[zhangzhencai]

Dear all,

           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!!!
