FOX-Board - The Board Running Linux By Chris Created 01/05/2009 - 14:08

Tutorials fox board linux programming The FOX Board is shipped with a ready to run image of Linux. In this quick guide we show the first steps to get started with it

Basic requirements This is a list of what you need to get start: a 5 volt DC regulated power supply like PS5V1A a PC with a web browser like Firefox or Internet Explorer, a Telnet client, a FTP client and/or a SSH client a LAN cross cable to link your PC to the FOX or a network hub or switch with two normal LAN cables

Power supply requirements The FOX Board requires a regulated +5 Volt DC power supply through the J14 connector using a commercial power supply like the PS5V1A (see the eShop section below) or through the J2 connector using a power supply for floppy disk driver. J2 is exactly the same connector used by the 3.5" floppy disk drives so it's possible to use a spare cable from a PC power supply unit or an OEM power supply like the Acme Systems FPS (see the eShop section below). Warning: do not use a cheap unregulated wall power supply equipment. It could damage the FOX board and all the USB peripherals connected into it. Only a well regulated +5Volt power supply must be used. The FOX Board alone needs typically a current of 280mA so a 5 Volt DC 500mA power supply should be more than sufficient for many cases. Otherwise if you connect one or two peripherals to the available USB ports you have to know the current that this peripherals need to choice the right power supply. Below is an example of the typical current needs for some USB devices:

USB peripherals powered through the USB host port USB/Serial RS232 converter: 30mA

USB Flash Disk (256MB): 50mA 4 ports USB Hub: 260mA USB Logitech Webcam: 280mA

USB peripherals powered with a specific power supply USB Iomega Hard disk drive 120 GB: 10mA USB Nikon CoolPix 5400 digital camera: 10mA

Power on FOX Board has no power switch on board so just plug your power supply and switch it on. All the three leds DL1, DL2 and DL3 will light on for a little while then only the green led will remain on. The meaning of this three leds is: Red led DL1 - It is a user defined led that could be controlled by your application software (it is mapped on PortA bit 3 of the Axis processor). Its normal state is off. At startup it is used by the Kernel to indicate an initial error state of the board. Typically it blinks when the MAC address of the ethernet adapter is not configured (this condition happens just after reprogramming of the flash memory with a boot_linux -F command so when also the kernel has been reprogrammed erasing all the bootblock information. Yellow led DL2 - It shows the LAN traffic on the Ethernet connector. Green led DL3 - It is connected directly to the power supply so it shows the power on state.

LAN connection The FOX board has a LAN RJ45 female connector for 10/100Mbit Ethernet network connection (J11). It's possible to link a PC directly through an Ethernet crossover cable (see How to wire an Ethernet crossover cable) or to a LAN switch or hub through normal (straight through) LAN cables. When you insert the LAN cable be sure that it's well plugged either on the J11 and on the LAN switch equipment. Check also that the link/act' led on the switch goes on. If you are using a 10/100M switch check also that the led 10/100M goes on. If these leds are off check that: the FOX Board is properly powered and the DL3 green led only is on the LAN switch is powered the LAN cable plugs are well inserted in their placeholders the LAN cable is not broken or defective The meaning of the two leds on the J11 connector is: Yellow led - It shows the LAN traffic on the Ethernet connector as like as DL2. Green led- It shows the power on as like as DL3.

LAN configuration The default network configuration of the FOX Board is: IP address: 192.168.0.90 Netmask: 255.255.255.0 Default gateway: 192.168.0.1

To see the FOX Board through TCP/IP from you PC you have to configure it on the same LAN address pool with a choice of IP addresses from 192.168.0.2 to 192.168.0.89 and from 192.168.0.91 to 192.168.0.254. Some valid IP addresses for your PC to be able to conect to the Fox board could be: 192.168.0.2 192.168.0.10 192.168.0.92 192.168.0.192 ...

When the LAN board on your PC is well configured, try to ping the Fox with (from a command prompt window): ping 192.168.0.90

You should be able to see the yellow led DL2 to blink and read on the PC the response time of the command. At this point you can access to the FOX Board Linux through: WEB access The FOX Board has by default a preinstalled BOA Web server. This article explains how to configure it and how to write your own web pages TELNET access The FOX board has a TELNET server always active and listening on port number 23. Let's see how to connect to it from our PC FTP access The FOX board has an always active FTP server that operate on the port number 21. Let's see how to connect to it from a Windows PC
