Welcome to the Rockbox Technical Forums!
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.
.Leave some room space to solder any new connector to not used pins and bus or.Leave some expantion socket that you can latter add something else..USB host capabilities will be a step ahead, for my webcam Ideas : ).Seams AVR have CCD sensor interface capabilties make it open too : ).LCD seams nice for this aplication, but 128x128 wont be for other, make planed somehow to expand this..Think that will be nice to plug power in board, to dont need use the battery charger.I sugest casainho to put in wiki page some table with this ideias and other as possible specifications and wants for this. Put a rate in each one like: "Essencial, Important, Desirable"EDIT: 23 Jan 2008The nordic RF chip sugested by Olimex seams to be really a nice chip, I've alreade study datasheet because I'll use it in my work. But, actually it gives you only 2Mbit/s that shoulndt be too much if share large musics
About wireless connectivity, I will work on the idea after the 1st version of the player. I would desire something to connect with portable devices for sharing files, the player will not browse the internet to download files but It should connect to others devices that can do that, IMO.

Will somebody put together a complete BOM with cost of parts and links to where to purchase?If enough people are interested maybe a group buy package might be available and a betterprice could be had from the suppliers (well I can hope)?
- Rockbox has no USB stack
When you guys decide to buy something, I'll chip in for one or two. I know next to nothing about hardware, so it could be a good learning opportunity if you guys let me bug you every time I break something.
Quote from: casainho on January 24, 2008, 06:19:06 PM- Rockbox has no USB stackYes it does. although still not properly functional on the Sansa/PP hardwares for which it only so far has been targeted at.
I said it can boot from NAND since the data sheet for the MCU says it can. Separating the flash in several partitions, like one for the boot-loader and another for a FAT filesystem should be trivial.However, which I've tried to get through on IRC, since the planned player hw has no NAND flash of its own (other than replaceable memory cards) I think it is a bit of a waste to write a special boot procedure for the dev board only. I would then probably instead focusing on booting the devboard from USB to make it easier to develop with faster round-trips.I am however not at all sure about which of these hardwares you refer to when you speak about lots of stuff in this project, and I'm certainly not sure which or if both of these that have the serial NOR flash.Also, I'd suggest you go for building and using u-boot as bootloader as I'm quite sure that's already ported and working fine on the AT91 SAM9 targets. That will also allow you to load Rockbox over ethernet (TFTP) while developing and that'll be very convenient.
