EP80579 Integrated Processor—Runtime Configuration

Intel

EP80579 Software Drivers for Embedded Applications on FreeBSD*

GSG September 2009

22 Order Number: 320152-005US

5.1.3 FreeBSD Sample Codelet

A codelet is provided to demonstrate how a sample application interfaces with the

Controller Area Network driver. This codelet is intended to run on an Intel

EP80579

Integrated Processor with Intel

QuickAssist Technology Development Board with

FreeBSD installed. The EP80579 Embedded Software kernel should also be installed,

but the codelet works even if it is not. Run the codelet as follows:

Note: In order to run this application, make sure a loopback CAN cable is connected to CAN 0

and CAN 1 port through CAN header. For additional details, refer to the Readme

document location in /EP805XX_release/Embedded/codelet/CAN.

1. Login as root. Root permissions are required for all operations.

2. Open a terminal window, change directory to /EP805XX_release/Embedded/

codelet/CAN and execute the bash script. Do not move the script to another

location.

[root@localhost ˜]# ./install.csh

The script checks for the Controller Area Network driver and client drivers, runs all

of the makefiles in the correct order, loads the client driver, and runs the

application.

The application output can be viewed in the terminal window.

3. Client driver output can be viewed in a second terminal window by printing

/var/log/ messages as follows:

[root@localhost ˜]# tail -f /var/log/messages

4. For information about the CAN codelet, refer to the Readme document located at

/EP805XX_release/Embedded/codelet/CAN.

5.2 Enhanced Direct Memory Access Driver

5.2.1 FreeBSD Compilation Instructions

All source files for the FreeBSD release of the Enhanced Direct Memory Access (EDMA)

driver are located in the following directory within the FreeBSD compatible EP80579

embedded software drivers release:

/EP805XX_release/Embedded/src/EDMA

Compilation of the FreeBSD EDMA driver separately from the rest of the software

package is possible. Change to the /EP805XX_release/Embedded/src/EDMA directory

and execute the following commands:

make clean

make

make install (this will install the driver for persistency)

The EDMA driver compiles, is installed, and the resulting dma.ko file is placed in the

/EP805XX_release/Embedded/build directory.

5.2.2 FreeBSD Module Load/Unload Instructions

Note: This step is not necessary if the make install command above succeeded. This is only

necessary to understand how to load and unload this driver individually.
