Why do you think that? I would expect CE-ATA to be the new standard for 1.8" drives. It's used in the 160GB version of the ipod classic.

I did create a new message just for discuss ideas, suggestions, for the RockboxPlayerV1 - http://forums.rockbox.org/index.php?topic=15173.0 , please use that message and not flood this message thats pretend to be just for the RockboxPlayerPrototype or general project:

casainho, you did a good job by separating proto and v1
HDD/CF interface
whether we go for 2.5" HDD due to lower cost or 1.8" HDD due to smaller size, we need an IDE interface.
the 9260 cpu has a CF controller which can be easily adapted for a HDD.
http://www.atmel.com/dyn/resources/prod_documents/doc6023.pdf
using SATA drives will only complicate the matter without any significant gains.
CF or SD flash
now since an IDE interface is allowing us to use CF and HDD, should we still stick to SD card for v1?
casainho:
Spark, can you please answer to my question "As you suggest, after finding a vendor for PCBs, who will buy components, assembly it in quantities and sell it online?" - Do you have a better option?
And lets that discussion of a kind of HDD for the message for RockboxPlayerV1 - http://forums.rockbox.org/index.php?topic=15173.0 . For this RockboxPlayerPrototype, we just have SD card on hardware.

sorry casainho, i missed to reply to your question. i don't have any option yet, but definately there will be many guys interested once we have Rockbox runnin on RockboxPlayerProto. And there is quite some time for that.
If we have the schematics done for V1, don't you think vendor's like olimex will be interested?
more than the PCB and assembly i'm worried about the enclosure. u know anyone who can make and sell an enclosure at a cheap rate?

Yes, and we must take advantage on that interest ;) :)

For sure, however, I believe that we can accelerate the process and help them If we use hardware that they already use on their dev boards, because they have experience on that hardware, since from design(have libraries for schematic and PCB), to find/buy the components till assembly it.
If we design the schematic for V1, Olimex will probably need to redesign it again internally, for a few reasons. However, I changed a bit my ideas now :-) - we don't loose nothing in have it designed by ourselfs, specially If we have resources to do that, If you like and want to do that, go ahead :-)
But, remember that we must find help at assembly and sell online the project!!! - I don't have resources to do that nor I want to do that! I assume that you to... so I guess the best option is have Olimex or others to do that, so, we must work with them, using the hardware that they use on theirs dev. boards(Olimex example).

Now, I don't. We have the option of the - http://www.emachineshop.com/ - Online Machine Shop - Download the software for free, design the case in 3d, and it tell you the price you will pay. This is ideal for a prototype or small quantities.
Maybe we can define a design, sizes of the V1, make an expensive prototype of the enclosure and then try to contact any company as we are doing for hardware. Good was having it selling on online shop with plastic case already! It can be possible, I think.
I am reading now the:: Application note from Atmel: Getting Started with the AT91SAM9260 Microcontroller.
external PCB
Can someone(with more experience than me, which is almost none) draw the external PCB in KiCad? - I want to start drill that. Sharkalvin suggested to seperate analog vdd and gnd from the digital vdd and ground. (the AEXT connector has analog vdd and analog gnd). This will reduce noise in the nanalog signals..

MattAndrew added himself to the project page. He haves wrote this on his page:
As a student project this semester (spring 2008), I'm designing and building a portable mp3/ogg/flac/etc player that will run rockbox (yes, I'll port rockbox to it). The designs for the circuit board will be licensed under the creative-commons (by-nc-sa).
The music player will be based on an atmel arm9 and have a organic led display (124x128, 18 bit color). For storage, there will be 2 sd/sdhc card slots. It will have the usual lithium ion variant battery and charge via usb. The software will be stored in serial flash and be copied to ram upon bootup.
I'm not trying to compete with any brand's commercial player, I'm just not satisfied with what's out there (basically I want a quality sd-card based player with a color screen that plays oggs and mp3s). The end result of this project should be a circuit board that can be printed by a board house and then soldered by the advanced amateur, although only a few might ever get made.
My student project last semester was a clock based on an arm7 with the same organic led display I'm using for this music player. The software is all written in assembly language and is open-source. The designs for the hardware are licensed under the creative commons.
I searched and I find his blog, with pictures of his works :-) - http://ohmslog.wordpress.com/
EDIT on 30.01.2008:
We have another Prototype page - RockboxPlayerPrototypeB :-) :-) - let's discuss ideas and see what is the best... I am really loose but happy :-)
