Dear All,
Hello. I have questions about thermal protection in BSP L3.14.28_1.0.0.
Some function of thermal protection were implied on L3.14.28_1.0.0.
Ex,
1) Shut down above exceed 105 degrees in thermal_core.c.
2) Reduce the GPU clock exceed 85 degrees in gc_hal_kernel_platform_imx6q14.c.
3) Can't start-up exceed 80 degrees in soc.c of u-boot.
[Q1]
Why is it keeping at this temperature [85C or 80C] about 2), 3)?
[Q2]
Could you tell me the function of thermal protection for the others?
(Ex, Reduce the core clock...)
Best Regards,
Keita Nagashima
Solved! Go to Solution.
Some thermal protection values are hard-coded in low-level software to prevent the SoC damage (for the point 1) or fast overheating to critical level (for the points 2 and 3). The L3.14.28 BSP also includes the OS-level thermal protection driver. Please refer to the Chapter 26 of attached document for more information on it.
Have a great day,
Artur
