It depends on a lot of factors so I hesitate to speculate on actual time required. Also, "telechips" is not specific enough for me to tell how hard the arch/CPU adjustment parts will be.
But given a skilled engineer with documentation and a HW with no particular problems, I figure they could have at least a basic port working in two weeks.
saratoga:
Do they have to rewrite teh stuff from scratch? Or is the company ok releasing some of their existing code in GPL form? 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).
OT: I've always wondered if any companies look at rockbox. Seems like it would be cheaper to port rockbox to a new MP3 player then to develop from scratch, plus you'd get all the extra format support.
portable:
Do you think it is possible to port RockBox over to this mp3/mp4 player if someone is given the source code of the exisiting firmware without having the hardware itself?
We would be delighted if someone can help us port the Rockbox over or tell us exactly how to do it. The manufacturer is on our side, hence I can get you any info you need to port it over.
For more details on the product, please visit my site -- www.portable.geek.nz
For the A8 model - it uses Telechips TCC761
For the X6 model - it uses Telechips TCC721
Does it help at all if you were given the software used to load the firmware to the machine?

Well, if you know what target CPU too (I mean so that you can have a cross-compiler all setup to build with) I guess you can make a pretty good effort at least. That said, I don't think anyone would do this just for fun.
--- Quote ---The manufacturer is highly interested to port Rockbox over, the point is how do we do this? As this player is not commonly available at the moment.

Then I would say they should be prepared to pay for development work.
portable:
Well, do we have an estimated price how much it cost for this developmental work? Or instructions for so that the manufacturer can work on themselves? the page -- http://www.rockbox.org/twiki/bin/view/Main/NewPort is not that clear to me. (although I am not a programmer..)
