I’ve just started playing with a Fire COM on a Tobi board.  Hope someone can point me in the right direction to get serial ports working.

 

The 40 pin header on the Tobi board has a TXD1 and a RXD2 as well as a TXD3 and RXD3.  I’m assuming that these are serial ports.  But I can’t seem to get anything to come out on them.  I’ve tried minicom sending characters to ttyS0 through ttyS3.  Is there something I need to configure somewhere?  It appears that these are GPIO pins as well, so maybe I need to configure something.

 

Maybe someone can point me in the direction of the right howto.

 

Thanks
