1.1 PRODUCT OVERVIEW
|
|
|
|
The CS8900-based ISA Ethernet Adapters from Cirrus Logic follow
|
|
IEEE 802.3 standards and support half or full-duplex operation in ISA bus
|
|
computers on 10 Mbps Ethernet networks. The adapters are designed for operation
|
|
in 16-bit ISA or EISA bus expansion slots and are available in
|
|
10BaseT-only or 3-media configurations (10BaseT, 10Base2, and AUI for 10Base-5
|
|
or fiber networks).
|
|
|
|
CS8920-based adapters are similar to the CS8900-based adapter with additional
|
|
features for Plug and Play (PnP) support and Wakeup Frame recognition. As
|
|
such, the configuration procedures differ somewhat between the two types of
|
|
adapters. Refer to the "Adapter Configuration" section for details on
|
|
configuring both types of adapters.
|
|
|
|
|
|

2.0 ADAPTER INSTALLATION and CONFIGURATION
|
|
===============================================================================
|
|
|
|
Both the CS8900 and CS8920-based adapters can be configured using parameters
|
|
stored in an on-board EEPROM. You must use the DOS-based CS8900/20 Setup
|
|
Utility if you want to change the adapter's configuration in EEPROM.
|
|
|
|
When loading the driver as a module, you can specify many of the adapter's
|
|
configuration parameters on the command-line to override the EEPROM's settings
|
|
or for interface configuration when an EEPROM is not used. (CS8920-based
|
|
adapters must use an EEPROM.) See Section 3.0 LOADING THE DRIVER AS A MODULE.
|
|
|
|
Since the CS8900/20 Setup Utility is a DOS-based application, you must install
|
|
and configure the adapter in a DOS-based system using the CS8900/20 Setup
|
|
Utility before installation in the target LINUX system. (Not required if
|
|
installing a CS8900-based adapter and the default configuration is acceptable.)
|
|
|
|
|
|
2.1 CS8900-BASED ADAPTER CONFIGURATION
|
|
|
|
CS8900-based adapters shipped from Cirrus Logic have been configured
|
|
with the following "default" settings:
|
|
|
|
Operation Mode: Memory Mode
|
|
IRQ: 10
|
|
Base I/O Address: 300
|
|
Memory Base Address: D0000
|
|
Optimization: DOS Client
|
|
Transmission Mode: Half-duplex
|
|
BootProm: None
|
|
Media Type: Autodetect (3-media cards) or
|
|
10BASE-T (10BASE-T only adapter)
|
|
|
|
You should only change the default configuration settings if conflicts with
|
|
another adapter exists. To change the adapter's configuration, run the
|
|
CS8900/20 Setup Utility.
|
|
|
|
|
|
2.2 CS8920-BASED ADAPTER CONFIGURATION
|
|
|
|
CS8920-based adapters are shipped from Cirrus Logic configured as Plug
|
|
and Play (PnP) enabled. However, since the cs89x0 driver does NOT
|
|
support PnP, you must install the CS8920 adapter in a DOS-based PC and
|
|
run the CS8900/20 Setup Utility to disable PnP and configure the
|
|
adapter before installation in the target Linux system. Failure to do
|
|
this will leave the adapter inactive and the driver will be unable to
|
|
communicate with the adapter.
|
|

****************************************************************
|
|
* CS8920-BASED ADAPTERS: *
|
|
* *
|
|
* CS8920-BASED ADAPTERS ARE PLUG and PLAY ENABLED BY DEFAULT. *
|
|
* THE CS89X0 DRIVER DOES NOT SUPPORT PnP. THEREFORE, YOU MUST *
|
|
* RUN THE CS8900/20 SETUP UTILITY TO DISABLE PnP SUPPORT AND *
|
|
* TO ACTIVATE THE ADAPTER. *

3.0 LOADING THE DRIVER AS A MODULE
|
|
===============================================================================
|
|
|
|
If the driver is compiled as a loadable module, you can load the driver module
|
|
with the 'modprobe' command. Many of the adapter's configuration parameters can
|
|
be specified as command-line arguments to the load command. This facility
|
|
provides a means to override the EEPROM's settings or for interface
|
|
configuration when an EEPROM is not used.
