=== Debug Port ===
There is a serial port for debugging. This port can be accessed via one of the two TIB RJ45 jacks, but only after
a small hardware modification has been made. Please reference the following picture for details.
After soldering those two connections, the pin-out of ''TIB out'' is as follows:
* Pin 7: PPC UART Tx (3.3V)
* Pin 8: PPC UART Rx (3.3V)
* Pin 10: Ground
You can use any level shifter to get the signal up to true RS323 values, or directly connect something like a FT232.
The port runs at 115200 bps, 8N1
There seems to be some kind of serial console on the device, we haven't yet figured out more details.
