested to know what can rockbox do to these players. Interface aside, current firmware allow it to play mp3, wma, mp4 (after software conversion to 280x220 24frames), macromedia flash, 2 build in game (Russia square and push box), OTG transfer, FM transmitter/FM radio (depending on model), mp3 recording..
Would rockbox allow the player to do these functions as well as some new functions?

100USD/hr is way too much for us to pay for. However, we can probably offer some other incentives which might allow you to earn even more $$ (but you put some work on it to earn the incentives...)

Because if they could reuse their existing bootloader, and write wrappers around the existing driver code, a port would probably not take very long. Though I don't think many companies would be willing to give away their source code (or even able if the code was licensed from a vendor).

Well, I am confident that I can get you the current source code, however, I am not sure if the current source code can be released publically.

Some of those functions listed are not yet offered by Rockbox (video, USB OTG, fm transmit), but on the other hand Rockbox offers a lot of more functions than so.
I guess this page could shed some light on what current Rockbox can offer:
