Broadcom的BCM9 4318MPG系列miniPCI网卡，需要在kernel中编译相应的驱动，同时还要使用固件。
|
||
驱动位于kernel中的wireless menu中，固件需要单独下载。注意，firmware是由网卡芯片执行的，所以
|
||
与CPU体系结构无关，只需将其放到目标板的/lib/firmware/b43目录下即可(最后需要运行./ltib --config命令重新生
|
||
成rootfs.ext2.gz.uboot目录)。
|
||
|
||
broadcom的firmware按一下方法安装：
|
||
|
||
wget http://bues.ch/b43/fwcutter/b43-fwcutter-015.tar.bz2
|
||
tar xvf b43-fwcutter-015.tar.bz2
|
||
cd b43-fwcutter-015/
|
||
make
|
||
sudo make install #安装fwcutter工具到host中
|
||
cd ..
|
||
export FIRMWARE_INSTALL_DIR="/lib/firmware"
|
||
wget http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2
|
||
tar xvf broadcom-wl-5.100.138.tar.bz2
|
||
sudo b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" broadcom-wl-5.100.138/linux/wl_apsta.o
|
||
ls /lib/firmware/b43/
|
||
sudo chmod -R 755 /lib/firmware/b43/
|
||
ls /lib/firmware/b43/
|
||
sudo mkdir -p ~/PPC/ltib-mpc8315erdb-20100719/rootfs/lib/firmware/b43
|
||
sudo cp /lib/firmware/b43/{bog*,ucode5.fw} [[~/PPC/ltib-mpc8315erdb-20100719/rootfs/lib/firmware/b43]]
