  • Hi Shery,

    Could we get a bit more information on your setup?  What compiler are you using? Does the armhf have Neon?  ArmNN needs Neon, and while your armhf may well have it, you may need to make sure that knowledge is passed thru the compiler to your program.

    Can you get any of the simple samples/examples working on your system?

    Cheers,

    Ben
