+===============================================================================
+ U S E R M A N U A L
+
+1) FOR DRIVER INSTALL
+
+ a) Copy sd8787.bin to /lib/firmware/mrvl/ directory,
+ create the directory if it doesn't exist.
+ b) Install WLAN driver,
+ insmod mwifiex.ko
+ c) Uninstall WLAN driver,
+ ifconfig mlanX down
+ rmmod mwifiex
+
+
+2) FOR DRIVER CONFIGURATION AND INFO
+ The configurations can be done either using the 'iw' user space
+ utility or debugfs.
+
+ a) 'iw' utility commands
+
+ Following are some useful iw commands:-
+
+iw dev mlan0 scan
+
+ This command will trigger a scan.
+ The command will then display the scan table entries
+
+iw dev mlan0 connect -w <SSID> [<freq in MHz>] [<bssid>] [key 0:abcde d:1123456789a]
+ The above command can be used to connect to an AP with a particular SSID.
+ Ap's operating frequency can be specified or even the bssid. If the AP is using
+ WEP encryption, wep keys can be specified in the command.
+ Note: Every time before connecting to an AP scan command (iw dev mlan0 scan) should be used by user.
+
+iw dev mlan0 disconnect
+ This command will be used to disconnect from an AP.
+
+
+iw dev mlan0 ibss join <SSID> <freq in MHz> [fixed-freq] [fixed-bssid] [key 0:abcde]
+ The command will be used to join or create an ibss. Optionally, operating frequency,
+ bssid and the security related parameters can be specified while joining/creating
+ and ibss.
+
+iw dev mlan0 ibss leave
+ The command will be used to leave an ibss network.
+
+iw dev mlan0 link
+ The command will be used to get the connection status. The command will return parameters
+ such as SSID, operating frequency, rx/tx packets, signal strength, tx bitrate.
+
+ Apart from the iw utility all standard configurations using the 'iwconfig' utility are also supported.
+
+ b) Debugfs interface
+
+ The debugfs interface can be used for configurations and for getting
+ some useful information from the driver.
+ The section below explains the configurations that can be
+ done.
+
+ Mount debugfs to /debugfs mount point:
+
+ mkdir /debugfs
+ mount -t debugfs debugfs /debugfs
+
+ The information is provided in /debugfs/mwifiex/mlanX/:
+
+iw reg set <country code>

+ echo " <type> <offset> [value]" > regrdwr
+ cat regrdwr
+
+ where the parameters are,
+ <type>: 1:MAC/SOC, 2:BBP, 3:RF, 4:PMIC, 5:CAU
+ <offset>: offset of register
+ [value]: value to be written
+
+ Examples:
+ echo "1 0xa060" > regrdwr : Read the MAC register
+ echo "1 0xa060 0x12" > regrdwr : Write the MAC register
+ echo "1 0xa794 0x80000000" > regrdwr
+ : Write 0x80000000 to MAC register
+rdeeprom
+ This command is used to read the EEPROM contents of the card.
+
+ Usage:
+ echo "<offset> <length>" > rdeeprom
+ cat rdeeprom
+
+ where the parameters are,
+ <offset>: multiples of 4
+ <length>: 4-20, multiples of 4
+
+ Example:
+ echo "0 20" > rdeeprom : Read 20 bytes of EEPROM data from offset 0
+
+hscfg
+ This command is used to debug/simulate host sleep feature using
+ different configuration parameters.
+
+ Usage:
+ echo "<condition> [GPIO# [gap]]]" > hscfg
+ cat hscfg
+
+ where the parameters are,
+ <condition>: bit 0 = 1 -- broadcast data
+ bit 1 = 1 -- unicast data
+ bit 2 = 1 -- mac event
+ bit 3 = 1 -- multicast data
+ [GPIO#]: pin number of GPIO used to wakeup the host.
+ GPIO pin# (e.g. 0-7) or 0xff (interface, e.g. SDIO
+ will be used instead).
+ [gap]: the gap in milliseconds between wakeup signal and
+ wakeup event or 0xff for special setting (host
+ acknowledge required) when GPIO is used to wakeup host.
+
+ Examples:
+ echo "-1" > hscfg : Cancel host sleep mode
+ echo "3" > hscfg : Broadcast and unicast data;
+ Use GPIO and gap set previously
+ echo "2 3" > hscfg : Unicast data and GPIO 3;
+ Use gap set previously
+ echo "2 1 160" > hscfg : Unicast data, GPIO 1 and gap 160 ms
+ echo "2 1 0xff" > hscfg : Unicast data, GPIO 1; Wait for host
+ to ack before sending wakeup event
+
+getlog
+ This command is used to get the statistics available in the station.
+ Usage:
+
+ cat getlog
+
+device_dump
+ This command is used to dump driver information and firmware memory
+ segments.
+ Usage:
+
+ cat fw_dump

- U S E R M A N U A L
-
-1) FOR DRIVER INSTALL
-
- a) Copy sd8787.bin to /lib/firmware/mrvl/ directory,
- create the directory if it doesn't exist.
- b) Install WLAN driver,
- insmod mwifiex.ko
- c) Uninstall WLAN driver,
- ifconfig mlanX down
- rmmod mwifiex
-
-
-2) FOR DRIVER CONFIGURATION AND INFO
- The configurations can be done either using the 'iw' user space
- utility or debugfs.
-
- a) 'iw' utility commands
-
- Following are some useful iw commands:-
-
-iw dev mlan0 scan
-
- This command will trigger a scan.
- The command will then display the scan table entries
-
-iw dev mlan0 connect -w <SSID> [<freq in MHz>] [<bssid>] [key 0:abcde d:1123456789a]
- The above command can be used to connect to an AP with a particular SSID.
- Ap's operating frequency can be specified or even the bssid. If the AP is using
- WEP encryption, wep keys can be specified in the command.
- Note: Every time before connecting to an AP scan command (iw dev mlan0 scan) should be used by user.
-
-iw dev mlan0 disconnect
- This command will be used to disconnect from an AP.
-
-
-iw dev mlan0 ibss join <SSID> <freq in MHz> [fixed-freq] [fixed-bssid] [key 0:abcde]
- The command will be used to join or create an ibss. Optionally, operating frequency,
- bssid and the security related parameters can be specified while joining/creating
- and ibss.
-
-iw dev mlan0 ibss leave
- The command will be used to leave an ibss network.
-
-iw dev mlan0 link
- The command will be used to get the connection status. The command will return parameters
- such as SSID, operating frequency, rx/tx packets, signal strength, tx bitrate.
-
- Apart from the iw utility all standard configurations using the 'iwconfig' utility are also supported.
-
- b) Debugfs interface
-
- The debugfs interface can be used for configurations and for getting
- some useful information from the driver.
- The section below explains the configurations that can be
- done.
-
- Mount debugfs to /debugfs mount point:
-
- mkdir /debugfs
- mount -t debugfs debugfs /debugfs
-
- The information is provided in /debugfs/mwifiex/mlanX/:

- [GPIO#]: pin number of GPIO used to wakeup the host.
- GPIO pin# (e.g. 0-7) or 0xff (interface, e.g. SDIO
- will be used instead).
- [gap]: the gap in milliseconds between wakeup signal and
- wakeup event or 0xff for special setting (host
- acknowledge required) when GPIO is used to wakeup host.
-
- Examples:
- echo "-1" > hscfg : Cancel host sleep mode
- echo "3" > hscfg : Broadcast and unicast data;
- Use GPIO and gap set previously
- echo "2 3" > hscfg : Unicast data and GPIO 3;
- Use gap set previously
- echo "2 1 160" > hscfg : Unicast data, GPIO 1 and gap 160 ms
