Turn off the Linux temperature limit LS1046A

hyeonbin — Wed, 28 Feb 2024 06:08:56 GMT

I'm building and using a board based on LS1046A FRWY and using Linux to run the system.
CPU for temperature specifications
I'm using LS1046AXN8T1A product with -40°C to 105°C, but the system automatically stops when the temperature exceeds 85°C on the software.
Is there a way to unlock or modify this temperature limit?

I've been looking up Google and dtsi, but I can't find the right answer.

Please refer to the documentation located at: https://www.nxp.com/docs/en/user-guide/LSDKUG_Rev21.08.pdf
Specifically, navigate to Chapter 11.3 Thermal Management User Manual.
Additionally, for reference, the location of the dtsi file is:
vim ./arch/arm64/boot/dts/freescale/fsl-ls1046a.dtsi
A key words to look for is "thermal-zones".
This information should assist you.
