MCU load calculation

[chetan98]

Hello Nxp team 

I am using Kw45 board using eatt central SDK and I am working with wireless example connecting and printing data in uart I want to calculate MCU load and idle task time and busy time for MCU can NXP share some reference document or way to calculate MCU load.

Thanks and regards

If you are using FreeRTOS: it has built-in performance analysis with information about the CPU load (without the interrupts), see https://mcuoneclipse.com/2018/02/25/performance-and-runtime-analysis-with-freertos/ and https://mcuoneclipse.com/2019/12/31/implementing-freertos-performance-counters-on-arm-cortex-m/ 

Other than that, you could use SystemView: https://mcuoneclipse.com/2015/11/16/segger-systemview-realtime-analysis-and-visualization-for-freert... 

I hope this helps,

Erich
