10 | 1 | laforge | |
11 | There is a serial port for debugging. This port can be accessed via one of the two TIB RJ45 jacks, but only after |
||
12 | a small hardware modification has been made. Please reference the following picture for details. |
||
13 | |||
14 | After soldering those two connections, the pin-out of ''TIB out'' is as follows: |
||
15 | |||
16 | * Pin 7: PPC UART Tx (3.3V) |
||
17 | 3 | laforge | * Pin 8: PPC UART Rx (3.3V) |
18 | 1 | laforge | * Pin 10: Ground |
19 | |||
20 | You can use any level shifter to get the signal up to true RS323 values, or directly connect something like a FT232. |
||
21 | |||
22 | 2 | laforge | The port runs at 115200 bps, 8N1 |
23 | |||
24 | 1 | laforge | There seems to be some kind of serial console on the device, we haven't yet figured out more details. |
