Android 修改分区大小

这里以android的cache分区为例。

查看当前使用cache大小：

python device/rockchip/common/get_partition_size.py rockdev/Image-tab08_rk66_pas/parameter.txt cache

402653184 Bytes = 383.625365854M 需要32KB对齐

修改：

device/rockchip/common/BoardConfig_tab08_rk66_pas

-  BOARD_CACHEIMAGE_PARTITION_SIZE ?= 402653184
+  BOARD_CACHEIMAGE_PARTITION_SIZE ?= 1610612736   //1.5G

编译验证：

python device/rockchip/common/get_partition_size.py rockdev/Image-tab08_rk66_pas/parameter.txt cache
1610612736

烧写系统后：df -h 查看：

/dev/block/mmcblk2p14 1.4G  108K  1.4G   1% /cache

cache权限：

 ls cache/ -al                                                                                                                                                                           
total 48
drwxrwxrwx  6 system cache   4096 2021-12-31 09:40 .