|
|
|
|
Example:
|
|
|
|
insmod cs89x0.o io=0x200 irq=0xA media=aui
|
|
|
|
This example loads the module and configures the adapter to use an IO port base
|
|
address of 200h, interrupt 10, and use the AUI media connection. The following
|
|
configuration options are available on the command line:
|
|
|
|
* io=### - specify IO address (200h-360h)
|
|
* irq=## - specify interrupt level
|
|
* use_dma=1 - Enable DMA
|
|
* dma=# - specify dma channel (Driver is compiled to support
|
|
Rx DMA only)
|
|
* dmasize=# (16 or 64) - DMA size 16K or 64K. Default value is set to 16.
|
|
* media=rj45 - specify media type
|
|
or media=bnc
|
|
or media=aui
|
|
or media=auto
|
|
* duplex=full - specify forced half/full/autonegotiate duplex
|
|
or duplex=half
|
|
or duplex=auto
|
|
* debug=# - debug level (only available if the driver was compiled
|
|
for debugging)
|
|
|
|
NOTES:
|
|
|
|
a) If an EEPROM is present, any specified command-line parameter
|
|
will override the corresponding configuration value stored in
|
|
EEPROM.
|
|
|
|
b) The "io" parameter must be specified on the command-line.
|
|
|
|
c) The driver's hardware probe routine is designed to avoid
|
|
writing to I/O space until it knows that there is a cs89x0
|
|
card at the written addresses. This could cause problems
|
|
with device probing. To avoid this behaviour, add one
|
|
to the `io=' module parameter. This doesn't actually change
|
|
the I/O address, but it is a flag to tell the driver
|
|
to partially initialise the hardware before trying to
|
|
identify the card. This could be dangerous if you are
|
|
not sure that there is a cs89x0 card at the provided address.
|
|
|
|
For example, to scan for an adapter located at IO base 0x300,
|
|
specify an IO address of 0x301.
|
|
|
|
d) The "duplex=auto" parameter is only supported for the CS8920.
|
|
|
|
e) The minimum command-line configuration required if an EEPROM is
|
|
not present is:
|
|
|
|
io
|
|
irq
|
|
media type (no autodetect)
|
|
|
|
f) The following additional parameters are CS89XX defaults (values
|
|
used with no EEPROM or command-line argument).
|
|
|
|
* DMA Burst = enabled
|
|
* IOCHRDY Enabled = enabled
|
|
* UseSA = enabled
|
|
* CS8900 defaults to half-duplex if not specified on command-line
|
|
* CS8920 defaults to autoneg if not specified on command-line
|
|
* Use reset defaults for other config parameters
|
|
* dma_mode = 0
|
|
|
|
g) You can use ifconfig to set the adapter's Ethernet address.
|
|
|
|
h) Many Linux distributions use the 'modprobe' command to load
|
|
modules. This program uses the '/etc/conf.modules' file to
|
|
determine configuration information which is passed to a driver
|
|
module when it is loaded. All the configuration options which are
|
|
described above may be placed within /etc/conf.modules.
|
|
|
|
For example:
|
|
|
|
> cat /etc/conf.modules
|
|
...
|
|
alias eth0 cs89x0
|
|
options cs89x0 io=0x0200 dma=5 use_dma=1
|
|
...
|
|
|
|
In this example we are telling the module system that the
|
|
ethernet driver for this machine should use the cs89x0 driver. We
|
|
are asking 'modprobe' to pass the 'io', 'dma' and 'use_dma'
|
|
arguments to the driver when it is loaded.
|
|
|
|
i) Cirrus recommend that the cs89x0 use the ISA DMA channels 5, 6 or
|
|
7. You will probably find that other DMA channels will not work.
|
|
|
|
j) The cs89x0 supports DMA for receiving only. DMA mode is
|
|
significantly more efficient. Flooding a 400 MHz Celeron machine
|
|
with large ping packets consumes 82% of its CPU capacity in non-DMA
|
|
mode. With DMA this is reduced to 45%.
|
|
|
|
k) If your Linux kernel was compiled with inbuilt plug-and-play
|
|
support you will be able to find information about the cs89x0 card
|
|
with the command
|
|
|
|
cat /proc/isapnp
|
|
|
|
l) If during DMA operation you find erratic behavior or network data
|
|
corruption you should use your PC's BIOS to slow the EISA bus clock.
