Hi. We are seeing a GPU crash during temperature changes and with multiple custom boards with the snapdragon 820c chip. When the snapdragon reads between 9-12 Celsius we will get the below crash. We use /sys/class/thermal/thermal_zone0/temp to read this temperature. Can anyone offer some guidance?
Thanks,
Kim
