Refer to carrier board user manual for the Linux console cable connection. Then launch and set the terminal as follow:
Minicom
It's a simple terminal program, easy to configure and use. Can be downloaded and installed from your Linux package distribution (Synaptic, apt-get, yum)
Minicom is a terminal emulation that can access a remote serial console enabling the configuration of Bootloader or the flash file system of the board.

minicom -s
In the menu, choose Serial Port Setup
Below, the configuration option:
+-----------------------------------------------------------------------+
| A - Serial Device : /dev/ttyUSB0 |
| B - Lockfile Location : /var/lock |
| C - Callin Program : |
| D - Callout Program : |
| E - Bps/Par/Bits : 115200 8N1 |

Setting up the u-boot device tree variables for Engicam boards.
Power on the board and stop on the u-boot command line prompt.
To stop the automatic booting of the pre-installed kernel, you must send a character to the serial port by pressing a key from the serial console connected to the target (See the hardware manual for serial port connection).
Once the u-Boot is stopped, you can send the commands to set the right device tree for your board.
I.E. :
Suppose to have an openframe 7 inches with the microdev board connected.
The commands to send for devicetree configuration are:
setenv fdt_file microgea-mx6ull-microdev-yes7.dtb
saveenv
Below a table with all the devicetree used:
