LineageOS 16.0 device configuration for Raspberry Pi 4.

說明

這是LineageOS 16.0 使用 Raspberry Pi 4 的編譯設定環境，相關說明和操作參考

不用master branch 了

操作說明文件

  • 如何下載LineageOS程式碼

    • 執行腳本輸入提示
      • branch: lineage-16.0
      • device name: rpi4
    #自動化下載腳本
$ wget https://raw.githubusercontent.com/02047788a/build-lineageOS-rpi3/master/scripts/sync-lineageos-code.sh -O sync-lineageos-code.sh
# 執行腳本輸入提示
# Please entry lineageOS checkout folder : /home/Downlaods/LineageOS-16.0  (your source folder)
# Please entry checkout lineageOS branch : lineage-16.0 
# Please entry build device name(ex:,rpi3,rpi4) : rpi4

    輸入的變數都存在~/.profile 裡面 ($LINEAGE_SRC, $LINEAGE_BRANCH, $DEVICE_NAME)

  • 如何編譯LineageOS程式碼

    # 下載腳本到程式碼目錄
$ wget https://raw.githubusercontent.com/02047788a/build-lineageOS-rpi3/master/scripts/build-lineageos-code.sh -O build-lineageos-code.sh
$ sudo ./build-lineageos-code.sh #編譯全部映像kernel ramdisk systemimage vendorimage

    編譯後產生可安裝的image路徑: $LINEAGE_SRC/out/target/product/rpi4/lineage-16.0-20200201-rpi4.img*

  • 燒錄映像到SD卡

    $ sudo dd if=lineage-16.0-20200201-rpi4.img of=/dev/sdX status=progress bs=4M

    /dev/sdX 是你SD卡的路徑，注意要改阿!!!

修正問題

  1. lunch lineage_rpi4-userdebug 找不到 device 參考官方
  2. bootloader 無法載入zImage (linux kernel)
    • 修改config.txt不要用位址的方式去定位zImage
  3. 修正wifi無法正常運作
    • 修改rpi4.mk 編譯時指定wifi需要用到的packages 
      # WIFI
PRODUCT_PACKAGES += \
 android.hardware.wifi@1.0-service \
 hostapd \
 wpa_supplicant
    • 修改init.rpi4.rc 啟動wpa_supplicant 參數 
      service wpa_supplicant /vendor/bin/hw/wpa_supplicant \
    -O/data/vendor/wifi/wpa/sockets \
    -g@android:wpa_wlan0
    interface android.hardware.wifi.supplicant@1.0::ISupplicant default
    interface android.hardware.wifi.supplicant@1.1::ISupplicant default
    class main
    socket wpa_wlan0 dgram 660 wifi wifi
    disabled
    oneshot
    • 修改manifest.xml 載入wifi相關packages 
      <hal format="hidl">
        <name>android.hardware.wifi</name>
        <transport>hwbinder</transport>
        <version>1.2</version>
        <interface>
            <name>IWifi</name>
            <instance>default</instance>
        </interface>
    </hal>
    <hal format="hidl">
        <name>android.hardware.wifi.hostapd</name>
        <transport>hwbinder</transport>
        <version>1.0</version>
        <interface>
            <name>IHostapd</name>
            <instance>default</instance>
        </interface>
    </hal>
    <hal format="hidl">
        <name>android.hardware.wifi.supplicant</name>
        <transport>hwbinder</transport>
        <version>1.1</version>
        <interface>
            <name>ISupplicant</name>
            <instance>default</instance>
        </interface>
    </hal>
  4. 修正bluetooth無法正常運作 
        <hal format="hidl">
        <name>android.hardware.bluetooth</name>
        <transport>hwbinder</transport>
        <version>1.0</version>
        <interface>
            <name>IBluetoothHci</name>
            <instance>default</instance>
        </interface>
    </hal>
  5. 修正health服務無法正常啟動 (無法正常進入Android)
    • 使用KonstaKANG提供的lieageOS-16.0映像，提取可以用的health 2.0服務
    • 新增health 2.0啟動服務檔案 health@2.0-service.rpi4.rc
    • 修改manifest.xml 載入health相關packages 
      <hal format="hidl">
    <name>android.hardware.health</name>
    <transport>hwbinder</transport>
    <version>2.0</version>
    <interface>
        <name>IHealth</name>
        <instance>default</instance>
    </interface>
</hal>
  6. 修正DRM服務無法正常啟動
    • 修改rpi4.mk 編譯時指定wifi需要用到的packages 
      # DRM
PRODUCT_PACKAGES += \
android.hardware.drm@1.0-impl \
android.hardware.drm@1.0-service
    • 修改manifest.xml 載入health相關packages 
      <hal format="hidl">
    <name>android.hardware.drm</name>
    <transport>hwbinder</transport>
    <version>1.0</version>
    <interface>
        <name>ICryptoFactory</name>
        <instance>widevine</instance>
        <instance>default</instance>
    </interface>
    <interface>
        <name>IDrmFactory</name>
        <instance>widevine</instance>
        <instance>default</instance>
    </interface>
</hal>
  7. 修正configstore服務無法正常啟動
    • 修改rpi4.mk 編譯時指定wifi需要用到的packages 
      # configstore
PRODUCT_PACKAGES += \
    android.hardware.configstore@1.1-service
    • 修改manifest.xml 載入health相關packages 
      <hal format="hidl">
    <name>android.hardware.configstore</name>
    <transport>hwbinder</transport>
    <version>1.1</version>
    <interface>
        <name>ISurfaceFlingerConfigs</name>
        <instance>default</instance>
    </interface>
</hal>

已知問題

  1. 重開機後Apps Icon會不見
  2. 無法adb連線
