Got a new Toy. It’s a Juicebox from Mattel, a kids video and mp3 player. Actually it’s a linux based and has Samsung S3C44B0 ARM CPU, 8MB Flash and 2MB Ram. Since it has JTAG Pinouts you can use it as a really cheap ARM Dev Board. You can’t get one for around $10 at ebay. You find a lot of good info [here](http://www.elinux.org/wiki/JuiceBox).
Made some LCD test stuff, a 3d starfield and a simple fire demo. This code runs directly on the hardware not on top of the build-in linux. You need a JTAG cable to download the code directly into the RAM.
I’m using [openocd](http://openfacts.berlios.de/index-en.phtml?title=Open+On-Chip+Debugger) for this:
halt wait_halt poll load_binary lcd_3.bin 0x0c001000 resume 0x0c001000
