UART question

Hello,

When you boot the beagle board you can see the progress on the Teraterm through the UART port. I was just wondering what determines which UART port to communicate with the Teraterm please?

Thanks,

John

In Ubuntu you have to edit the file /boot/uboot/uEnv.txt and change the line:
optargs=console=tty0
To:
optargs=console=ttyO2

If you want all the init messages go thought the UART.

If you want all the messages kernel and init through the screen console, leave unchanged the previous line and change the line:
console=ttyO2,115200n8
To:
console=tty0,115200n8

Then restart.
