Re: Questions about Installing SDK

[Stephane Desneux <stephane.desneux@xxxxxxx>]

Hi Walter,

Yes, generally speaking, you should end-up with aarch64 binaries which aren't
specific to your board (this is generally not true for 32 bits arm
architectures, where we see more species...)

That said, it may still depend on what your binaries do :). H3 and M3 are
slightly different and in particular, nothing ensures that kernel configurations
are the same in both AGL builds. So you may still have some glitches, depending
on how "low" your app is poking...

If you stay in upper layers, using AGL APIs and/or high level services, it
*MUST* work because this is the intended goal: build once, deploy on all
platforms with the same SoC architecture.

In extreme cases, you may have to adjust your behavior based on runtime
detection ("am I on M3 or H3???"). For that, the API agl-server-platform-info
[1] will certainly help.

Regarding hardware detection service, you can also watch [2].

I also have something cooking on a hardware detection service and exposure
through agl-service-platform-info here [3], but this is not in AGL yet.
