We don't have the documents you mentioned. The documentation of our Android BSP could be download from here.

For your reference, there is a porting guide in the Linux BSP web page. You could also read it for porting reference.

Hi @vinothkumars

OTA updates can be:
- full = seamless (system, boot, dtbo,...)
- Incremental – using binary patches applied to data on the device, not whole binaries
