標題: 有玩過(guò)wifi模塊的沒(méi)
There are some steps to make the SDIO WIFI module work.
1.configure the kernel
a.select Network stack
Networking  --->
   [*] Networking support
   Wireless  --->
   <*> Improved wireless configuration API
[*] nl80211 new netlink interface support
-*- Wireless extensions
   <*> Generic IEEE 802.11 Networking Stack (mac80211)
   [*] Enable mac80211 mesh networking (pre-802.11s) support
b.select Blackfin SDH driver
Device Drivers  --->
<*> MMC/SD card support  --->
   *** MMC/SD Card Drivers ***
   <*> MMC block device driver
   [*]    Use bounce buffer for simple hosts
   *** MMC/SD Host Controller Drivers ***
<*> Blackfin Secure Digital Host support
[*]    Blackfin EZkit Rev 1.3 Missing SDH_CMD Pull Up Resistor Workaround
c.select libertas driver
Device Drivers  --->
   [*] Network device support  --->
   Wireless LAN  --->
   [*] Wireless LAN (IEEE 802.11)
     Marvell 8xxx Libertas WLAN driver support
        Marvell Libertas 8385 and 8686 SDIO 802.11b/g cards
   [*]    Enable full debugging output in the Libertas module.

2.patch the kernel
cd uclinux-dist/linux-2.6.x
...uclinux-dist/linux-2.6.x$ patch -p0  < sdio_wifi.patch

3.copy firmwares and hotplug script to romfs
cd uclinux-dist
.../uclinux-dist$mkdir romfs/lib/firmware
.../uclinux-dist$cp sd8686.bin romfs/lib/firmware
.../uclinux-dist$cp sd8686_helper.bin romfs/lib/firmware
.../uclinux-dist$cp .../hotplug /romfs/sbin/
.../uclinux-dist$cd /romfs/sbin/;chmod +x hotplug

4.install libertas module
After doing above job,then compile the source and download the image to BF548-EZKIT board
SDIO card should be showed after the image is downloaded to the board.

沒(méi)搞錯吧？你的benq s6山寨的啊/
剛買(mǎi)的還用不了wifi？

作者: wangkj 時(shí)間: 2009-11-11 07:27
是linux用不了，有開(kāi)關(guān)，打不開(kāi)，winxp一切正常。
linux找到了恢復盤(pán)，下不來(lái)，估計gfw吧國外的bt種子封了。
看來(lái)，還得想辦法翻墻。做電工真的很不容易。
