6. Running FPGA Diagnostics

This section presents instructions on how to run the FPGA diagnostics by using the fpgabist utility. The current AFUs accepted are nlb_mode_3 and dma_afu, running fpgadiag and fpga_dma_test tests, respectively.
Note: If a flash is programmed with a root entry hash, you must ensure that the AFUs are signed with an appropriate root key and code signing key before running the FPGA diagnostics. For more information on signing, refer to Security User Guide: Intel® Programmable Acceleration Card with Intel® Arria® 10 GX FPGA .
  1. Configure the number of system hugepages the FPGA fpgadiag utility requires:
    sudo sh -c "echo 20 > /sys/kernel/mm/hugepages/hugepages-\ 
    2048kB/nr_hugepages"
  2. Configure and run diagnostics with the NLB_3 AFU image.
    sudo fpgabist $OPAE_PLATFORM_ROOT/hw/samples/nlb_mode_3/bin/\
    nlb_mode_3_unsigned.gbs
    Sample partial output:

  3. Configure and run diagnostics with the DMA AFU image.
    sudo fpgabist $OPAE_PLATFORM_ROOT/hw/samples/dma_afu/bin/dma_afu_unsigned.gbs
    Sample partial output:
