KSZ8851 16Bit BSP User’s Manual
1 Overview
The KSZ8851 BSP is developed under Renesas M16C/62P microprocessor
1
ith
Renesas HEW (High-performance Embedded Workshop) IDE.
The KSZ8851 BSP
2
contains the KSZ8851 driver and OpenTCP
3
protocol stack ith
no OS (Operating System) involved.
This manual is divided into t o parts. The first part describes ho to run
KSZ8851 BSP ith OpenTCP 1.0.4 on Micrel KSZ8851-16MQL demo board.
The second part describes ho to install, and build KSZ8851 BSP by using the
Renesas SKP16C62P StarterKit Plus (SKP).
→ NOTE: KSZ8851 BSP works for Micrel KSZ8851-1 MQL demo board.
1
Please reference the M16C6 _Hardware_Manual from SKP CD for detail information about M16C/62P microprocessor via
the website www.renesas.com..
2
BSP is Board Support Package.
OpenTCP® is a license and royalty free TCP/IP stack available to the public. It was created by Viola Systems in Finland
(www.violasystems.com). The code is supported and distributed via the website www.opentcp.org.
Please reference the OpenTCP_App_Note manual for detail information about OpenTCP protocol stack.

CLI Commands
The KSZ8851 BSP provides a set of CLI commands to help user to debug
KSZ8851 device through the RS-232 serial port from your host laptop.
.1 Connecting a Serial Cable for the Terminal Emulator
Connect the serial port of the laptop and serial port of the KSZ8851 demo
board via a RS-232 cable.
After completed of serial connection, set up the communications soft are.
Any communication soft are for personal computer communications can be used
(Hyper terminal, Windo s terminal and etc.).
→ NOTE: The HyperTerminal serial port setup is 38400 8-N-1.

3 Running the OpenTCP Demo
3.1 Setting the Target IP
In order to use the demo, you must first assign an IP address to the
target. The KSZ8851 demo board is assigned a fix IP address 192.168.1.1,
and if you connect one of Ethernet port from KSZ8851 target to your
laptop. You should use an IP number on the same sub-net as you laptop.
For example, set the IP address of your laptop is 192.168.1.10
(Figure 3-2-1).
→ Note: If you want to use a IP address other than this, you need to edit the gui_demo.c file
and rebuild your pro ect.

TCP GUI Windo ill come up. Change the IP address in the upper left-hand
corner of the indo by clicking on the IP address button (Figure 3-4-1).

No click the "Establish connection" button in order to open a TCP and
UDP connection to your target board. If a successful connection is made,
the LCD on the target board ill read "Conn Est" meaning connection
established. The demo has been set up so that the OpenTCP stack ill
close a socket if it remains inactive for more than 2 minutes.
To rite to the LCD, simply type in the edit boxes (one for each line on
the LCD) and click the "Send" button. This sends the LCD text using the
TCP socket it opened hen the connection as established.
When a button is pressed on the target board, that info is also sent via
the TCP connection to the indo s program and the corresponding picture
of the button on the GUI ill change.
To send/receive UDP packets, click the "Start Streaming" button. This
ill send a TCP packet to the target board telling it to start sending
the current A2D value of the pot via a UDP packet every time it changes.
Also, hen the slider bar on the GUI is moved, the ne value is send to
the target board via UDP packets and the value is displayed on the LCD.

program that simplifies and expedites the evaluation and testing of the
KSZ8851. Three separate Windo tabs provide menu selections to check the
PHY’s link status and capabilities; perform cable diagnostics and integrity
check on transmit and receive datapaths.
To launch the LinkMD program, navigate to the directory ith the Micrel
LinkMD soft are (OpenTCP_10 \LinkMD GUI Demo) and double click on the
LinkMD.exe file. The LinkMD program ill start and display the Capabilities
menu page. The other t o menu pages are Diagnostics and PHY. Common to all

Figure 4-1 , provides the follo ing basic link status and settings for the
KSZ8851.
• Link Status section sho s the current link speed, duplex, MDI/MDIX and
polarity settings of the KSZ8851. If there is no link, these four
fields are dimmed to indicate no status.
• Advertised Capabilities and Link Partner Capabilities sections sho
the speed, duplex and full duplex flo control capabilities of the
KSZ8851 and its link partner. KSZ8851 capabilities are programmable.
Its link partner capabilities are read only, and dimmed to indicate no
capabilities hen there is no link.
• Crossover option allo s the PHY to be set in HP Auto-MDIX for
automatic detection and correction for straight through and crossover
cabling, or forced to either MDI or MDIX mode.
To read the latest PHY status, press the Refresh button.
To configure the PHY, set the desired settings and press the Update button.

4. Diagnostics Tab
The Diagnostics Tab provides the menu page to check the cable status and the
integrity of transmit and receive datapaths. These t o selections are
provided by the cable diagnostic test and the TX/RX traffic test,
respectively.
Cable Diagnostic Test
The cable diagnostic test is enabled only hen there is no link to the
KSZ8851 PHY. This test provides the follo ing cable information for the
differential pairs connected to pins {1,2} and {3,6} of the RJ-45 jack.
• Status: Indicates hether the differential pair is Open, Short, or
Unknown (no link and no cable test conducted). If there
is a physical link, Status is Good.
• Length: Provides approximate distance in meters to the open or
short cable fault. If there is a physical link, Length has
no meaning and displays an empty field.
To run the cable diagnostic test, press the Test button.
Figure 4-2 sho s the sample test results of the cable diagnostic test here
a 4 meters short and 3 meters open ere found on the differential pairs
connected to pins {1,2} and {3,6} of the RJ-45 jack, respectively.
