[Hardware Hacking General] AdamOutler:
Hey guys, I set up my Arduino Mega to communicate via UART with my Infuse4g.

The UART output comes out of the USB port at 115200kbps on the D+ and D- lines when you connect a 619kOhm resistor to USB Pins 4 and 5. It can be used for kernel debugging or general hacking around.

Here's some pics of my setup.

This emulates the "Test Board" from the KIT-S5PC110 which is used to develop the Aeries platform

You can make it do all kinds of crazy stuff....

Typical boot with battery just inserted.
