Thank You for your continued support and contributions!
Also, don't be fooled by the fact that they (can) run Linux. These guys don't release the source for their drivers and the manufacturers of the hardwares don't release their docs to us, so a Linux running on them is very little help to actually get Rockbox ported to them...
...Rockbox as a stand alone firmware will always have the potential to get better battery life and performance than MPlayer on Linux on the same hardware. So, if you're actually buying a portable player for portability and on-battery use, Rockbox will always be an alternative if you actually want efficiency.
QuoteYou said AVR32, but they also have an ARM right? - for what I understand, RockBox have good support for ARMs... what would be the good choice? ARM or AVR32? - Atmel have ARM and AVR32 dev board...Well it looked like the avr32 had everything but the kitchen sink in it, including the required AC97 D/A, LCD hardware interface, flash memory interface, USB interface, and even ethernet! Their arm offerings would require external hw to do much of this. The downside is having to work with BGA packages, but that's what the world is going to.

can you help to do some analysis between "AT91RM3400 Development Kit User Guide"(ARM) and "AT32NGW100
The person(s) who'd do the port would most likely need a board as well, and if you tailer the port to the specific board you will need to make your final design pretty much identical to the dev board.
Does the dev board even come with buttons, LCD and nand/disk ?
LCD interface on NGW100. Here's how:http://dma.elektroda.net/projects/ngw100_ext_lcd/ngw100_ext_lcd.htmlThe LCD for this guy is about $50. If someone can copy the pcb and get some made(need to add header breakouts for some kind of keyboard and AF amp to the D/A on the main board) this would be a good way to start. Probably talking about $200-$250 out of pocket for the dev board and the i/o board + LCD. Maybe someone could get a deal on the LCDs if enough people signed up to buy one.Atmel sells a jtag interface for $300 and avrstudio for the avr32 RUNS ON LINUX! (also windoze)
The jtag would...
The color LCD is probably the way to go, it's what's expected in players of this type.
atevk1100
Quoteatevk1100That's not the same cpu. I'm not sure it has the flash disk interface nor the A/D hardware. Atmel makes two families of avr32 cpus. The one you quoted is the smaller, less powerful one. (won't run Linux). We REALLY want to use the AP7000 family!