|
|
|
|
m) If the cs89x0 driver is compiled directly into the kernel
|
|
(non-modular) then its I/O address is automatically determined by
|
|
ISA bus probing. The IRQ number, media options, etc are determined
|
|
from the card's EEPROM.
|
|
|
|
n) If the cs89x0 driver is compiled directly into the kernel, DMA
|
|
mode may be selected by providing the kernel with a boot option
|
|
'cs89x0_dma=N' where 'N' is the desired DMA channel number (5, 6 or 7).
|
|
|
|
Kernel boot options may be provided on the LILO command line:
|
|
|
|
LILO boot: linux cs89x0_dma=5
|
|
|
|
or they may be placed in /etc/lilo.conf:
|
|
|
|
image=/boot/bzImage-2.3.48
|
|
append="cs89x0_dma=5"
|
|
label=linux
|
|
root=/dev/hda5
|
|
read-only
|
|
|
|
The DMA Rx buffer size is hardwired to 16 kbytes in this mode.
|
|
(64k mode is not available).
|
|
|
|
|
|
4.0 COMPILING THE DRIVER
|
|
===============================================================================
|
|
|
|
The cs89x0 driver can be compiled directly into the kernel or compiled into
|
|
a loadable device driver module.
|
|
|
|
|
|
4.1 COMPILING THE DRIVER AS A LOADABLE MODULE
|
|
|
|
To compile the driver into a loadable module, use the following command
|
|
(single command line, without quotes):
|
|
|
|
"gcc -D__KERNEL__ -I/usr/src/linux/include -I/usr/src/linux/net/inet -Wall
|
|
-Wstrict-prototypes -O2 -fomit-frame-pointer -DMODULE -DCONFIG_MODVERSIONS
|
|
-c cs89x0.c"
|
|
|
|
4.2 COMPILING THE DRIVER TO SUPPORT MEMORY MODE
|
|
|
|
Support for memory mode was not carried over into the 2.3 series kernels.
|
|
|
|
4.3 COMPILING THE DRIVER TO SUPPORT Rx DMA
|
|
|
|
The compile-time optionality for DMA was removed in the 2.3 kernel
|
|
series. DMA support is now unconditionally part of the driver. It is
|
|
enabled by the 'use_dma=1' module option.
|
|
|
|
4.4 COMPILING THE DRIVER INTO THE KERNEL
|
|
|
|
If your Linux distribution already has support for the cs89x0 driver
|
|
then simply copy the source file to the /usr/src/linux/drivers/net
|
|
directory to replace the original ones and run the make utility to
|
|
rebuild the kernel. See Step 3 for rebuilding the kernel.
|
|
|
|
If your Linux does not include the cs89x0 driver, you need to edit three
|
|
configuration files, copy the source file to the /usr/src/linux/drivers/net
|
|
directory, and then run the make utility to rebuild the kernel.
|
|
|
|
1. Edit the following configuration files by adding the statements as
|
|
indicated. (When possible, try to locate the added text to the section of the
|
|
file containing similar statements).
|
|
|
|
|
|
a.) In /usr/src/linux/drivers/net/Config.in, add:
|
|
|
|
tristate 'CS89x0 support' CONFIG_CS89x0
|
|
|
|
Example:
|
|
|
|
if [ "$CONFIG_EXPERIMENTAL" = "y" ]; then
|
|
tristate 'ICL EtherTeam 16i/32 support' CONFIG_ETH16I
|
|
fi
|
|
|
|
tristate 'CS89x0 support' CONFIG_CS89x0
|
|
|
|
tristate 'NE2000/NE1000 support' CONFIG_NE2000
|
|
if [ "$CONFIG_EXPERIMENTAL" = "y" ]; then
|
|
tristate 'NI5210 support' CONFIG_NI52
|
|
|
|
|
|
b.) In /usr/src/linux/drivers/net/Makefile, add the following lines:
|
|
|
|
ifeq ($(CONFIG_CS89x0),y)
|
|
L_OBJS += cs89x0.o
|
|
else
|
|
ifeq ($(CONFIG_CS89x0),m)
|
|
M_OBJS += cs89x0.o
|
|
endif
|
|
endif
|
|
|
|
|
|
c.) In /linux/drivers/net/Space.c file, add the line:
|
|
|
|
extern int cs89x0_probe(struct device *dev);
|
|
|
|
|
|
Example:
|
|
|
|
extern int ultra_probe(struct device *dev);
|
|
extern int wd_probe(struct device *dev);
|
|
extern int el2_probe(struct device *dev);
|
|
|
|
extern int cs89x0_probe(struct device *dev);
|
|
|
|
extern int ne_probe(struct device *dev);
|
|
extern int hp_probe(struct device *dev);
|
|
extern int hp_plus_probe(struct device *dev);
|
|
|
|
|
|
Also add:
|
|
|
|
#ifdef CONFIG_CS89x0
|
|
{ cs89x0_probe,0 },
|
|
#endif
|
|
|
|
|
|
2.) Copy the driver source files (cs89x0.c and cs89x0.h)
|
|
into the /usr/src/linux/drivers/net directory.
