Debug serial port on SABRE outputs rubbish

[emil]

I've just copied the images to the eMMC with the MFGTool using this option in the cfg.ini-file:

board=SabreSD

name=i.MX6DL-SABRESD-eMMC

Description:Download the u-boot, kernel and Linux rootfs to the eMMC

I have a usb cable conected to the USB to UART port and I can see things happening on the terminal. All of a sudden when booting up linux i start getting rubbish on the serial port. It seems like the bootup routine is doing something with the serial port. Also, I would like to know how to configure the boot environment variables so that I can get the video output on the touchscreen (which comes with the SABRE Smart Devices kit).

I'll attach the log from the serial output.

Thanks.
