Graph is ploting slow in STM32MP1.

[NPal.2]

Processor Name: STM32MP157 Arm®-based dual Cortex®-A7 32 bits + Cortex®-M4 32 bits MPU 

Kernal Version: 5.10.10

linux destro : openst linux

Crankstorybaord Version : 7.1

OpenGLL Version : 2.0

Screen Size : 1024 X 768

I am developing medical GUI application in which i am ploting real time graph with 5 milisecond refresh rate using Crank storyboard.

Graph ploting is taking upto 80 milisecond to draw the graph whereas the redraw time is only 5 miliseconds, and it is also taking 85% of CPU consumption.

when i draw a graph with draw time 140 miliseconds, CPU utilization is decreased to 35-45%.

kindly help me out and give some solution to optimize the redraw time upto 20 miliseconds.

Hi, I am experiencing a similar problem on a STM32MP157C platform.

I wonder if you can share if you found a solution and what was the culprit.
