Error: Unknown device part 10AX115S2F45I1SG

Due to a problem with the FPGA add-on for custom platforms in the Intel® oneAPI software version 2021.2, this error might be seen when compiling an Intel® Arria® 10 FPGA SYCL kernel using the flat flow:

Error: Unknown device part 10AX115S2F45I1SG

A patch is available to fix this problem for the Intel® oneAPI software version 2021.2. Download and install zip/tarball from the following links:

• Patch Intel® oneAPI for Windows
• Patch Intel® oneAPI for Linux

The zip/tarball directory structure should be relative to the FPGA install directory (eg. /opt/intel/oneapi/compiler/2021.2.0/linux/lib/oclfpga). 

1. Set file ownership to root (chown -R root:root).
2. Set file permissions                        

• chmod -R 755                      
• chmod -R g-s

This problem is fixed beginning with the Intel® Quartus® Prime Pro Edition Software version 21.2 and Intel® oneAPI software version 2021.3.
