Rockbox Player - Project to design and build a Free/Open hardware audio player
scharkalvin:
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 better
price could be had from the suppliers (well I can hope)?

I am working in external board, after finish, I will do that. Expressive parts in terms of price, are main board, which will be bought on Olimex. After the LCD + carrier board on SparkFun. I don't know If there will be the need to buy a JTAG cable in SparkFun... I bought one, It's my first time... Others parts are just resistors and capacitos, plus the audio codec which can be a sample from TI. I plan to make the external board on the company were I work, for me and maybe 10 more units, which I will try to assembly, with all components, and send by mail to developers.
I just would like to have a discount from Olimex, however, I will not do that! Because is a company from Bulgaria, which I think is a poor country then Portugal. I know a person from Bulgaria that told me that works about 10-12 hours a day... I think the price of the board from Olimex is a fair price. IMO, ipods and things like that are really cheap because of the low prices of hard labor work on China.
TIME: I think that we will stick with same hardware for at least 2 years. We can use the same dev board for develop thins like hard drive support, USB stack, or wireless, etc... - so, buying that dev board will be good to work on RB, I hope.
I were on IRC talking, here are some things about USB on Rockbox and wireless:
- I would like to know if RB work with USB? and If it works with some kind of wireless? - I am asking this because of planing hte hardware for RB player...
- Rockbox has no USB stack or no wireless.
- Rockbox works with USB under certain circumstances.
- The players it works on have some form of hardware USB-ATA bridge. Ones where we need a software USB stack, it doesn't work with yet
- So, It's a good idea to make an hardware with USB, or not? and the same question about wireless like bluetooth...
- adding any sort of wireless connection would require adding a ton of support to Rockbox
- okok, so, about connectivity, what a hardware player for Rockbox should have?
- usb
- what can you tell-me about the USB on the Atmel AT91SAM9260? - I would like to know If it have some kind of USB-ATA inside or not...
- it needs a usb stack
- at least, will the SD card work, on that board?
- sure, with a suitable driver it should
- so, the driver in RB for Sansa SD card will not work? - what are the difference? - hardware?... I am lost... :-)
- the (micro)sd thing in rockbox is for sansa, I don't know how suitable that is for your setup. should be mostly the same of course
- Unless you have the exact same hardware, attached in the exact same way, you'll always have to do some, possibly a lot, of new code.

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.

Yes it does. although still not properly functional on the Sansa/PP hardwares for which it only so far has been targeted at.

Nice to know that you would like also to jump on the wagon :-)
All hardware will be documented, we are just selecting ICs with full datasheets and most of them have application notes, examples :-)

So, after the chat, I will add USB to the list to develop software for. Would be nice to have developers with experiences to work on that.
About bootloader, Bagder told me that would be possible to use the 512MB NAND Flash to have a bootloader and also other part of the flash with a FAT32 file system. Bootloader will initialize hardware, mount FAT32 file system and init RB application thats reside on FAT32 file system - thats the idea I have :-)
