Welcome to my blog

My name is Sven Andersson and I
work as a consultant in embedded
system design, implemented in ASIC
and FPGA.
In my spare time I write this blog
and I hope it will inspire others to
learn more about this fantastic field.
I live in Stockholm Sweden and have

Zynq design from scratch. Part 26.
Running a DHCP server

As we have seen earlier, PetaLinux expects to get its IP address from a DHCP server running in the network. We have setup a private network in this experiment and have no connection with the router that normally runs a DCHP server and generates IP address to all our computers. For that reason we need to setup and run a DHCP server on our host computer. I don't know about Windows PC, but MAC OS X has included a DHCP server that can easily be setup and started. Here is a good description.

Windows DHCP server

Open DHCP Server is an alternative for all Windows users.

Mac OS X DHCP server

The server is called bootpd and does both DHCP and BOOTP. These instructions just describe using it for DHCP, however. To start, you need to create a configuration file for the server. The file should be stored in /etc/bootpd.plist. Here's a sample configuration file:


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">
<dict>
<key>bootp_enabled</key>
<false/>
<key>detect_other_dhcp_server</key>
<integer>1</integer>
<key>dhcp_enabled</key>
<array>
<string>en0</string>
</array>
<key>reply_threshold_seconds</key>
<integer>0</integer>
<key>Subnets</key>
<array>
<dict>
<key>allocate</key>
<true/>
<key>lease_max</key>
<integer>86400</integer>
<key>lease_min</key>
<integer>86400</integer>
<key>name</key>
<string>192.168.33</string>
<key>net_address</key>
<string>192.168.33.0</string>
<key>net_mask</key>
<string>255.255.255.0</string>
<key>net_range</key>
<array>
<string>192.168.33.2</string>
<string>192.168.33.254</string>
</array>
</dict>
</array>
</dict>
</plist>

This file sets up the DHCP server to run on the interface named en0, which is typically the (non-wireless) Ethernet port. It assumes that that port has been configured with the IP address 192.168.33.1, and dishes out addresses from 192.168.33.2 to 192.168.33.254

To start the server, run the following command:

sudo /bin/launchctl load -w /System/Library/LaunchDaemons/bootps.plist

Stopping the server is very similar:

sudo /bin/launchctl unload -w /System/Library/LaunchDaemons/bootps.plist

Booting PetaLinux

Next time we boot PetaLinux we will see the IP address 192.168.33.2 leased.





Here is the result from the ifconfig command:





Communicate with the ZedBoard

We can ping and telnet to the ZedBoard.

Hi Sven,
Thx a lot for your blog, it help me a lot.

I developed an application that allows me to update data on the webserver of petalinux.

In the end I would like to get with any computer, connect me on the map and get to the webserver without further manipulation than return the IP address of the card

Do I need to install a DHCP server on the Board? I would not have to configure my IPV4 address every time I want to connect to the Board.

Do you know how I can do this?

Cheers
