Rockbox Player - Project to design and build a Free/Open hardware audio player
casainho:
Well, AVR32 or not? :) - I vote for It, because in future there will be versions with USB OTG, more rapid, low power, etc... and we will have full datasheet and GCC-AVR32 :)
My question is, can someone help to port RB for AVR32?, in this case, using a $100 dev board, with all hardware documented and a GCC port for AVR32? - I can buy the board to test but I am not able to port RB :( - I hope to learn in the process...
In the next days I will dig the at32ngw100 dev board, try to know what can be done and what hardware is needed do add for have a simple player. One thing is a display.
About PCBs and assembly ICs, I would let that for future thinking, in some way that must be done. Who knows If I can have some made in the company where I work - We have material and machines, but we don't have the project nor we have knowledge to do that.
Bagder:
The person(s) who'd do the port would most likely need a board as well, and if you tailer the port to the specific board you will need to make your final design pretty much identical to the dev board.
Does the dev board even come with buttons, LCD and nand/disk ?

Bagder, developers at RB can buy their own hardware or they rely on others offers?
If at32ngw100 dev board is low cost, made by professionals, I would copy/use the circuits of dev board.

I will dig the board info to know what needs to be add for a for have a simple player. I would appreciate help here :)
Board comes with 32 MB SDRAM, 16 MB Flash (8 MB serial and 8 MB parallel), SD card and USB. It misses LCD, buttons (should be very ease to add), DAC?? I don't know about it.
Here is an image of the board:

LCD interface on NGW100. Here's how:
http://dma.elektroda.net/projects/ngw100_ext_lcd/ngw100_ext_lcd.html
The LCD for this guy is about $50. If someone can copy the pcb and get some made
(need to add header breakouts for some kind of keyboard and AF amp to the D/A on the main board) this would be a good way to start. Probably talking about $200-$250 out of pocket for the dev board and the i/o board + LCD. Maybe someone could get a deal on the LCDs if enough people signed up to buy one.
Atmel sells a jtag interface for $300 and avrstudio for the avr32 RUNS ON LINUX! (also windoze)

I was not expecting the $300 jtag for developing :( - Is there a cheap way to develop and debug?
I am lucky because I use in my work a JTAGICE mkII for programming and debugging AVR8 which looks like works also for AVR32.
That LCD is very expensive! does we need a display like that? - I would be happy with one black and white, AND with serial interface, which we will win simplicity wiring, so less trouble, less difficult.
