OTA Generation for Android x86-64

[henry son]

Hello All,

Currently I'm doing OTA update for Android-x86-64, I could successfully done dist build but I got below errors when do OTA generation.
Based on the log I see that the generation is failed since recovery.fstab is not available.

I'm quite doubtful whether Android-x86 support OTA generation or not, I will very much appreciated on your help!

Probably nobody tested it yet.
As the log said, you have to add recovery.fstab.

Hi Huang,

Thanks for your answer, I have added prebuilt recovery.fstab and got some other errors.

Here is my big concern, does Android-x86 support OTA update?

Thank you again!

I've said. Nobody tried it.
However, nobody prevents you from doing it.
You have to work out all the errors.
