DRIVER LOADING
|
||||
=====================
|
||||
|
||||
o. Copy the firmware image (e.g. usb8388.bin) to /lib/firmware/
|
||||
|
||||
o. Load driver by using the following command:
|
||||
|
||||
insmod usb8388.ko [fw_name=usb8388.bin]
|
||||
|
||||
=========================
|
||||
ETHTOOL
|
||||
=========================
|
||||
|
||||
|
||||
Use the -i option to retrieve version information from the driver.
|
||||
|
||||
# ethtool -i eth0
|
||||
driver: libertas
|
||||
version: COMM-USB8388-318.p4
|
||||
firmware-version: 5.110.7
|
||||
bus-info:
|
||||
|
||||
Use the -e option to read the EEPROM contents of the card.
|
||||
|
||||
Usage:
|
||||
ethtool -e ethX [raw on|off] [offset N] [length N]
|
||||
|
||||
-e retrieves and prints an EEPROM dump for the specified ethernet
|
||||
device. When raw is enabled, then it dumps the raw EEPROM data
|
||||
to stdout. The length and offset parameters allow dumping cer-
|
||||
tain portions of the EEPROM. Default is to dump the entire EEP-
|
||||
ROM.
|
||||
|
||||
# ethtool -e eth0 offset 0 length 16
|
||||
Offset Values
|
||||
------ ------
|
||||
0x0000 38 33 30 58 00 00 34 f4 00 00 10 00 00 c4 17 00
|
||||

|
||||
DEBUGFS COMMANDS
|
||||
========================
|
||||
|
||||
those commands are used via debugfs interface
|
||||
|
||||
===========
|
||||
rdmac
|
||||
rdbbp
|
||||
rdrf
|
||||
These commands are used to read the MAC, BBP and RF registers from the
|
||||
card. These commands take one parameter that specifies the offset
|
||||
location that is to be read. This parameter must be specified in
|
||||
hexadecimal (its possible to precede preceding the number with a "0x").
|
||||
|
||||
Path: /sys/kernel/debug/libertas_wireless/ethX/registers/
|
||||
|
||||
Usage:
|
||||
echo "0xa123" > rdmac ; cat rdmac
|
||||
echo "0xa123" > rdbbp ; cat rdbbp
|
||||
echo "0xa123" > rdrf ; cat rdrf
|
||||
wrmac
|
||||
wrbbp
|
||||
wrrf
|
||||
These commands are used to write the MAC, BBP and RF registers in the
|
||||
card. These commands take two parameters that specify the offset
|
||||
location and the value that is to be written. This parameters must
|
||||
be specified in hexadecimal (its possible to precede the number
|
||||
with a "0x").
|
||||
|
||||
Usage:
|
||||
echo "0xa123 0xaa" > wrmac
|
||||
echo "0xa123 0xaa" > wrbbp
|
||||
echo "0xa123 0xaa" > wrrf
|
||||
|
||||
sleepparams
|
||||
This command is used to set the sleepclock configurations
|
||||
|
||||
Path: /sys/kernel/debug/libertas_wireless/ethX/
|
||||
|
||||
Usage:
|
||||
cat sleepparams: reads the current sleepclock configuration
|
||||
|
||||
echo "p1 p2 p3 p4 p5 p6" > sleepparams: writes the sleepclock configuration.
|
||||
|
||||
where:
|
||||
p1 is Sleep clock error in ppm (0-65535)
|
||||
p2 is Wakeup offset in usec (0-65535)
|
||||
p3 is Clock stabilization time in usec (0-65535)
|
||||
p4 is Control periodic calibration (0-2)
|
||||
p5 is Control the use of external sleep clock (0-2)
|
||||
p6 is reserved for debug (0-65535)
|
||||
|
||||
subscribed_events
|
||||
|
||||
The subscribed_events directory contains the interface for the
|
||||
subscribed events API.
|
||||
|
||||
Path: /sys/kernel/debug/libertas_wireless/ethX/subscribed_events/
|
||||
|
||||
Each event is represented by a filename. Each filename consists of the
|
||||
following three fields:
|
||||
Value Frequency Subscribed
|
||||
|
||||
To read the current values for a given event, do:
|
||||
cat event
|
||||
To set the current values, do:
|
||||
echo "60 2 1" > event
|
||||
|
||||
Frequency field specifies the reporting frequency for this event.
|
||||
If it is set to 0, then the event is reported only once, and then
|
||||
automatically unsubscribed. If it is set to 1, then the event is
|
||||
reported every time it occurs. If it is set to N, then the event is
|
||||
reported every Nth time it occurs.
