I use the Sabreauto board.

I'm trying to change the yocto debug port.

Sabre board confirmed it was uart4.

I'd like to change it to uart3.

I saw an article written by victor Wang .....https://community.nxp.com/thread/319950 <-- good

 

question!!

Why do I need this part to change the debug port?

<yocto>/source/meta-fsl-arm/conf/machine/include/imx6sabresd-common.inc

      SERIAL_CONSOLE = "115200 ttymxc2"

 

Does it not work if I change it only on uboot and kernel?

 

best regards.
