While I run the above scripts: sudo ./run.sh -t speedometer
I found Tbench test result will be reported as well, but it reported as a
runtime error.
Tbench test result for ondemand (loops:3)
--------------------------------------------------
Tbench-ondemand avg des perf: -nan
Tbench-ondemand avg freq: -nan
Tbench-ondemand avg load: -nan
Tbench-ondemand total throughput(MB/s): 0
Tbench-ondemand avg throughput(MB/s): 0
Tbench-ondemand total power consumption(J): 0
Tbench-ondemand avg power consumption(J): 0
Runtime error (func=(main), adr=14): Divide by zero
Tbench-ondemand performance per watt(MB/J):
I think we may have more detailed steps to tell every one how to execute the tests easily.
Thanks,
