    Hi Loukas,

    I think the biggest problem you have is that MGD interceptor is only delivered for ARMv7 and ARMv8 platforms the Raspberry Pi 1 is based on the ARM 11 CPU which is an ARMv6 CPU. This is probably why you get an illegal instruction exception the daemon is trying to run V7 instructions on a V6 processor.

    Hope this helps,

    Stephen
