How can I fixe Error: AOC: Can't find a valid license for the Altera SDK for OpenCL. I use this DE1-SoC board the BSP support only 14.0 version

Hi

From my understanding, you will need to have a valid Intel Quartus Prime Pro/Standard Edition software license to use SDK for OpenCL. Refer here for Quartus comparison

For license kindly contact your nearest Intel salesperson or distributor to purchase.

To order by phone:
