我的配置：
-i.MX6Quad
-内核稳定版本5.5.6
-wifi模块：mwifiex_pcie
-固件：pcieuart8997_combo_v4.bin(来自https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/)
我试图创建一个接入点，但当我启动hostapd时，我总是从固件中得到相同的错误：

有人知道是什么原因造成的吗？如何修复？我搜索了很多主题，但找不到解决这个问题的方法。
感谢您抽出时间
如果有人遇到同样的问题，这里是解决方案：
1( 加载wifi模块
modprobe mwifiex_pcie
2( 设置接口
要使用mwifiex_pcie驱动程序创建访问点，我们需要添加另一个接口：uap0
iw dev mlan0 interface add uap0 type __ap
我们应该有：lo、mlan0和uap0和$ifconfig
3(然后，使用接口uap0 配置接口文件和hostapd.conf
