Installing Xilinx ISE/EDK 11.5 under Ubuntu 9.10
This guide tell how-to install Xilinx ISE and EDK under Ubuntu 9.10, using a 30-days evaluation license acquired at http://www.xilinx.com/ise_eval/index.htm.
Required tools
The EDK needs make, which must be called gmake. The easiest way is to install build essential and make a symlink from make to gmake. Futhermore fxload is needed for firmware upload and motif for the GUI.
sudo apt-get install fxload build-essential motif-clients sudo ln -s /usr/bin/make /usr/bin/gmake
If you have purchased a development board from Xilinx, use the included DVD:
cd /media/cdrom
sudo ./xsetup
If not, follow the download link at the above URL, and download the ISE Design Suite: Full DVD, which is roughly 5.6 GB and untar it:
mkdir ise
cd ise
tar -cvf Xilinx_11.1_ISE_DS_SFD.tar
cd Xilinx_11.1_ISE_DS_SFD
sudo ./xsetup
You do not need to use sudo, but if all users on the system should use EDK, it will be installed in /opt/Xilinx/ using sudo. If sudo is not used, it will be installed in /home/username/.
The installation process is straight forward, and will guide you to setting up a license in the last step. If you choose to use the 30-day trial, a browser will open the Xilinx license system, which will generate the license, download it and install it.
Start up scripts
In order to start xps the environment variable $XILINX must hold the path to ISE. To start xps type
export XILINX=/opt/Xilinx/11.1/ISE/ && /opt/Xilinx/11.1/EDK/bin/lin/xps
Cleaning up /boot by removing unused kernels (Ubuntu)
At some point /boot will be full of old kernels (if /boot is a separate partition), which makes it impossible to make a dist-upgrade and it is therefore necessary to remove some old kernels.
Start by finding you current kernel
uname -r
which will give something like
2.6.24-25-server
Now, find all installed kernels
aptitude search linux|grep linux-image | grep "i "
which will give something like
i linux-image-2.6.24-12-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-14-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-15-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-16-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-17-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-18-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-19-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-21-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-22-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-23-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-24-server - Linux kernel image for version 2.6.24 on x
i linux-image-2.6.24-25-server - Linux kernel image for version 2.6.24 on x
i linux-image-server - Linux kernel image on Server Equipment.
Purge all of these, except the one found with uname -r and linux-image-server, which is a meta package
sudo apt-get purge linux-image-2.6.24-14-server linux-image-2.6.24-15-server linux-image-2.6.24-16-server linux-image-2.6.24-17-server linux-image-2.6.24-18-server linux-image-2.6.24-19-server linux-image-2.6.24-21-server linux-image-2.6.24-22-server linux-image-2.6.24-23-server linux-image-2.6.24-24-server
The above freed 250 MB from /boot and 550 MB from / at my system.
