posted in Embedded |

You can use code injection and/or fake Radius server to gain root (SSH) access to La Fornera. But there is a much simple way : connecte your computer to the console port inside the Wifi router :

(sorry text in french on this picture, no time to translate)

I don't use any level adapter like max232 or max3232, just NPN transistors :

Pinout of console connector inside La Fonera is :

(too bigs capacitors here)
. . . . r
. w o . b
(SDRAM chip here)
  • r : red : Vcc 3.3 Volts
  • b : bleu : Ground
  • w : white : RX
  • o : orange : TX

First (ugly) circuit :

New circuit :

With connectors :

For USB connexion just use a USB/serial adapter. Next step : play with GPIO ! Yeah !

More information and other way to connect console :

    It’s okay. Even us stupid Americans know what the picture says. I say that because yes, we are stupid, and yes, some of us are painfully aware of it.

    It’s not a question of stupidity, smartness, knowledge or brain size. It’s a question of courtesy. French text on english blog = “sorry”.
