无法在 Ostro (Yocto) 上使用 WiFi

我刚刚构建了一个 Ostro os 映像并将其烘焙到我拥有的硬件上。但是我无法让 WiFi 工作。

以下是用于调试的命令的输出：

root@intel-corei7-64:~# uname -a

当我跑步时：

connmanctl enable wifi
Error wifi: Method "SetProperty" with signature "sv" on interface "net.connman.Technology" doesn't exist

这里缺少什么？

答案1

根据https://cateee.net/lkddb/web-lkddb/MWIFIEX.html，您必须有 CONFIG_MWIFIEX 才能支持 Marvell Technology Group Ltd. 88W8897 [AVASTAR] 802.11ac 无线。

最有可能的是，您必须重新配置内核才能包含此内容。

编辑：通常默认内核提供选项来检查其配置，如下所示（在目标计算机上）

zcat /proc/config.gz | grep "CONFIG_MWIFIEX"
