Installing the Software

  1. Create a directory and unzip the Linux driver/application archive file to that directory.
  2. In the directory that you created, login as root by typing su.
  3. Type your root password.
  4. Type make to compile the driver and the application.
  5. Type ./ install to install the Linux driver.
Note: You will get the following error messages when you install the driver for the first time: 
ERROR: Module altera_dma does not exist in /proc/modules.
