Quick Start Guide of EVK-MXM-8310

These quick start guides are intended to provide developers with simple instructions on how to install MXM-8310 evaluation kit from very beginning and have it monitoring your local device in few minutes. No advanced installation options are discussed here - just the basics that will work for 95% of users who want to get started. This guide will lead you through the process of configuring, installing, and developing MXM-8310. This guide was written to be as clear as possible and to provide only the details necessary to get you up and running. For more in-depth information, links to other chapters will be located where appropriate.
Step 1. Plug MXM-8310 into the carrier board and tighten it
Figure 1 Plug MXM-8310 into the carrier board and tighten it


Plug MXM-8310 in the carrier board of the evaluation kit at 45 degrees and press down. Use a cross-head screw driver to tighten it. The recommended screws specification is M3 (Metric 3mm head), F-head (Flat head), 5mm in head diameter and 4mm long.
After done, plug the CF card with pre-loaded file system into CN25 (CF socket) connector. The CF card with pre-loaded file system is part of the evaluation kit.
Figure 2 Plug the rootfs pre-installed CF card into evaluation kit



Step 2. Check Jumpers and Switches
Different configurations can be set by several jumper blocks on board. For example, if you attached an LCD, JP4 needs to be shunt depending on your LCD is 5V or 3.3V.
Step 3. Connect the Console Serial Debug Cable from evaluation board to your PC
Connect the DB9 to RJ-45 console debug cable from CN6 of the evaluation board to the COM port your PC. Open the Hyperterminal program of your PC and set the baud rate as 115200, 8N1.
Figure 3: Connect Console Debug Cable



Step 4. Apply 5V to the device
Apply 5V to the mini-ATX connector of the device as shown in figure 4.
Figure 4 Apply Power to Evaluation Kit



You will see the boot messages from the Hyperterminal as shown in figure 5.

The default root password is "xpc8110" (no quot). You can use passwd command to change the root password.
Step 5. Network Configuratio
Plug an Ethernet cable to CN12 of your device first.
The default IP address is set static and network configuration is as follows.
IP address 192.168.1.122
netmask 255.255.255.0
gateway 192.168.1.254
[root@xpc8110 ~]# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 10:0D:FF:FF:00:0D
          inet addr:192.168.1.122  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1546 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:153475 (149.8 Kb)  TX bytes:0 (0.0 b)
          Interrupt:73 Base address:0x2300

[root@xpc8110 ~]#
Users can use ifconfig to change the IP address at runtime.

Example:
Below is an example to change the IP address to 192.168.1.123 and netmask to 255.255.255.0 at runtime.
[root@xpc8110 ~]# ifconfig eth0 192.168.1.123 netmask 255.255.255.0 up
[root@xpc8110 ~]#
Change Network Configurations Permanently:
The ifconfig command only changes the network setting at runtime. After reboot or network restart, the network configuration will be restored to default values. To configure the network configurations at boot or network restart, users need to modify the /etc/sysconfig/network-scripts/ifcfg-eth0 file. Network configuration will take effect at next boot or network restart.
Step 6. LCD Connectivity
If you need to connect an LCD, use a FPC cable or LVDS cable (depending on the type of LCD) connect to the evaluation board of MXM-8310 first. Check if JP4 is configured properly. The FPC cable at the board side (CN22) is top-contacted. You will need to power the backlight yourself. XPC-8310 provides users with a 12V bypass path from pin 2 of CN3 to pin 1 of CN2 for the backlight connection.
Figure 6 shows the LCD connection.

The device descriptor of the LCD is /dev/fb0. For Embedian default root file systems, there will be no outputs to LCD.
To better protect your LCD, the panel power (JP4) and backlight power (pin1 of CN2) is controlled by two switches via two GPIOs and default is set to off. You will need to turn it on first by the following command.
[root@xpc8110 ~]# modprobe backlight
LCD backlight & panel power control interface for XPC-81xx.
This is to load driver that control the switches.
[root@xpc8110 ~]# echo "1" >> /proc/panel_power
GPIO-88 autorequested
[root@xpc8110 ~]# echo "1" >> /proc/backlight
GPIO-97 autorequested
[root@xpc8110 ~]#
This is to turn the switches on.
The LCD driver is a kernel module and you need to load the lcd module first by the following command.
[root@xpc8110 ~]# modprobe pxafb
Users also need to use fbset command to set up the frame buffer first. The settings are located in the file /etc/fb.modes. After done the above steps, users can cat a simple pattern to LCD to see if your LCD is wired correctly.
