About 64-bit Android on Tegra-X2

Hi,

Now we want to use Tegra-X2 to develop a video device which base on Android.
Does Tegra-X2 support both 32-bit and 64-bit Android N ? Can we select 32-bit or 64-bit Android on Tegra-X2 as we need?

Thanks.

Android is not officially supported, but you will probably find an Android port. I couldn’t answer the 32/64-bit question, but the ARM Cortex-A57 supports both a native 64-bit mode and armhf 32-bit compatibility mode (I wouldn’t expect great performance). Usually the case of whether you can execute both 64-bit and 32-bit is if the 32-bit linker and support of 32-bit libraries are present. In the default case of the L4T which comes with a JTX2 only 64-bit support is natively installed (this isn’t Android); adding foreign architecture of armhf could make that o/s compatible with both 64-bit and 32-bit simultaneously.

Yes, linuxdev is right.
We do not have Andriod BSP support on TX2, but only Linux Driver Package supports development on them, you can find more information from below links:
