Hello,

I am reading chapter 2.2.2.1.2 in following Dhrystone data.

Why is cpu_clock setting 10MHz?

In oher Sitara EVM, cpu_clock seeing seems to be 800~1000MHz.

Is it typo?

Hi,

This is a typo. Please see the latest data here: software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Release_Specific_Performance_Guide.html?highlight=cpu%20#linux-performance-guide

Hi Biser,

Thank you for your reply.

I am reading following URL you told.

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Release_Specific_Performance_Guide.html?highlight=cpu%20#linux-performance-guide

But in LM Bench Metrics, cpu_clock (MHz) is also 10MHz.

Could you tell me collect information about Dhrystone at the am574x-idk?

Regards,

Hi Biser

Thank you for your reply.

Sorry,I misread it.

I am reading Dhrystone Benchmark table in RT-kernel Performance Guide.

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Release_Specific_Performance_Guide.html?highlight=cpu%20#rt-kernel-performance-guide

In am574x-idk, cpu_clock (MHz) is also 10MHz.

Could you tell me collect information about Dhrystone at the am574x-idk?

Hi U-SK,

I believe that this an error in the documentation and the AM57x EVM should be running at 1.5GHz as indicated in the earlier section. This will be addressed in the next release. Thanks for finding the problem and posting it here.

Karthik
