Host-AP 功能准备

---

下载需要的文件 在网盘 “MYZR-IMX6 > 5_MY-Demo” 中下载以下文件：

• 驱动模块和内核
  

　　my-demo-8188eus-l4115- .tar.xz

• Host-AP 程序
  

　　my-hostapd-2.6-l4115- .tar.bz2

• 配置文件
  

　　my_wlan0_hostap_conf_ .tar.xz 把下载的文件复制到开发板上 这个步骤自己采取U盘、SD卡或自己熟悉的其它方式完成。 解压文件

• 解压驱动模块和内核
  

# tar xf my-demo-8188eus-l4115- .tar.xz -C ~

• 解压 Host-AP 程序
  

# tar xf my-hostapd-2.6-l4115- .tar.bz2 -C /

• 解压配置文件
  

# tar xf my_wlan0_hostap_conf_ .tar.xz -C / 为系统运行准备

• MY-IMX6-EK200、EK314、EK336 上替换内核
  

# mount /dev/mmcblk3p1 /mnt/# cp ~/my-demo/zImage-myimx6a9-l4115-svn241 /mnt/zImage-myimx6a9

• MY-IMX6-EK140P 上替换内核
  

# mount /dev/mmcblk1p1 /mnt/# cp ~/my-demo/zImage-myimx6a7-l4115-svn241 /mnt/zImage-myimx6a7

• 为 DHCP 创建文件
  

# touch /var/lib/misc/udhcpd.leases

• 写入存储并重启设备
  

# sync && reboot
