Hello @Lexus

你需要修改Wi-Fi 驱动，打上如下patch：

重编内核或者固件，系统起来后在配置文件/lib/firmware/brcm/config_bcm43752a2_pcie_ag.txt中添加MAC地址mac=xx:xx:xx:xx:xx:xx例如：

root@Khadas:~# cat /lib/firmware/brcm/config_bcm43752a2_pcie_ag.txt
wl_preinit=pm2_sleep_ret=2000
mac=d4:9c:dd:f6:42:66

保存文件重启，Wi-Fi将会使用配置文件里面定义的MAC地址。

root@Khadas:~# ifconfig wlan0 | grep ether
        ether d4:9c:dd:f6:42:66  txqueuelen 1000  (Ethernet)
