那到驱动里面加些代码调试一下?

Re: 请教大家,我编译好AP6181的驱动后,为何死活加载不了固件

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

Re: 请教大家,我编译好AP6181的驱动后,为何死活加载不了固件

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
