CentosRedhat下bcm43142博通无线网卡linux驱动之二

时间：2022-05-31 03:33:13

上次通过更换内核实现成功编译驱动无线网卡，但是启动到系统原内核下依然没有bcm43142的驱动，遂准备在原内核下编译驱动，记录一下

ps：更推荐这种方法，避免因更换内核出现其他兼容性问题

1.准备驱动包

hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz

点我下载密cmet

下载拷贝进u盘，将源码包拷贝至/usr

2.安装工具

安装gccyum install -y gcc，如已安装可跳过

安装内核对应版本的kernel-headers，kerner-devel，本次使用当前系统镜像作为yum源，所以版本也是一致的

[root@king ~]# yum list|grep kernelkernel.x86_64 3.10.0-327.el7 @anaconda/7.2kernel-devel.x86_64 3.10.0-327.el7 @rhel7.2_iso kernel-headers.x86_64 3.10.0-327.el7 @rhel7.2_iso

3.编译源码与安装驱动

复制源码包并解压

[root@king ~]# mkdir -p /usr/local/other/wireless7_2[root@king ~]# cp /usr/hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz /usr/local/other/wireless7_2[root@king ~]# cd /usr/local/other/wireless7_2[root@king wireless7_2]# tar zxf hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz[root@king wireless7_2]# lshybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz lib Makefile src

编译

[root@king wireless7_2]# makeKBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd`make: *** /lib/modules/3.10.0-327.el7.x86_64/build: No such file or directory. Stop.make: *** [all] Error 2

报错，分析错误原因，发现/lib/modules/3.10.0-327.el7.x86_64/build软链接失效，重做之

ln -s /usr/src/kernels/3.10.0-327.el7.x86_64/ /lib/modules/3.10.0-327.el7.x86_64/build #注意做软链接要写绝对路径

重新编译

发现报错，依次排错

由报错信息知wl_cfg80211_hybrid.c文件第1460，1477，1894，2037，2124行有错，做出如下更改

[root@king wireless7_2]# vim src/wl/sys/wl_cfg80211_hybrid.c1460 // sinfo->filled |= STATION_INFO_TX_BITRATE;1477 // sinfo->filled |= STATION_INFO_SIGNAL;1894 wdev->wiphy->wowlan = &wl_wowlan_support;2035 cbss = cfg80211_inform_bss(wiphy, channel, CFG80211_BSS_FTYPE_UNKNOWN, (const u8 *)(bi->BSSID.octet),2036 0, beacon_proberesp->capab_info, beacon_proberesp->beacon_int,2037 (const u8 *)notify_ie, notify_ielen, signal, GFP_KERNEL);2124cfg80211_ibss_joined(ndev, (u8 *)&wl->bssid, &wl->conf->channel, GFP_KERNEL);

tips：vim里按冒号输入set nu显示行号，冒号后接行号定位到该行

重新编译

没有报错