|
||||
|
||||
beacon_missed
|
||||
Value field specifies the number of consecutive missing beacons which
|
||||
triggers the LINK_LOSS event. This event is generated only once after
|
||||
which the firmware resets its state. At initialization, the LINK_LOSS
|
||||
event is subscribed by default. The default value of MissedBeacons is
|
||||
60.
|
||||
|
||||
failure_count
|
||||
Value field specifies the consecutive failure count threshold which
|
||||
triggers the generation of the MAX_FAIL event. Once this event is
|
||||
generated, the consecutive failure count is reset to 0.
|
||||
At initialization, the MAX_FAIL event is NOT subscribed by
|
||||
default.
|
||||
|
||||
high_rssi
|
||||
This event is generated when the average received RSSI in beacons goes
|
||||
above a threshold, specified by Value.
|
||||
|
||||
low_rssi
|
||||
This event is generated when the average received RSSI in beacons goes
|
||||
below a threshold, specified by Value.
|
||||
|
||||
high_snr
|
||||
This event is generated when the average received SNR in beacons goes
|
||||
above a threshold, specified by Value.
|
||||
|
||||
low_snr
|
||||
This event is generated when the average received SNR in beacons goes
|
||||
below a threshold, specified by Value.
|
||||
|
||||
extscan
|
||||
This command is used to do a specific scan.
|
||||
|
||||
Path: /sys/kernel/debug/libertas_wireless/ethX/
|
||||
|
||||
Usage: echo "SSID" > extscan
|
||||
|
||||
Example:
|
||||
echo "LINKSYS-AP" > extscan
|
||||
|
||||
To see the results of use getscantable command.
|
||||
|
||||
getscantable
|
||||
|
||||
Display the current contents of the driver scan table (ie. get the
|
||||
scan results).
|
||||
|
||||
Path: /sys/kernel/debug/libertas_wireless/ethX/
|
||||
|
||||
Usage:
|
||||
cat getscantable
|
||||
|
||||
setuserscan
|
||||
Initiate a customized scan and retrieve the results
|
||||
|
||||
|
||||
Path: /sys/kernel/debug/libertas_wireless/ethX/
|
||||
|
||||
Usage:
|
||||
echo "[ARGS]" > setuserscan
|
||||
|
||||
where [ARGS]:
|
||||
|
||||
bssid=xx:xx:xx:xx:xx:xx specify a BSSID filter for the scan
|
||||
ssid="[SSID]" specify a SSID filter for the scan
|
||||
keep=[0 or 1] keep the previous scan results (1), discard (0)
|
||||
dur=[scan time] time to scan for each channel in milliseconds
|
||||
type=[1,2,3] BSS type: 1 (Infra), 2(Adhoc), 3(Any)
|
||||
|
||||
Any combination of the above arguments can be supplied on the command
|
||||
line. If dur tokens are absent, the driver default setting will be used.
|
||||
The bssid and ssid fields, if blank, will produce an unfiltered scan.
|
||||
The type field will default to 3 (Any) and the keep field will default
|
||||
to 0 (Discard).
|
||||
|
||||
Examples:
|
||||
1) Perform a passive scan on all channels for 20 ms per channel:
|
||||
echo "dur=20" > setuserscan
|
||||
|
||||
2) Perform an active scan for a specific SSID:
|
||||
echo "ssid="TestAP"" > setuserscan
|
||||
|
||||
3) Scan all available channels (B/G, A bands) for a specific BSSID, keep
|
||||
the current scan table intact, update existing or append new scan data:
|
||||
echo "bssid=00:50:43:20:12:82 keep=1" > setuserscan
|
||||
|
||||
4) Scan for all infrastructure networks.
|
||||
Keep the previous scan table intact. Update any duplicate BSSID/SSID
|
||||
matches with the new scan data:
|
||||
echo "type=1 keep=1" > setuserscan
|
||||
|
||||
All entries in the scan table (not just the new scan data when keep=1)
|
||||
will be displayed upon completion by use of the getscantable ioctl.
|
||||
|
||||
hostsleep
|
||||
This command is used to enable/disable host sleep.
|
||||
Note: Host sleep parameters should be configured using
|
||||
"ethtool -s ethX wol X" command before enabling host sleep.
|
||||
|
||||
Path: /sys/kernel/debug/libertas_wireless/ethX/
|
||||
|
||||
Usage:
|
||||
cat hostsleep: reads the current hostsleep state
|
||||
echo "1" > hostsleep : enable host sleep.
|
||||
echo "0" > hostsleep : disable host sleep
