How to check power/watt consumption of TDA4VM Evaluation kit during inference(object detection) and normal condition. Is there any software for checking? . Please let me know the procedure/solution for finding the watt consumption

Hi Reebs,

Thank you for your question. Most power consumption estimates for the TDA4VM are conducted using the J721EXSOMXEVM board (which has the same TDA4VM processor) instead of the SK-TDA4VM since the EVM board has current monitors (INA226) which can be used to measure power. SK-TDA4VM does not have these current monitors for lower cost and smaller form factor, so power estimation is unfortunately not supported with the SK board.

For measuring power consumption for TDA4VM, the recommendation would be to use the J721EXSOMXEVM board. We have FAQs on how the EVM can be used to measure power: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1072952/faq-tda4vm-measuring-power-consumption-of-the-device
