Hi,

 I tried to use OpenVINO on FPGA. And it will report - "Error Opening AFC resource busy".

I used strace to check system call. I found the error is about /dev/intel-fpga-port.0 is busy. And I'd also found in the previous tried was available and worked but failed in last two tried. So the inference sample code exit. 

Does anybody now how to fix it.?

Hello, Kai-Feng

Could you please try OpenVINO 2018 R 2.0.2 bugfix package l_openvino_toolkit_fpga_p_2018.2.319?

It is available in IRC and includes fix for this issue.

Hi, 

 I'm using OpenVINO 2018.2.30, DLA 1.01 and DCP 1.1. Could I know where to get 2.319?

Hi, 

 I found the issue. The issue is bbs and opae sdk version mismatch. I don't why it happend because it appeared in the same package.

Anyway, i'd already update everything (not openvino) to newest and it worked fine for me now.

I'll test newer openvino later.
