201) FOR DRIVER INSTALL
21
22 a) Copy sd8787.bin to /lib/firmware/mrvl/ directory,
23 create the directory if it doesn't exist.
24 b) Install WLAN driver,
25 insmod mwifiex.ko
26 c) Uninstall WLAN driver,
27 ifconfig mlanX down
28 rmmod mwifiex
29
30
312) FOR DRIVER CONFIGURATION AND INFO
32 The configurations can be done either using the 'iw' user space
33 utility or debugfs.
34
35 a) 'iw' utility commands
36
37 Following are some useful iw commands:-
38
39iw dev mlan0 scan
40
41 This command will trigger a scan.
42 The command will then display the scan table entries
43
44iw dev mlan0 connect -w <SSID> [<freq in MHz>] [<bssid>] [key 0:abcde d:1123456789a]
45 The above command can be used to connect to an AP with a particular SSID.
46 Ap's operating frequency can be specified or even the bssid. If the AP is using
47 WEP encryption, wep keys can be specified in the command.
48 Note: Every time before connecting to an AP scan command (iw dev mlan0 scan) should be used by user.
49
50iw dev mlan0 disconnect
51 This command will be used to disconnect from an AP.
52
53
54iw dev mlan0 ibss join <SSID> <freq in MHz> [fixed-freq] [fixed-bssid] [key 0:abcde]
55 The command will be used to join or create an ibss. Optionally, operating frequency,
56 bssid and the security related parameters can be specified while joining/creating
57 and ibss.
58
59iw dev mlan0 ibss leave
60 The command will be used to leave an ibss network.
61
62iw dev mlan0 link
63 The command will be used to get the connection status. The command will return parameters
64 such as SSID, operating frequency, rx/tx packets, signal strength, tx bitrate.
65
66 Apart from the iw utility all standard configurations using the 'iwconfig' utility are also supported.
67
68 b) Debugfs interface
69
70 The debugfs interface can be used for configurations and for getting
71 some useful information from the driver.
72 The section below explains the configurations that can be
73 done.
74
75 Mount debugfs to /debugfs mount point:
76
77 mkdir /debugfs
78 mount -t debugfs debugfs /debugfs
79
80 The information is provided in /debugfs/mwifiex/mlanX/:
81
82iw reg set <country code>
83 The command will be used to change the regulatory domain.
84
85iw reg get
86 The command will be used to get current regulatory domain.
87
88info
