看起来是目录或文件不存在: No such file or directory

晕哥，我目录和文件都对的

那到驱动里面加些代码调试一下?

楼主现在可以了吗？

wupaul2001 · 2020-03-12 12:13:34

问题已找到，是驱动早于rootfs加载，所以驱动不能编译到内核，只能编译为模块，然后加载，否则就会找不到固件

linux 5.X 内核wifi有bug, 请大家注意。具体请看
https://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211.git/commit/?id=91046d6364afde646734c7ead1f649d253c386e9

终于驱动起来了

brcmf: wifi@1 {
reg = <1>;
compatible = "brcm,bcm4329-fmac";

};

最后不要中断，否则会出现超时

也就是说wifi驱动没有bug,设备树配置修改就可以了?

不是，内核，驱动，设备树配置都得改

101. V3s Linux5.2 驱动 AP6181 WIFI模块问题 by @wupaul2001

哪位朋友 AP6212 出现这个错误的？请问怎么解决呢？

拉轰的脚踏车 · 2020-04-11 15:56:30

搞定了 http://cpp.io/blog/viewpost.do?p=4745

linux wifi regulatory database在新版本kernel中的更改
Date: 2018-04-25 12:37
更新linux kernel后经常会遇到这样的错误信息：
“Direct firmware load for regulatory.db failed”
这是因为新版本的kernel更改了load regulatory.db 的方式
解决办法是手动从https://mirrors.edge.kernel.org/pub/software/network/wireless-regdb/ 下载最新的包，解压缩后把regulatory.db regulatory.db.p7s 复制到/lib/firmware即可
然后reboot，看到这样的信息就对了
"cfg80211: Loading compiled-in X.509 certificates for regulatory database"

参考：https://wireless.wiki.kernel.org/en/developers/regulatory/wireless-regdb

但是网卡还是不能正常工作。

原来如此，怪不得一般WIFI驱动都用模块ko形式加载呢。
