TDA3XEVM: How to check DSP1 frequency?

Shine

Part Number: TDA3XEVM

Hello Champs,

Customer ran below red-highlighted demo in PROCESSOR_SDK_RADAR_03_08_00_00. It only printed IPU frequency. He wanted to know how to print/view the DSP1 frequency.

Thanks.

The boot log at the beginning shows the DSP frequency.

When running the use case, it is showing CPU utilization.

The first use case doesn't utilize DSP.

Just try any of the use case which utilizes DSP and it will display CPU utilization on DSP.

Hi Stanley,

Thanks for your great support.

Customer found the DSP1 frequency in boot log, it shows the cpu frequency is 354MHz, but the datasheet shows that it can reach 745MHz. So how to change the DSP1 frequence?

Thanks

If you check the sbl binaries folder, there should be 3 different OPPs, opp_high, opp_nom, and opp_od.

The opp_high version should set DSP at 745Mhz.
