Exception: Status.MYRIADERROR when using fathom ncs and RPI3

idata — Thu, 03 Aug 2017 19:51:17 GMT

Hi,

I am trying to get the stream_infer example running with the older version of the ncs (i.e. the fathom stick) on the RPI3 with raspbian jessie OS.

I followed the getting started guide but when I run stream_infer I get the following output:

_*_Number of categories: 1000

Found stale device, resetting

Device 0 Address: 1.2 - VID/PID 03e7:2150

I was able to run the ncs-check example in the c_examples folder which successfully opened the device. However again when I tried to run the c examples on a network I get the following output:

_OpenDevice 1.2 succeeded

Press q to quit without closing, otherwise just

Graph allocated

GetResult failed, myriad error: This software supports Myriad2 revision C silicon only

Deallocate graph, rc=0

Does this mean that the fathom ncs is not suitable for use with the RPI3?

The Fathom USB stick is intended to be used with SW packages up to Fathom_1.06.

SDK for RPi3 is actually v1.07 and works with NCS stick firmware which is different from that in FathomNCS. So this probably is causing incompatibility that you observe.

Hi georgievm_cms, Would I be able to download the previous version of the SDK(toolkit+api)(v1.06)? I can get v1.06 on fathom.ai/forum, however this sdk does not include the api or any of the python examples.

Hi, actually toolkit+api are released for the first time in v1.07. You can consider Fathom stick as a beta test version of the NCS. They are in fact two different products joined with their appropriate SW. Fathom SW up to 1.06 is intended only for Fathom stick; SDK v1.07 (and future versions) are usable with NCS only and not vice-versa.
