> Hello there, I'm Aditya from India. I've ordered a Olimex 9260 board for developing the rockbox player, I'm a novice with arm. Can u help me get a kick start with this. I'm really sorry for this abrupt mail, but I've taken this player as my project in college and really want to help the community develop this hardware. I even plan to make the jtag myself for this, can u suggest a few books or links where I can start on this board/platform. Anything relative, I've read about this processor, its architecture but I'm just a guy who works on robots with 8-bit processors and assembly.....
> Any kind of help will be of great help. Hoping for a reply.

Whats happened:
1. Well we have gained another developer from india making us a threesome
2. We are a little bit stuck at the moment getting the rockbox bootloader to work on the dev board if there are any AT91 developers out there that might be able to help we would appreciate some guidance.
3. Just been updating the http://code.google.com/p/rockboxplayer/ pages to help any new comers to understand what been going on and how to join in.
Tom

EDIT on 2008.10.22:
A new developer joined the team:
AlexCantos - also AJCantos. Joined as a developer in October 2008. EXPERIENCE: I work in a small audio electronics company. My skills include hardware, embedded software and some mechanical design. I CAN HELP IN: I can develop/test/improve hardware, implement software and do some visual/conceptual design. MOTIVATION: I love audio electronics, gadgets, open source and Rockbox, need any more reasons?
--- Quote from: friendlyzookeeper on October 12, 2008, 11:08:46 PM ---I might explore some of the advantages of AVR32 over the atmel arm9 board. The ngw100 board makes a sound choice for now. I can mark up an AVR32 64-TQFP (at32uc3b chip) with an adapter into a project. It just has full speed usb and 60 MHz max. frequency. For now, it looks to be my better choice, sorry guys. The ngw100 board is $73 usd from mouser and many specs that I'm looking for in a learning project and still uses the same tool chain. Very useful, hope you agree.

I do not agree :-) eheh - At first I wanted to use that MCU and that board, until RB developers explained that RB source is prepared for ARM, because of assembly optimizations and so on.
I really like the idea of AVR32, I am being working with AVR USB and also I am looking with other persons to do a kind of dirty cheap DIY AVR32 board :-)
And yes, Arduino is great, GCC is great, all this Free Software tools and Atmel MCUs are great ;-) -- go to have a look at AVRopendous and MyUSB Lib.

I think that any developer with knowledge on ARM assembly and C start up code would easily be able to help as at this moment (not need to be on AT91 MCUs)...
Bagder:
I'd like to repeat here what I've repeated in the IRC channel for the last times this target has been discussed:
If you guys would simply produce good patches against current Rockbox SVN and post them, like in the patch tracker, you'd get much more people who'd read your work and who'd easily could try out building the stuff for your target. And possibly help out fixing flaws in your build setup, lds scripts, makefiles, crt0.S files or whatever.
You need to bring your code to the Rockbox way of life, rather than sit in your own corner of the internet trying to lure over Rockbox hackers.
You'd also be sure to work faster and more in a straight line towards integration in the main Rockbox source code, which I assume is something you want.

Unfortunately I don't know how to do patches nor how to post them - but I think Tom may know that so I would ask him to do it.
Now we are stuck on a problem that first occurrence of interrupts hangs the system - I believe the problem is within linker script, C startup code or even the version of GCC used to build Rockbox that is different of that used to build our Flash_LED code.
Was we are looking for guidance, I appreciate your help on saying this again Bagder, we will do it for sure. Thank you :)
