Getting started with iMX6 Rex Development kit

These steps will help you to power up your iMX6 Rex development kit for the very first time.

1.Plug the module into the baseboard

The important parts to build the kit

Notice the position of the thumbs

2.Add spacers and tight up all the four screws

Notice how the spacer is moved between the module and baseboard

Plug a screw into the mounting hole and secure it with a nut.

Use a screwdriver to tight it up.

3.Place the Heatsink

Remove the red protection foil from the heatsink.

Place the heatsink on the top of the processor.

4. Connect Serial Cable

Connect the iMX6 Rex RS232 serial port to your computer.

Use the cable from development kit (it has to be a null modem cable with crossed wires). Run

Hyperterminal (or download and use Tera Term

at: http://logmett.com/index.php?/download/tera-term-

482-freeware.html

).

Set the following serial port parameters:

Baud rate: 115200

Data: 8

Parity: none

Stop bit: 1

Flow control: none.

5. Connect Network Cable

Use the network cable delivered with your development kit (this cable is rated for 1GB Ethernet).

Connect the cable between your iMX6 Rex development kit and a network switch (possibly a computer).

Connecting the baseboard to a network is not required, but missing network may slow down booting process as Linux will be waiting for a DHCP answer.

6. Connect HDMI Cable

(Optional)

7. Insert SD Card

Insert the SD card delivered with your development kit into the slot placed on the edge of the board. Be sure the other SD card slot is empty.

8.Connect the power

You have two options, how the board may be powered. Be sure, your power supply can deliver enough power!

Option 1:

Use a 7V to 24V DC adapter (usually 12V/2A is fine) with a power jack. The plug diameters are 2.1mm x

5.5mm with the positive voltage in the middle.

Option 2:

Use an ATX power supply.

9. Update network configuration

After you connect the power, the board will start. Watch the console messages in your PC terminal. Once you see how the u-Boot autostart is counting down, press any key (e.g. ENTER) to interrup it. Updated the u-boot parameters based on your company network setting. Here is an example:

> setenv gateway '192.168.1.1'

> setenv netmask '255.255.255.0'

> setenv ipaddr '192.168.1.78'

Select a valid IP address from your network to use an initial ping and insert this command:

> setenv bootcmd 'ping 192.168.1.1; run bootcmd_mmc'

In the case your server does not support DHCP, set a fixed IP address and network mask which will be assigned to the Rex board after it boots up into the Linux:

> setenv bootargs_mmc 'setenv bootargs ${bootargs} ip=192.168.1.78:::255.255.255.0 root=/dev/mmcblk0p1 rootwait'

Save the u-boot parameters and restart the board:

> saveenv; reset

Now, your board should boot up into Linux. In case you have any problems to setup your Development kit, check out our FORUM & Questions at: http://www.imx6rex.com/questions/ or contact us at: www.voipac.com

Enjoy!

NOTE

Start the X-session on HDMI after booting Ubuntu 13.04 from the console by commands:

# export DISPLAY=:0.0

# startx &

IMPORTANT!

These commands may not work on every filesystem - tested with Ubuntu 13.04
