Welcome to the Rockbox Technical Forums!
Is this going to be a pda right now or you want to just get mp3 to play?I'm familiar with Atmel and loading linux on a pda (bootstrap).
Casainho,add some smilie once a while otherwise it seem you are scolding him I doubt you were doing it,since you are asking for help,but it's really easy to be misunderstood while writing.
I pointed it out because i noticed many misunderstand you,so if you put some smiley it's more clear.That website doesn't explain what "to scold" mean.To scold mean telling someone that is action is wrong,like what a teacher would do with some children when they don't do homework for example.Sorry it's hard to explain in english.
If you look at current devices that do more than just audio (e.g. simple games and 2-3 different video formats) you'll notice that they have far far better battery runtimes than daps purely designed for audio.Take the Cowon D2 as example (rockbox port being worked on). It supports various video codecs, has a nice and large LCD (320x240) and "Rated battery life: 52 hours for music, 10 hours for video" (linky). :-D
If this player should compete to other commercial player I wouldn't go below a resolutions of 220x176 (larger LCD means more space for a larger battery ;-)) and a SoC being able to handle MPEG4 with 30fps easily.
Mpeg4 support is not present in rockbox.I don't know if someone could port ffmpeg or some other similar fast decoder.
Simple because they were design for video and not audio! So they have a large and expensive battery. We want also a player that is small and cheap, and we get It reducing audio for 24 hours, for example - so we can have a battery less than half of that one, and cheaper. The money saved on that, can be put on good quality hardware for recording and playing.
As soon as this devices get SoCs for video, they will also have large memories and batteries that can handle Linux.

But as we can see, portable players are quick getting media players, who will invest in good, only, portable audio players?
You do the same mistake as lots of others when you think Rockbox is simply a better option as long as everything is small and tiny. Rockbox is not only an OS but also an application suite and everything in Rockbox has been crafted for portable media players, for usability with few buttons and for long run-times on batteries. I'd like to see you config your "Linux with VLC" to be even near what Rockbox is.
Can you name any audio player manufactured and sold the last 2-3 years that cannot also display video?
Why should we tailor the hardware for video? just because everyone is doing that? why should we go to touchscreen? just because everyone is dong that?
