While capturing greyscale images, we can meassure a temperature value around 35.0 to 42.0 °C. The values changes a little, but are continous. When doing some calculations on the image and producing a high cpu load >80%, the tmu values start floating between 25.0 to 120.0 °C.
PID PPID USER STAT VSZ %VSZ %CPU COMMAND
227 224 root S 132m 145% 83% ./myApp
I can confirm, that the tmu-driver works correct, cause this does not happen in idle meassurement.
Can you reproduce these behaviour?
