Linux/AM5728: Comparing with TI Bench

Part Number:AM5728

Tool/software: Linux

Hi,

Using AM5728, How can i read DSP Freq(Hz) from a call in my App?

tried to use:

typedef struct Types_FreqHz {
            Bits32 hi;
            Bits32 lo;
        } Types_FreqHz;

"lo" returns 600 but "hi" returns nothing!

my point is to compare my DSP App with TI benchmark.
