Hardware blocs of the RockboxPlayer
That dev board have all that is needed unless the DAC (candidate to be TLV320AIC23) and the LCD module.
Neo1973 - Open hardware mobile phone
This is an almost Open hardware(just the GSM modules are not Open), mobile phone for $300! It have all we need plus much more :)
Highlights:
* ARM920T core, Samsung S3C2410
* 64MB NAND flash
* 128MB SDRAM
* LCD Module with Touch Screen - color 480x640
* Audio out
* microSD-Card
* Bluetooth
* USB Host + USB device
* Battery compatible with a Nokia BL5C battery

To much information, I don't know what to say.
It's very interesting, because OpenMoko is open mobile phone software stack and they make the hardware, the Neo1973, to have a way to run the OpenMoko! Looks like to me what I pretend, to have Free/Open hardware for Rockbox software.
Bagder:
Regarding the Neo1973, note that they're about to ship an updated version: http://wiki.openmoko.org/wiki/Neo1973_GTA02_Hardware
... and their dev board is a lot more expensive than 200 USD AFAIK...

No that's 200 Euro's. Probably closer to $350 US. (I forget the exchange rate but the dollar has taken a beating lately)
casainho:
I were at IRC chating with Bagder and others.
About Neo1973, I said: that hardware is much more than we need, expensive and not stable hardware, we can't control that :-( and agreed, saying: exactly - but with already existing sw, a company that sells it and an existing community.
I asked: do you have any advice for next steps? - I am lose... and he replied: yes, don't put your hopes to a company doing this
settle for a hw design and use that build-your-own style
prove that the design works and that there's working software
should put yourself in a better position when trying to convince companies
I think the very reason you don't already see companies selling products like this is because companies don't see much value in doing so
the idea isn't exactly new.
I am still waiting for an answer from http://ic-board.de/, I will just for more 3 days, after that I hope to contact Olimex and ask If they can/want to help in defining, designing, build and sell It for us, thinking in that they can upgrade their MOD-MP3 MP3 PLAYER MODULE - http://www.olimex.com/dev/mod-mp3.html
I think that until that we can continue on looking at dev boards and LCDs.

Eheh, you are right :) I am always thinking in Dollar = Euro :) - So, what is the cheapest one until now?
eumesmo:
How much easier would it be to first design a home/car based rockbox player with IDE/CF/USB mass storage/Network support? Without power considerations, would that broaden and cheapen development? Wouldn't that attract the interest of a bigger share of the rockbox community, and afterwards create momentum for open-sourced hardware developement and replacement of all personal players? Do you still need dev boards when you can etch your own boards?
