problem of fifo destroy

Hi there,
When I compiled my code and susccessfully generates graph file. But I've met the problem of fifo destroying after I tried to make it work with ncs. The following context is the message I got:

#

E: [ 0] dispatcherEventReceive:247 dispatcherEventReceive() Read failed -1

E: [ 0] eventReader:268 Failed to receive event, the device may have reset

E: [ 0] checkGraphMonitorResponse:922 XLink error
W: [ 0] ncFifoDestroy:2545 myriad NACK

Error - could not close/destroy Graph/NCS device.

#

Thing to be clear is that I tried every USB port on my laptop.Also, my OS is ubuntu16.04, using ncs1 and ncsdk api 2.
Here is my code https://ideone.com/v4CGll
Thanks.

  • Hi @yi-ru
    In order to make sure that your system is recognizing the NCS and that it is able to run properly, can you try running any of the samples that are included in the NCSDK? If hello_ncs_cpp or hello_ncs_py run correctly, then we know that the NCS was able successfully open and close.

    Sincerely,
    Sahira

  • I'm pretty sure that it can successfully open and close, cause I tried others code on the net and it did work.
    So that's the reason I'm confused.
    Thanks.

  • I found out that the problem is the graph file I created can't be destroyed.
    But there isn't much inform about this situation on the net.
    Thanks.

  • Same happens with me as well.
