Have a look at some of the dev boards on this site.
Prices aren't bad....

The cheap one is this, for 139$ (with RTC):

It's should be 70$ less than the: http://www.olimex.com/dev/sam9-L9260.html

Obviously based on the Cirrus EP9302:

I would prefer to go with Atmel because of the all good things that were talked previously here about Atmel. Also with that board from Olimex, since after we can contact then to make and sell the "Rockbox Player as a gadget".
I also don't have much money. I would prefer to not use now expensive LCD's, wireless modules, buttons, batteries, etc... and just make a quick prototype, to try save money and because If we can port Rockbox to that ARM9 dev board, add another LCD, touchscreen or something other, is just a question of write software drivers! Guys at Olimex can design much more complex hardware dev boards than we need!

Cirrus vs Atmel
Cirrus EP9302 is no better than AT91SAM9260. It does not have LCD i/f
see
http://www.cirrus.com/en/products/pro/areas/PA108.html#PA110_open
the ones with lcd i/f are in bga package. we might as well go with AT91SAM9261.

Well, we will just make a quick external board by hand. We can copy schematic, take ideas of sw and hw from others 2 projects that use that IC:
http://dspdap.sourceforge.net/hardware.html
http://www.mikrocontroller.net/articles/ARM_MP3/AAC_Player
Am I missing something? maybe I2C or SPI availability?
Nice to have Spark on team because he made DSPdap and worked with that IC ;-) :-)

oh no!! how could we miss the audio jack. we keep missing something or the other. audio is very crucial and should come bundled with the dev board.
