[Error] Quartus not find while ./install_openvino_fpga_dependencies.sh script - Intel® Arria® 10 FPGA (IEI's Mustang-F100-A10)

Finally, I found the problem is that I did not provide enough power to my FPGA board.

Then, the problem is solved by utilizing a external power supplier.

However, the same error message popped up and it is solved by typing sudo updatedb

​

When I followed the instructions in the following link:

https://docs.openvinotoolkit.org/latest/_docs_install_guides_VisionAcceleratorFPGA_Configure_2019R1.html

I am a little bit stuck at the first part of step 14.

1. Could you please tell me why do I need USB Blaster?
2. Aren't the programs in the FPGA board had been already burned into it?
3. Will it affect the DL model which I want to accelerate?

​

Thanks a lot for your help!

​Best,

Charlie
