Hi!
I am from Russia
Long enjoyed this player on my phone Motorola E6
Ready to help in the development of the project
In programming I'm not very strong
Can help with electronics
I have a few questions and suggestions
I do not understand why the chosen ARM 2440?
He is an old USB1.1
Maybe only because of the price?
You used Mini2440 ARM9 Board
I found a micro-2440 Board

Get on it to run your firmware?
I want to buy this designer
I want to use the CPU module separately to reduce the size of the player

I propose to use
I am in their designs using LiPol batteries and charge them LTC4054

To monitor the battery in collaborative projects using DS2745

All I can say is that this is an incredible project that I'm going to continue to follow, and I know I've come across it at a pretty exciting time in its development cycle, when all the major features (most of all sound playback) are now functional, firmware is running without issues, touch screen functionality is implemented, etc. Overall, this progress is wonderful. Find a manufacturer to mass-produce these, and I would happily purchase one myself from Amazon or wherever you'll eventually make it available. I would recommend the color black (especially if you can't manage to slim it down; let's not lose any of those customers that buy based on appearances) and 16GB and 32GB models. This mp3 player, I believe, represents another milestone for the free software movement.
And perhaps you could implement something approximating software crystalization/expand or SRS WOW in a future version of the hardware. ;)

Another question
USB stack is implemented?
How to throw music on SD?

anten44733,
I'm pretty sure the design of the hardware is about 100% finished, including USB. Sound was actually one of the last things that ended up becoming functional, but now it works too. I wish they'd use a smaller battery and do anything else that would result in a thinner final product. The current prototype appears to have the dimensions of a shoebox. :)
To put music on an SD card, you either sync to it with your favorite music program or simply copy and paste the files to the drive. I actually like the idea of customizing the mp3 player's memory for a change, although 32gb SD cards are still too expensive at this point.
