@john-frailey said in Change Serial Console on Boot to ttyS1:

I've got an environment setup on a io board , that I would like to switch the linux console port from ttyS0 to ttyS1. I wasn't sure if that is done in /etc/inittab or in one of the system config files ?

I have an omega2.

I'm not sure how Oninon's kernel does it, but in Mediatek's, Linux detects which UART U-Boot activated and uses that.

You could override this in the kernel if building it from source - I had to as I turned on a second one in a custom U-Boot, and Linux was then not using the one I wanted.
