树莓派4B无线网卡wifi不识别(Centos8)

树莓派4B 2G版本
安装Centos8后不识别wifi网卡

[root@bogon ~]# nmcli d
DEVICE  TYPE      STATE      CONNECTION         
eth0    ethernet  connected  Wired connection 1 
lo      loopback  unmanaged  -- 

经对比能识别的centos7镜像目录

/usr/lib/firmwear/brcm/

找到centos7镜像中文件

brcmfmac43455-sdio.raspberrypi,4-model-b.txt 

资源下载
用工具

将改文件保存至本地
再复制到centos8中
重启
