Serial console is not working with Colibri iMX6DL on Iris carrier board

I’m using the Iris carrier board and Colibri iMX6DualLite module. After the board is powered on, I get garbage data in the minicom console.

Command used to launch the minicom: minicom -D /dev/ttyUSB0 -b 115200

dmesg output when connecting the Serial2USB module:

[674670.591840] usb 1-2: new full-speed USB device number 9 using xhci_hcd
