Required packages for cross platform development:

sudo apt-get install autoconf automake libtool libexpat1-dev libncurses5-dev bison flex patch curl cvs texinfo build-essential subversion gawk gperf git libncurses-dev gcj-jdk

We will need to run an NFS server to host a NFS root file system for CoBo.

sudo apt-get install nfs-kernel-server

# edit exports /etc/exports and append

/home/attpc/dev/coborootfs 192.168.40.40(rw,insecure,no_root_squash,sync,fsid=0)
/mnt/local/export/filesystem 192.168.40.45(rw,insecure,no_root_squash)

The second line in exports is just for ML507 Reduced CoBo compatibility.

Finally, run the following launch the nfs server:

sudo service nfs-kernel-server start

The DHCP server is required to allow different CoBo boards lease an IP. Currently, we are using static IPs based on the MAC address of each CoBo. This is a good practice for development, however, in deployment it might be just easier to assign random IPs, depending on the setup required.

sudo apt-get install isc-dhcp-server

Then edit /etc/dhcp/dhcpd.conf

ddns-update-style none;
option domain-name "cobo.serv";
option domain-name-servers 192.168.40.1;

default-lease-time 600;
max-lease-time 7200;

authoritative;

log-facility local7;

subnet 192.168.0.0 netmask 255.255.0.0 {
  range 192.168.40.80 192.168.40.90;
  option routers 192.168.40.1;
  option subnet-mask 255.255.255.0;
  option broadcast-address 192.168.40.254;
  option domain-name-servers 192.168.40.1;
  option ntp-servers 192.168.40.1;
}

# CoBo

host cobo02e0 {
  hardware ethernet 00:0A:35:00:00:00;
  fixed-address 192.168.40.40;
  option host-name "cobo02e0";
}

host cobo02e1 {
  hardware ethernet 00:0A:35:00:00:01;
  fixed-address 192.168.40.41;
  option host-name "cobo02e1";
}

host rcobo {
hardware ethernet 00:0A:35:02:2A:C5;
fixed-address 192.168.40.46;
option host-name "rcobo";
}

host vxcobo {
  hardware ethernet 00:0A:35:01:02:04;
  fixed-address 192.168.40.45;
  option host-name "cobovx";
}

host dev-workstation {
hardware ethernet 01:02:03:04:05:06:07;
fixed-address 192.168.40.47;
option host-name "dev-workstation";
}

The dev-workstation entry in the DHCP config file is useful to have. This machine can be used to test or debug CoBo software that is network related.

Finally run the following to launch the dhcp daemon:

sudo service isc-dhcp-server start
