SDK V2 issue using NCS on JOULE

idata · ‎09-25-2018

Hello everyone!

I am currently using sdk v2, and running examples failed. I am using ubuntu 16.04 on Intel Joule.

I was getting the same error earlier, and suddenly it worked once, and started failing again.

I have installed everything based on the scripts given in the sdk. I have also tried installing openCV independently, but the same error persists.

vinay@joule:~/ncsdk-2.05.00.02/examples/apps/hello_ncs_py$ make run

making run
python3 hello_ncs.py;
D: [         0] ncDeviceCreate:307    ncDeviceCreate index 0

D: [         0] ncDeviceCreate:307    ncDeviceCreate index 1

W: [         0] ncDeviceOpen:533    failed to find device

Error - Could not open NCS device.

The device automatically disconnects after the blob gets generated.

Before running the program:

Any leads would be appreciated.

@vinaych

Does it work if connected to USB 2.0 HUB?

Intel Joule USB 3.0 Port -> USB 2.0 HUB -> Neural Compute Stick

@vinaych I also had issues with running the NCS with the Joule. I tried a powered USB 3 hub which didn't work for me. Afterwards I tried using a USB 2 hub which surprisingly worked, but unfortunately this solution did not work for other users. Make sure your firmware and Ubuntu for the Joule is up to date: https://software.intel.com/en-us/flashing-the-bios-on-joule https://software.intel.com/en-us/videos/installing-ubuntu-on-the-intel-joule-compute-module.

Thank you @Tome_at_Intel & @PINTO. Surprisingly it is working with a USB 2 Hub. But it doesn't work with USB 3 hub and also when plugged directly to joule. Not sure why.
