I change my TEMP_CRITICAL by excuting the cmd " cat /sys/class/thermal/thermal_zone0/temp > /sys/class/thermal/thermal_zone0/trip_point_0_temp",then the board is died cant't reboot. There is no response when I press the reset button. Only when i turn off power then turn on the power ,the board start running .
Serial port information:
Chip is too hot, reboot!!!