|
|
|
|
|
|
3.) Go to /usr/src/linux directory and run 'make config' followed by 'make'
|
|
(or make bzImage) to rebuild the kernel.
|
|
|
|
4.) Use the DOS 'setup' utility to disable plug and play on the NIC.
|
|
|

5.0 TESTING AND TROUBLESHOOTING
|
|
===============================================================================
|
|
|
|
5.1 KNOWN DEFECTS and LIMITATIONS
|
|
|
|
Refer to the RELEASE.TXT file distributed as part of this archive for a list of
|
|
known defects, driver limitations, and work arounds.
|
|
|
|
|
|
5.2 TESTING THE ADAPTER
|
|
|
|
Once the adapter has been installed and configured, the diagnostic option of
|
|
the CS8900/20 Setup Utility can be used to test the functionality of the
|
|
adapter and its network connection. Use the diagnostics 'Self Test' option to
|
|
test the functionality of the adapter with the hardware configuration you have
|
|
assigned. You can use the diagnostics 'Network Test' to test the ability of the
|
|
adapter to communicate across the Ethernet with another PC equipped with a
|
|
CS8900/20-based adapter card (it must also be running the CS8900/20 Setup
|
|
Utility).
|
|
|
|
NOTE: The Setup Utility's diagnostics are designed to run in a
|
|
DOS-only operating system environment. DO NOT run the diagnostics
|
|
from a DOS or command prompt session under Windows 95, Windows NT,
|
|
OS/2, or other operating system.
|
|
|
|
To run the diagnostics tests on the CS8900/20 adapter:
|
|
|
|
1.) Boot DOS on the PC and start the CS8900/20 Setup Utility.
|
|
|
|
2.) The adapter's current configuration is displayed. Hit the ENTER key to
|
|
get to the main menu.
|
|
|
|
4.) Select 'Diagnostics' (ALT-G) from the main menu.
|
|
* Select 'Self-Test' to test the adapter's basic functionality.
|
|
* Select 'Network Test' to test the network connection and cabling.
|
|
|
|
|
|
5.2.1 DIAGNOSTIC SELF-TEST
|
|
|
|
The diagnostic self-test checks the adapter's basic functionality as well as
|
|
its ability to communicate across the ISA bus based on the system resources
|
|
assigned during hardware configuration. The following tests are performed:
|
|
|
|
* IO Register Read/Write Test
|
|
The IO Register Read/Write test insures that the CS8900/20 can be
|
|
accessed in IO mode, and that the IO base address is correct.
|
|
|
|
* Shared Memory Test
|
|
The Shared Memory test insures the CS8900/20 can be accessed in memory
|
|
mode and that the range of memory addresses assigned does not conflict
|
|
with other devices in the system.
|
|
|
|
* Interrupt Test
|
|
The Interrupt test insures there are no conflicts with the assigned IRQ
|
|
signal.
|
|
|
|
* EEPROM Test
|
|
The EEPROM test insures the EEPROM can be read.
|
|
|
|
* Chip RAM Test
|
|
The Chip RAM test insures the 4K of memory internal to the CS8900/20 is
|
|
working properly.
|
|
|
|
* Internal Loop-back Test
|
|
The Internal Loop Back test insures the adapter's transmitter and
|
|
receiver are operating properly. If this test fails, make sure the
|
|
adapter's cable is connected to the network (check for LED activity for
|
|
example).
|
|
|
|
* Boot PROM Test
|
|
The Boot PROM test insures the Boot PROM is present, and can be read.
|
|
Failure indicates the Boot PROM was not successfully read due to a
|
|
hardware problem or due to a conflicts on the Boot PROM address
|
|
assignment. (Test only applies if the adapter is configured to use the
|
|
Boot PROM option.)
