OTA Android 8.0.0 Update

[vinothkumars]

Hi All,

I have successful built the OTA Android zip file and also update by using same system

Now my intention is to try OTA update by using other OTA android zip file built from other system

What is the difference between two different system OTA Android zip file?

Is there any user guide or document to update OTA  using different system OTA android zip file.

Hi Shivani Patel,

So, we close this one.

Hi, vinothkumar s‌

When doing OTA update built on different machines, one should make sure the Android AOSP (running onboard) build time should be earlier than the OTA package build time.

For example, if your Android AOSP (built on Machine A) build time is Tue Apr 30 11:03:48 IST 2019 and OTA package (built on Machine B) build time is Tue Apr 30 09:03:48 IST 2019 then it will fail.

So, whenever you want to do OTA update, you need to generate the OTA package again.

Kindly generate the OTA package which you trying to upgrade again with below commands and try to update the system with this OTA package:

• make clean
• make -j4 && make otapackage

If the above steps are not working then can you please provide the logs in case of OTA failure.

Hope this will help you.
