    Hi, Anil,

    I've tried this by replacing the current Altera.icd file at /etc/OpenCL/vendors/ with the one at .../19.4/hld/Altera.icd. It is still the same error message during running:Context callback: Malformed program binary: missing .acl.board section

      Hi,
      It turns out that From version 19.4 onwards there are two options available

      1. Legacy emulator

      export CL_CONTEXT_EMULATOR_DEVICE_INTELFPGA=1

      ./host -legacy-emulator

      2. If you want to use the fast emulator

      export CL_CONFIG_CPU_EMULATE_DEVICES=1

      ./host -emulator

      Please try both the options and let us know about the performance.

      Thanks and Regards
      Anil
