Hi Folks!
I have an issue with our custom board using imx8mini EVK as the reference design. The BSP we are using is L4.19.35
During thermal aging test, we check the SOC's temperature every 5 seconds base on the value of /sys/class/thermal/thermal_zone0/temp. The system seems to work as normal condition, the problem occured when the temperature reaches critical point. At the same time, the value from /sys/class/thermal/thermal_zone0/temp reports 90℃ but the system gets shutdown and reports 98℃.
Does anyone have the same problem? Does this consider a normal behavior?
