Because in cars, the temperature will be very high,
when we use IMX8, what do we need to do when the temperature is high?
have to do the frequency down and so on?
No documentation for high temperature protection?
Kindly follow below:
Let me know if you have any queries.
Yes, at higher temperatures you can slow the operating frequency down, stop some of the cores and on-chip peripherals to reduce the power consumption and thermal emission. The current Linux thermal management driver already provides such a feature.
Unfortunately, there is no document for high-temperature protection. It requires a good thermal hardware design along with smart software strategies to balance performance against the heat generated when doing sustained high-performance activities.
For software, all I can say is that our BSP puts in place a bare minimum of Linux power management hooks. Our BSP is in no way tuned for battery operations or to keep the heat down in a high-performance application. The thermal trip points and DVFS settings need to be adjusted for the specific application. Additionally, if active cooling is required, the software would need to be added to control as well as dedicating GPIO pins for the same.
Thank you for your reply .
