一、步驟說明

1. 編譯兩個(gè)新舊版本，需要用到兩個(gè)版本的rk3566_r-target_files-eng.zip文件。

創(chuàng)新互聯(lián)是由多位在大型網(wǎng)絡(luò)公司、廣告設(shè)計(jì)公司的優(yōu)秀設(shè)計(jì)人員和策劃人員組成的一個(gè)具有豐富經(jīng)驗(yàn)的團(tuán)隊(duì)，其中包括網(wǎng)站策劃、網(wǎng)頁美工、網(wǎng)站程序員、網(wǎng)頁設(shè)計(jì)師、平面廣告設(shè)計(jì)師、網(wǎng)絡(luò)營(yíng)銷人員及形象策劃。承接：成都網(wǎng)站建設(shè)、網(wǎng)站建設(shè)、網(wǎng)站改版、網(wǎng)頁設(shè)計(jì)制作、網(wǎng)站建設(shè)與維護(hù)、網(wǎng)絡(luò)推廣、數(shù)據(jù)庫開發(fā),以高性價(jià)比制作企業(yè)網(wǎng)站、行業(yè)門戶平臺(tái)等全方位的服務(wù)。

2. 將兩個(gè)版本的rockdev/Image-rk3566_r/rk3566_r-target_files-eng.zip拷貝到某個(gè)制作空間下，建議文件命名帶上型號(hào)及版本號(hào)，方便維護(hù)，如：

rk3566_r-target_files-XXModel-V3.0.0.zip

rk3566_r-target_files-XXModel-V3.0.1.zip

3. 在源碼目錄下執(zhí)行source和 launch操作。

4. 使用源碼中ota_from_target_files腳本制作差分包：

./build/tools/releasetools/ota_from_target_files -p out/host/linux-x86 -k build/target/product/security/testkey -i version_low.zip version_high.zip ota_version_low_to_version_high.zip

參數(shù)含義：

-p：執(zhí)行腳本所需的依賴庫路徑

-k：指定系統(tǒng)所使用的簽名

注：

1.以上兩個(gè)參數(shù)必須帶上，否則會(huì)報(bào)錯(cuò)；

2.會(huì)依賴 out/host/linux-x86目錄下的相關(guān)資源。

不同平臺(tái)估計(jì)有差異，以實(shí)際為準(zhǔn)。

二、示例

1. 拷貝版本到制作空間

cp /data/version/rk3566_r11/Image-rk3566_r_83372e_1123/rk3566_r-target_files-eng.zip ota_diff_space/rk3566_r-target_XXX_V3.0.0.zip

cp rkcode_sdk11.0_r11/rockdev/Image-rk3566_r/rk3566_r-target_files-eng.zip ota_diff_space/rk3566_r-target_XXX_V3.0.1.zip

2. 進(jìn)到源碼根目錄，先執(zhí)行source和lunch

source build/envsetup.sh

lunch 51

3. 執(zhí)行差分包制作命令：

KVM:/data/workspace/RK_3566_USER_R11/rkcode_sdk11.0_r11$ ./build/tools/releasetools/ota_from_target_files -p out/host/linux-x86 -k build/target/product/security/testkey -i ../ota_diff_space/rk3566_r-target_XXX_V3.0.0.zip ../ota_diff_space/rk3566_r-target_XXX_V3.0.1.zip ../ota_diff_space/rk3566_r_ota_XXX_V3.0.0_to_V3.0.1.zip 2022-12-02 10:12:31 - common.py - WARNING : Failed to read SYSTEM/etc/build.prop 2022-12-02 10:12:31 - common.py - WARNING : Failed to read VENDOR/etc/build.prop 2022-12-02 10:12:31 - common.py - WARNING : Failed to read PRODUCT/etc/build.prop 2022-12-02 10:12:31 - common.py - WARNING : Failed to read SYSTEM_EXT/etc/build.prop 2022-12-02 10:12:31 - common.py - WARNING : Failed to read SYSTEM/etc/build.prop 2022-12-02 10:12:31 - common.py - WARNING : Failed to read VENDOR/etc/build.prop 2022-12-02 10:12:31 - common.py - WARNING : Failed to read PRODUCT/etc/build.prop 2022-12-02 10:12:31 - common.py - WARNING : Failed to read SYSTEM_EXT/etc/build.prop 2022-12-02 10:15:25 - common.py - WARNING : Failed to read SYSTEM/etc/build.prop 2022-12-02 10:15:25 - common.py - WARNING : Failed to read VENDOR/etc/build.prop 2022-12-02 10:15:25 - common.py - WARNING : Failed to read PRODUCT/etc/build.prop 2022-12-02 10:15:25 - common.py - WARNING : Failed to read SYSTEM_EXT/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read SYSTEM/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read VENDOR/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read PRODUCT/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read SYSTEM_EXT/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read SYSTEM/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read VENDOR/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read PRODUCT/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read SYSTEM_EXT/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read SYSTEM/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read VENDOR/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read PRODUCT/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read SYSTEM_EXT/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read SYSTEM/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read VENDOR/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read PRODUCT/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read SYSTEM_EXT/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read SYSTEM/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read VENDOR/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read PRODUCT/etc/build.prop 2022-12-02 10:15:26 - common.py - WARNING : Failed to read SYSTEM_EXT/etc/build.prop 2022-12-02 10:15:43 - ota_from_target_files - WARNING : Duplicate block difference found.

三、錯(cuò)誤記錄

其中-p參數(shù)沒有配置上的話，將會(huì)出現(xiàn)如下錯(cuò)誤：
