Guide to OTA Update in Android for i.MX platforms

[#1]

This document provides steps to perform the system upgrade/OTA update for Android on i.MX platforms.

1. Compile the Android images and generate an OTA Package:
   • source build/envsetup.sh
   • lunch sabresd_6dq-userdebug
   • make -j4
   • make otapackage
2. You can find your OTA package in the below path:
   • ls out/target/product/sabresd_6dq/sabresd_6dq-ota-<xxx>.zip
3. Copy the above OTA zip package to the device in sdcard using adb push
   • adb push out/target/product/sabresd_6dq/sabresd_6dq-ota-<xxx>.zip /sdcard
4. Move the package from sdcard to the location: /cache/update.zip
5. Make the directory and perform the below steps on the device:
   • mkdir -p /cache/recovery
   • touch /cache/recovery/command
   • echo "--update_package=/cache/update.zip" > /cache/recovery/command
   • reboot recovery

The recovery automatically applies the command and installs this update package.

Note: In this document, the setup is for the i.MX6Q SABRESD Board. So, PathName and OTA package name subject to change based on target device compilation.
