Recently I has done OTA package update in Freescale IMX6
platform and  met some installation problem, maybe it has related much
with code(recovery code).

 

  1. After android receive full OTA package and enter
    into recovery mode, android imx6 can install package correctly and reboot
    normally.
  2. If android receive incremental OTA package and
    enter into recovery mode, some errors happen in package installation, procedure
    is below:

 

  • Android build system generate incremental
    OTA package

./build/tools/releasetools/ota_from_target_files
-v  -i  ~/OTA/update_old.zip  ~/OTA/update_new.zip
  ~/OTA/incremental_update.zip//incremental
OTA package

      (2). Received
incremental  OTA package is saved in /cache

       (3).android system
enter into recovery mode and start to install package.

      (4). Error is below:

  
      ApplyParsedPerms: lsetfilecon of
/system/lost+found to

         u:object_r:system_file:s0
failed: Operation not supported on transport endpoint

  
     set_metadata_recursive: some changes failed