|
|
|
|
Failure of a test item indicates a possible system resource conflict with
|
|
another device on the ISA bus. In this case, you should use the Manual Setup
|
|
option to reconfigure the adapter by selecting a different value for the system
|
|
resource that failed.
|
|
|
|
|
|
5.2.2 DIAGNOSTIC NETWORK TEST
|
|
|
|
The Diagnostic Network Test verifies a working network connection by
|
|
transferring data between two CS8900/20 adapters installed in different PCs
|
|
on the same network. (Note: the diagnostic network test should not be run
|
|
between two nodes across a router.)
|
|
|
|
This test requires that each of the two PCs have a CS8900/20-based adapter
|
|
installed and have the CS8900/20 Setup Utility running. The first PC is
|
|
configured as a Responder and the other PC is configured as an Initiator.
|
|
Once the Initiator is started, it sends data frames to the Responder which
|
|
returns the frames to the Initiator.
|
|
|
|
The total number of frames received and transmitted are displayed on the
|
|
Initiator's display, along with a count of the number of frames received and
|
|
transmitted OK or in error. The test can be terminated anytime by the user at
|
|
either PC.
|
|
|
|
To setup the Diagnostic Network Test:
|
|
|
|
1.) Select a PC with a CS8900/20-based adapter and a known working network
|
|
connection to act as the Responder. Run the CS8900/20 Setup Utility
|
|
and select 'Diagnostics -> Network Test -> Responder' from the main
|
|
menu. Hit ENTER to start the Responder.
|
|
|
|
2.) Return to the PC with the CS8900/20-based adapter you want to test and
|
|
start the CS8900/20 Setup Utility.
|
|
|
|
3.) From the main menu, Select 'Diagnostic -> Network Test -> Initiator'.
|
|
Hit ENTER to start the test.
|
|
|
|
You may stop the test on the Initiator at any time while allowing the Responder
|
|
to continue running. In this manner, you can move to additional PCs and test
|
|
them by starting the Initiator on another PC without having to stop/start the
|
|
Responder.
|
|
|
|
|
|
|
|
5.3 USING THE ADAPTER'S LEDs
|
|
|
|
The 2 and 3-media adapters have two LEDs visible on the back end of the board
|
|
located near the 10Base-T connector.
|
|
|
|
Link Integrity LED: A "steady" ON of the green LED indicates a valid 10Base-T
|
|
connection. (Only applies to 10Base-T. The green LED has no significance for
|
|
a 10Base-2 or AUI connection.)
|
|
|
|
TX/RX LED: The yellow LED lights briefly each time the adapter transmits or
|
|
receives data. (The yellow LED will appear to "flicker" on a typical network.)
|
|
|
|
|
|
5.4 RESOLVING I/O CONFLICTS
|
|
|
|
An IO conflict occurs when two or more adapter use the same ISA resource (IO
|
|
address, memory address or IRQ). You can usually detect an IO conflict in one
|
|
of four ways after installing and or configuring the CS8900/20-based adapter:
|
|
|
|
1.) The system does not boot properly (or at all).
|
|
|
|
2.) The driver cannot communicate with the adapter, reporting an "Adapter
|
|
not found" error message.
|
|
|
|
3.) You cannot connect to the network or the driver will not load.
|
|
|
|
4.) If you have configured the adapter to run in memory mode but the driver
|
|
reports it is using IO mode when loading, this is an indication of a
|
|
memory address conflict.
|
|
|
|
If an IO conflict occurs, run the CS8900/20 Setup Utility and perform a
|
|
diagnostic self-test. Normally, the ISA resource in conflict will fail the
|
|
self-test. If so, reconfigure the adapter selecting another choice for the
|
|
resource in conflict. Run the diagnostics again to check for further IO
|
|
conflicts.
|
|
|
|
In some cases, such as when the PC will not boot, it may be necessary to remove
|
|
the adapter and reconfigure it by installing it in another PC to run the
|
|
CS8900/20 Setup Utility. Once reinstalled in the target system, run the
|
|
diagnostics self-test to ensure the new configuration is free of conflicts
|
|
before loading the driver again.
|
|
|
|
When manually configuring the adapter, keep in mind the typical ISA system
|
|
resource usage as indicated in the tables below.
