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

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

lunch lineage_rpi4-userdebug 找不到 device 參考官方
- 新增AndroidProducts.mk檔案定義COMMON_LUNCH_CHOICES
bootloader 無法載入zImage (linux kernel)
- 修改config.txt不要用位址的方式去定位zImage

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>

修正bluetooth無法正常運作

使用KonstaKANG提供的lieageOS-16.0映像，提取可以用的bluetooth 1.0服務
新增bluetooth 1.0 啟動服務檔案 bluetooth@1.0-service.rpi4.rc

修改manifest.xml 載入bluetooth相關packages

<hal format="hidl">
    <name>android.hardware.bluetooth</name>
    <transport>hwbinder</transport>
    <version>1.0</version>
    <interface>
        <name>IBluetoothHci</name>
        <instance>default</instance>
    </interface>
</hal>

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>
```

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>

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>
