Di seguito riporto la sintassi dei comandi da inserire nel file updater-script di un file update.zip utilizzato per flashare gli aggiornamenti su una rom Andorid. Il tutto è stato ripreso da XDA, da qui e qui.
Mounting Partition
MTD
mount("MTD", "system", "/system"); mount("MTD", "userdata", "/data"); mount("MTD", "cache", "/cache"); mount("MTD", "sdcard", "/sdcard");
EMMC
mount("ext4", "EMMC", "/dev/block/mountpoint", "/system"); mount("ext4", "EMMC", "/dev/block/mountpoint", "/data"); mount("ext4", "EMMC", "/dev/block/mountpoint", "/cache"); mount("ext3", "EMMC", "/dev/block/mountpoint", "/system"); mount("ext3", "EMMC", "/dev/block/mountpoint", "/data"); mount("ext3", "EMMC", "/dev/block/mountpoint", "/cache"); mount("ext4", "EMMC", "/dev/block/mmcblk0p23", "/system"); mount("ext4", "EMMC", "/dev/block/mmcblk0p24", "/data"); mount("ext4", "EMMC", "/dev/block/mmcblk0p25", "/cache");
Unmounting Partitions
unmount("/system"); unmount("/data"); OR unmount("/userdata"); unmount("/cache"); unmount("/sdcard");
Format Partitions
format("MTD", "system"); format("MTD", "cache"); format("MTD", "data"); format("MTD", "boot"); format("ext4", "EMMC", "/dev/block/mountpoint"); format("ext3", "EMMC", "/dev/block/mountpoint"); format("ext4", "EMMC", "/dev/block/mmcblk0p23"); format("ext4", "EMMC", "/dev/block/mmcblk0p24"); format("ext4", "EMMC", "/dev/block/mmcblk0p25"); format("ext4", "EMMC", "/dev/block/mmcblk0p22", "/boot");
Copy files from .zip file to phone partition or sd card:
package_extract_dir("Source", "Destination");
Example:
package_extract_dir("system", "/system"); package_extract_dir("data", "/data"); package_extract_dir("sdcard", "/sdcard");
Output a line of text:
ui_print("Text Here");
Delete a file:
delete_recursive("file/path"); delete("/path/to/file");
Run Program
run_program("command", "parameter_1", "parameter_2" [, "parameter_2"[, ... ] ] );
Example:
run_program("/sbin/busybox", "umount", "/sd-ext");
Symbolic Link
symlink("source", "destination")
Example:
symlink("/data/etc/hosts", "/system/etc/hosts")
