Rockbox Player - Project to design and build a Free/Open hardware audio player
casainho:
Working status:
I received yesterday the development board from Olimex :-) - It's looks like to have a shortcircuit on 2 pins on the USB IC, I will take care of that next week.
With the dev. board came a CD with AT91 Bootstrap and with U-Boot - I did updated the RockboxPlayerPrototype page with that files and the bootloader section.
I had some e-mails with Roger aka spark, he are with short time to came to forum, however he gave me some ideas for the bootloader. He think is Ok this scheme for the bootloader.
He will soon buy the dev. board.
The next thing that we should focus is in have a Flash LED application that will be launched by u-boot. After that, the Flash LED application will be exchanged by the Rockbox Firmware application ;)

"AT76C113P" is the only chip I could find so the chip mentioned is up and coming, I think?
This is it http://www.hantro.com/index.php?349

friendlyzookeeper, why don't you want to focus and use what had already been done? - we already choosed the MCU, the stereo audio codec, the sizes of SDRAM and Flash, and even the dev. board.

All tools are for Linux and also for M$ Windows. GCC-ARM, text editor and USBprog, they are multi OS - you can see a good example here:

Thats for a at91sam7

Ok, but should work for the at91sam9. I bought that USBprog for make the JTAG using USB on PC, however I didn't test yet - maybe next week I will do that.

Ok,finally some update.Some good and some bad news.
My friend agreed basically because it won't cost anything for them.
That was the good one.The bad one is that in China factories don't work with small numbers,
the minimum quanity to build will be around 3000 units,since it involves creating a new case mold and new
pcb design.In total 3 factory will be required,one for the case,one for the pcb(by pcb i mean the pcb itself plus the component that require smt machine,excluding soldered components,like battery,jack,etc) and one for assembly.
I can see if we can lower the quantity,but will still be a big investment from our side.
So to decide if agree,we should have more concrete data.
How many people are willing to join the development?
If we have developer known to have experience in this field,we could send the development board to them to speed up the process.
Speaking of the development time,6 months seem a bit much for this project,not because it's long per se but because it's open source,and if it catches enough interest any company could just take the design and make it before us.So the shorter the better.
Last thing,as i said before,since it require a big investment it should be more commercial possible.
So I would like to evaluate any proposal you guys will make that won't collide with the original purpose.
Example,we ditched,touchscreen,and touch button and it's fine but if anyone have suggestions for the control is highly welcome.For example a click wheel,similar to the new iriver models could be an example and it won't hurt the design.Any cool feature is accepted,because on our side won't change much 5-10 usd more but could greatly improve sales.The key is to make it unique by merging features not present in current players.

what's wrong with ordinary buttons? Last week I tried a friends ipod - it was horrible. In my opinion a clickwheel is a very ineffective tool for browsing long lists and an ergonomical nightmare.
00christian00:
That's not the wheel i meant,the ipod one is a touch wheel.
I meant like this :
Or like the Sony Ericsson P900 Jog wheel.It's really handy,and not meant to replace buttons.

I see.. what are they needed for?
