openvino : what is the reason for this , how to resolve?

Question No:1:

1. https://docs.openvinotoolkit.org/latest/_docs_install_guides_VisionAcceleratorFPGA_Configure_2019R1.html , following this guide, so after step 10 , I get the following errors:

The error that you observed is not related to FPGA. So you should be able move forward with your testing.

Question No 2:

The next step involves flashing with the USB flasher ,

1.Cant we achieve this without the USB flashing ?

You only need to do it the 1st time if you are it is preloaded with the image with the same OpenVINO version.

2.What about Opencl methodology of sending .aocx files to fpga, or any other methodologies.

If you are just want to run different topology then you can use "aocl program ***.aocx" which will update the FPGA topology. If the preloaded image is using different OpenVINO version then you will need to use USB Blaster to flash it before you are able to program it.
