Android14 OTA添加logo分区升级

下述改动在 vendor 侧完成。
该需求只在项目初期 进行添加， 会改变分区，无法支持跨大版本。

1.修改分区表

AB升级：将AB升级分区表partition_table_emmc_ab.csv内的logo分区一栏删除，然后分别添加上logo_a与logo_b分区，同时将logo_a与logo_b分区的OTA_Update状态由N改为Y；

non-AB升级：将non-AB升级分区表partition_table_emmc.csv内的logo分区一栏的OTA_Update状态由N改为Y；

将partition_table_emmc_ab.csv与partition_table_emmc.csv内的logo.bin修改为logo.img，因为OTA打包时只会打包分区img文件。

• /vendor_ap_s0/vendor/mediatek/proprietary/tools/ptgen/MT6765/partition_table_emmc.csv

  

• /vendor_ap_s0/vendor/mediatek/proprietary/tools/ptgen/MT6765/partition_table_emmc_ab.csv

  

2.修改编译文件

• /vendor_ap_s0/vendor/mediatek/proprietary/bootable/bootloader/lk/Android.mk

     INSTALLED_LK_TARGET := $(PRODUCT_OUT)/lk.img
-    INSTALLED_LOGO_TARGET := $(PRODUCT_OUT)/logo.bin
+    INSTALLED_LOGO_TARGET := $(PRODUCT_OUT)/logo.img

• /vendor_ap_s0/vendor/mediatek/proprietary/bootable/bootloader/lk/build_lk.mk

 BUILT_LK$(LK_MODE)_TARGET := $(TARGET_LK$(LK_MODE)_OUT)/build-$(LK_PROJECT)/lk.img

3.添加权限

如果遇到ota升级失败报下面的错误

E update_engine: [ERROR:utils.cc(530)] Opening block device /dev/block/by-name/logo_b: Permission denied (13)
E update_engine: [ERROR:partition_writer.cc(104)] Unable to open file /dev/block/by-name/logo_b: Permission denied (13)
E update_engine: [ERROR:partition_writer.cc(300)] Unable to open target partition logo on slot B, file /dev/block/by-name/logo_b

按如下添加

• /vendor_ap_s0/device/mediatek/mt6765/ueventd.mt6765.emmc.rc
