PROCESSOR-SDK-AM62X: Android AOSP - RAM Utilization Problem

Part Number: PROCESSOR-SDK-AM62X


Hi,

I would want to deploy android application on am62x.

However it took 1.6GB RAM memory without launching my application after booting am62x up and it was only 300MB free RAM available.

And I read Android Compatibility Definition Document and It described that android12 RAM requirement for Automotive device.

If Automotive device implementations are 64-bit:

  • [7.6.1/A-2-2] The memory available to the kernel and userspace MUST be at least 944MB if any of the following densities are used:

    • xhdpi or higher on small/normal screens
    • hdpi or higher on large screens
    • mdpi or higher on extra large screens

https://source.android.com/compatibility/12/android-12-cdd#2_device_types

How much RAM is needed to be reserved, from your experience, to keep a favorable user experience after running the OS and apps in the background?

Regards,

Ken

    Hi,

    board have 2Gb , it's a eval board so RAM size is limited for a better experience probably have 3 or 4 GB for RAM could be better for your final board but it's really depending of your application and your display resolution and screen density potentially some other features enabled or not.

    Actually a lot of application already works without any issue so you could probably do some test on AM62 SK board and see if your app have some issue(performance or crash or other).

    Second point actually android have only tablet variant and not automotive variant, it's planned to have automotive variant in few months. So result and memory free could be not the same as actually.
