64-bit only Android for i.MX8

Hi,

I was wondering if NXP has all of the drivers, shared objects, and proprietary firmware necessary to support a 64-bit only build of Android on i.MX8?

I tried building a 64-bit only build of Android 9, but this failed due to the lack of 64-bit drivers for some of the VPU and media components. I didn't have enough time to investigate further.

I would like to know if this is possible, as 32-bit software is something we don't need to support and it would be nice to reduce the amount of legacy code in the system to a minimum. This also helps cut the AOSP build time almost in half, and reduces the size of the OTA update packages.

Thanks,
Max

As i kown, we don't have a plan to publish 64-bit drivers for some of the VPU and media components

Ahh, ok. It would be very nice to have a pure 64-bit system for simplicity and security purposes. The only reason we're keeping 32-bit around right now at all is because of the media components.

I found a user guide for 64 bit system

Hi,

This helps with porting software and other existing resources to 64-bit, but doesn't help with the missing 64-bit firmware issue.

Has anyone at NXP attempted to build and run Android using build/make/target/product/core_64_bit_only.mk in ProductConfigCommon.mk?

That would be a good starting point for building a 64-bit clean version.
