After booting up armbian 23.02.2 on my orange pi 4 LTS, cpu temp goes up to 95 deg celcius when stress testing (no heatsink or fan installed at all) and the device reboots shortly afterwards. I ran `armbianmonitor -m` when stress testing and found out that some of the cores are not throttling.
I examined the default trip point settings coming with the image in the file /boot/dtb/rockchip/rk3399-orangepi-4-lts.dtb:
trips {
cpu_alert0 {
temperature = <0x14c08>;
hysteresis = <0x7d0>;
type = "passive";
phandle = <0x5a>;
};
cpu_alert1 {
temperature = <0x17318>;
hysteresis = <0x7d0>;
type = "passive";
phandle = <0x5b>;
};
cpu_crit {
temperature = <0x186a0>;
hysteresis = <0x7d0>;
type = "critical";
phandle = <0xf3>;
};
};
These temperature settings do not match the vendor images' settings, and I changed them to match the vendor images' settings as follows:
trips {
cpu_alert0 {
temperature = <0x11170>;
hysteresis = <0x7d0>;
type = "passive";
phandle = <0x5a>;
};
cpu_alert1 {
temperature = <0x14c08>;
hysteresis = <0x7d0>;
type = "passive";
phandle = <0x5b>;
};
cpu_crit {
temperature = <0x1c138>;
hysteresis = <0x7d0>;
type = "critical";
phandle = <0xf3>;
};
};
After making this change, I no longer have any reboots caused by overheating and `armbianmonitor -m` shows that the cpu is correctly throttled at 85 deg celcius when stressing testing without heatsink or fan.
Is this the right way to solve this issue? If so, can someone make a PR for this? Thanks.
