To pursue a cheap hardware, we should avoid that kind of things and get a custom, just as simple as we need. We should not generalize, we should focus e define what we want. I must say that a LCD+touchscreen looks very interesting, but that can be implemented later. If we work in mind to have hardware made by Olimex, there is no problem because they already have/are working on a dev board with that LCD+touchscreen.

See the prices directly and not on that site! Here:

--- Quote from: casainho ---So, what now? buy the boards and start coding?

you can buy the board if u inted to start porting right away. so far only 2 of us have approved for the processor. should we be getting more approvals especially from software experts here?
i still need to get TWiki permissions. will do so soon and update the hardware page.

Spark, we are just 3 interested. Me, you and scharkalvin. I think that software experts will say nothing in this message. We can ask direct questions to them at IRC.
I already talked with them about hardware:
Microcontroller: could be ARM7, but ARM9 should me the smart choice!;
RAM: for a flash player, 4 MB could be ok, 8 MB should be a smart choice specially If we will have album art - show jpeg, bmp files;
Flash memory: Have a connection for a flash card :-) and store Rockbox code and config files on 8 MB flash IC. 4 MB is +- the max size of actual Rockbox build.
The rest of hardware should be what we need/want. As we can see, that dev board surpass this minimum needs :-)
You have now TWiki permission, Mr. RogerQuadros :-)

Assuming the L9260 board, where does the audio go?

Audio goes trough I2C from MCU to TLV320AIC23 IC AUDIO STEREO CODEC and after to headphones :-) You can read more here:

Yes, I know that you've planned to use that TI chip, but how is that codec gonna be used on the dev board?

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 ;-) :-)
