EP80579 Software Drivers for Embedded Applications on FreeBSD*

kldunload timesync.ko

The kldstat command may be used to confirm if a module has been loaded or

unloaded:

kldstat | grep timesync

The output of the kldstat command lists all modules loaded in the system. Look for an

entry titled “timesync”.

5.5.3 FreeBSD Sample Codelet

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

1588 Hardware Assist 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:

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

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

codelet/1588 and execute the bash script. Do not move the script to another

location.

[root@localhost ˜]# ./install.csh

The script checks for the IEEE 1588 Hardware Assist 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 1588 codelet, refer to the Readme document located at

/EP805XX_release/Embedded/codelet/1588.

5.6 Global Configuration Unit and Gigabit Ethernet Driver

Two drivers complete the software features set for network connectivity on the

EP80579 integrated Gigabit Ethernet controllers; the Global Configuration Unit (GCU)

driver and the Gigabit Ethernet (GbE) driver. The GCU driver controls the MAC and

administrative activities. The GbE driver controls the network connectivity. The GbE

driver is dependent on the GCU driver.

Note: The Global Configuration Unit driver must be installed prior to installation of the Gigabit

Ethernet driver.

5.6.1 FreeBSD Compilation Instructions

All source files for the FreeBSD release of the EP80579 Global Configuration Unit driver

and Gigabit Ethernet driver are located in the following directories within the FreeBSD

compatible EP80579 embedded software drivers release:

/EP805XX_release/Embedded/src/GbE

/EP805XX_release/Embedded/src/GCU
