Ticket Name: RTOS/TDA2: TDA2x OpenCV Use-case CPU Load

Query Text:
Part Number: TDA2 Other Parts Discussed in Thread: INA226 Tool/software: TI-RTOS Hi, We were trying to run OpenCV use-case vip_single_cam_opencvcanny_sgx_display in Tda2xx_evm_bios with SDK3.1. The CPU load for opencv usecase was 99%. Why is the CPU getting fully loaded? Is there anyway we can solve this? We had also tried running this usecase in Linux, the CPU was fully loaded.

Responses:
Hi, Can you run p and share the output of that. regards, Anuj

Hi Anuj, Please check the performance 'p' log. This is the performance while running the usecase 'OpenCV-Canny edge' on tda2xx evm Bios.
