I am using iMX8M Mini EVK and AOSP 9.0 version and I am able to run AOSP successfully on my EVK board.
In my current AOSP version AOSP 9.0 I added some custom code in system service layer, JNI layer, HIDL and HAL layer and it is working fine.
But suppose if in some time new AOSP version released say 10.0 and I want to update my system to this version then how can i do that ?
1. How can I update AOSP version of my device i.e. iMX8M Mini ?
2. Is it possible over OTA ?
3. How can I update over OTA ?
4. And after update do I need to add my changes in AOSP again for my custom code in all the layers ? or
how it will be ?
Please provide some help or suggestion.
