1. 在源码目录device/soc/rockchip/rk3568/hardware/wifi下新建目录ap6256

2. 将【ap6256_wifi_蓝牙模块固件】文件夹中的所有文件上传到device/soc/rockchip/rk3568/hardware/wifi/ap6256

3. 修改文件device/soc/rockchip/rk3568/hardware/wifi/BUILD.gn

import("//build/ohos.gni")

AP6XXX_ETC_DIR = "//device/soc/rockchip/rk3568/hardware/wifi/ap6xxx"
AP6256_ETC_DIR = "//device/soc/rockchip/rk3568/hardware/wifi/ap6256" # 新增AP6256固件目录
DNS_CONFIG_DIR = "//device/soc/rockchip/rk3568/hardware/wifi"

ohos_prebuilt_etc("clm_bcm43752a2_ag.blob") {
  source = "$AP6XXX_ETC_DIR/clm_bcm43752a2_ag.blob"
  install_images = [ chipset_base_dir ]
  relative_install_dir = "firmware"
  part_name = "rockchip_products"
  install_enable = true
}

ohos_prebuilt_etc("fw_bcm43752a2_ag_apsta.bin") {
  source = "$AP6XXX_ETC_DIR/fw_bcm43752a2_ag_apsta.bin"
  install_images = [ chipset_base_dir ]
  relative_install_dir = "firmware"
  part_name = "rockchip_products"
  install_enable = true
}

ohos_prebuilt_etc("fw_bcm43752a2_ag.bin") {
  source = "$AP6XXX_ETC_DIR/fw_bcm43752a2_ag.bin"
  install_images = [ chipset_base_dir ]
  relative_install_dir = "firmware"
  part_name = "rockchip_products"
  install_enable = true
}

ohos_prebuilt_etc("nvram_ap6275s.txt") {
  source = "$AP6XXX_ETC_DIR/nvram_ap6275s.txt"
  install_images = [ chipset_base_dir ]
  relative_install_dir = "firmware"
  part_name = "rockchip_products"
  install_enable = true
}

# ======== ap6256 START ========
ohos_prebuilt_etc("fw_bcm43456c5_ag.bin") {
  source = "$AP6256_ETC_DIR/fw_bcm43456c5_ag.bin"
  install_images = [ vendor_base_dir ]
  relative_install_dir = "firmware"
  part_name = "rockchip_products"
  install_enable = true
}

ohos_prebuilt_etc("fw_bcm43456c5_ag_p2p.bin") {
  source = "$AP6256_ETC_DIR/fw_bcm43456c5_ag_p2p.bin"
  install_images = [ vendor_base_dir ]
  relative_install_dir = "firmware"
  part_name = "rockchip_products"
  install_enable = true
}

ohos_prebuilt_etc("fw_bcm43456c5_ag_apsta.bin") {
  source = "$AP6256_ETC_DIR/fw_bcm43456c5_ag_apsta.bin"
  install_images = [ vendor_base_dir ]
  relative_install_dir = "firmware"
  part_name = "rockchip_products"
  install_enable = true
}

ohos_prebuilt_etc("nvram_ap6256.txt") {
  source = "$AP6256_ETC_DIR/nvram_ap6256.txt"
  install_images = [ vendor_base_dir ]
  relative_install_dir = "firmware"
  part_name = "rockchip_products"
  install_enable = true
}

ohos_prebuilt_etc("resolv.conf") {
  source = "$DNS_CONFIG_DIR/etc/resolv.conf"
  install_images = [ "system" ]
  part_name = "rockchip_products"
  install_enable = true
}

group("ap6256") {
  deps = [
    ":fw_bcm43456c5_ag.bin",
    ":fw_bcm43456c5_ag_p2p.bin",
    ":fw_bcm43456c5_ag_apsta.bin",
    ":nvram_ap6256.txt",
    ":resolv.conf",
  ]
}
# ======== ap6256 END ========

group("ap6xxx") {
  deps = [
    ":clm_bcm43752a2_ag.blob",
    ":fw_bcm43752a2_ag.bin",
    ":fw_bcm43752a2_ag_apsta.bin",
    ":nvram_ap6275s.txt",
    ":resolv.conf",
  ]
}

4. 修改文件device/soc/rockchip/rk3568/hardware/BUILD.gn

import("//build/ohos.gni")

if (linux_kernel_version == "linux-6.6") {
  ISP_VERSION_DIR =
      "//device/soc/rockchip/rk3568/hardware/isp-$linux_kernel_version:isp"
} else {
  ISP_VERSION_DIR = "//device/soc/rockchip/rk3568/hardware/isp:isp"
}

group("hardware_group") {
  deps = [
    "//device/soc/rockchip/rk3568/hardware/gpu:mali-bifrost-g52-g7p0-ohos",
    "//device/soc/rockchip/rk3568/hardware/mpp:mpp",
    # "//device/soc/rockchip/rk3568/hardware/wifi:ap6xxx",
    "//device/soc/rockchip/rk3568/hardware/wifi:ap6256",
    ISP_VERSION_DIR,
  ]
}

5. 修改设备树，这里给出补丁

6. 重新编译和烧录，在源码目录下执行命令

   ./build.sh --product-name rk3568 --ccache --gn-args linux_kernel_version="linux-5.10"
