一.先拿到驱动源码

   获取源：咨询模组厂商，让他们提供即可

   比如我这里获取到的驱动源码包名称是：ZTOP_ACEV100_Android_wifi_bt_20260326214112.tar.gz

   解压后的目录截图如下：

需要确认的项：

    确认项目上使用的内核版本是：linux 5.10

    确认mp_hi3781v735时arm32还是arm64: arm64

二.编译

1.源码应该放在哪里？

     这里的OH 6.1 release的项目根目录是在 hisi73561_0410

   直接放在项目跟目录下面：

2.如何让驱动源码参与编译

1.修改如下配置：

2.编译：

变量指令： sudo ./build_linux.sh mp_hi3781v735

三.如何加载wifi驱动的ko

1.编译生成的ko：ZTOP_ACEV100_Android_wifi_bt_20260326214112\wifi_driver\build\output\ztop_wifi_driver.ko

2.厂商随驱动提供的固件：ZTOP_ACEV100_Android_wifi_bt_20260326214112\wifi_driver\fw\zt9612_fw.bin

3.打包文件到镜像中:

将上诉两个文件(ztop_wifi_driver.ko合zt9612_fw.bin)拷贝到项目目录vendor目录下：

比如此处的：vendor\hisilicon\mp_hi3781v735

新建一个目录wifi_ztop

vendor\hisilicon\mp_hi3781v735\wifi_ztop\BUILD.gn的内容如下：

  install_images = [ chipset_base_dir ]
  relative_install_dir = "../etc/ko"
}

# 后续wifi固件都应存放在/vendor/firmware目录
ohos_prebuilt_etc("zt9612_fw") {
  source = "zt9612_fw.bin"
  part_name = "product_mp_hi3781v735"
  subsystem_name = "product_mp_hi3781v735"
  install_enable = true
  install_images = [ chipset_base_dir ]
  relative_install_dir = "../firmware"
}

# 汇总所有依赖
group("ztop_wifi_drivers") {
  deps = [
    ":rwnx_karst",
    ":ztop_wifi_driver",
    ":zt9612_fw",
  ]
}

4.加载ko

四.编译镜像上板验证

1.静态验证，看是否ko和bin都被打包到了正确的目录下面：

2.手动insmod /vendor/etc/ko/ztop_wifi_drvier.ko看是否生成了wlan0接口

查看命令：ifconfig -a

有wlan0说明wifi驱动加载成功！

五.打开wifi流程失败问题解决

问题现象：
