AM69: Example software for measuring power consumption at full load

Hi Fabiana-san,

Thank you for your reply.

Our customer needs a software example to achieve full load condition to measure power consumption at full load.

There are several use cases for the Power Estimation Tool (SPRUJB1), including "Superset" and "100%", which are high-load use cases. Our customer want to know how to achieve these use cases.

How to achieve the use cases on Linux or U-Boot?

Could you provide example codes or scripts to achieve the use cases on the SK-AM69 or J784S4XEVM?

Best regards,

Daisuke

Hi Daisuke,

The assigned engineer is out for the remainder of this work week due to a holiday. Please expect a delay in response.

Thank you,

Fabiana

Hi Keerthy-san,

Thank you for your reply.

The method you suggested for loading CPUs can be found in the following thread for TDA4VM:

e2e.ti.com/.../tda4vm-how-to-get-more-than-90-load-rate-per-core

Can the method for TDA4VM be applied for AM69 and J784S4?

Best regards,

Daisuke

Hi Keerthy-san,

I understand that the "cpuloadgen" tool can control the loads on the eight A72 cores.

How to control the loads on other cores (R5F, C7x DSP) and accelerators (GPU, etc.)?

If so, can the tools run in the background (multiple processes) to simultaneously control the loads on various cores and accelerators?

Best regards,

Daisuke

There are some vision_apps based load generating applications. You can also run some real use cases as well.

Hi Keerthy-san,

Thank you for your reply.

Could you please provide an information about the overview and usage for each of applications in "/opt/vision_apps"?

Best regards,

Daisuke
