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
