Hello there,
Regarding the thermal management in iMX6, I can see that the bootloader (u-boot) does not allow to boot when the on-die temperature is greater than 80C. The macros used in bootloader are:
#define TEMPERATURE_MIN | -40 | |
#define TEMPERATURE_HOT | 80 | |
#define TEMPERATURE_MAX | 125 |
Are these values with respect to commercial iMX6 processors or industrial iMX6 processors?
Thanks,
Jai Ganesh
It is experience value for uboot application layer. If the temp is great than 85C at uboot stage, normally linux could not run.
The value TEMPERATURE_HOT in U-boot is set relatively low for assurance,
in order to avoid overheat issues. Note, the accuracy of the sensor is not high
(~10 degree).
Have a great day,
Yuri
