    Hi U-SK,

    Dhrystone should typically be a part of the rootfs. Just boot to kernel prompt
    and type dhrystone. You should be able to run dhrystone without any addtional
    installation.

    Latest SDK: http://software-dl.ti.com/processor-sdk-linux/esd/AM57X/latest/index_FDS.html

    Just Install the SDK and boot to Linux prompt on am574-idk. You should be able to run dhrystone
    related experiments.

    Best Regards,
    Keerthy

    Could you tell me possible reasons that makes defference?

    Hi,

    Can you please try withn 1000000000 runs as input? Typically Dhrystone needs bigger runs
    to get you meaninful results.

    Dhrystones per Second:                    8849558.0

    That looks closer to you original post number.

    Hi,

    Just enter command:

    dhrystone


    It Gives output like below:

    "Dhrystone Benchmark, Version 2.1 (Language: C)
    Program compiled without 'register' attribute

    Please give the number of runs through the benchmark: "

    You can enter value 1000000000 & press enter.

    Finally you should see output line like below:

    "Dhrystones per Second:                    8849558.0"

    Hope you can resolve this thread.

    Regards,
    Keerthy
