CPU temperature over 100C on Armbain image. (Bananpi cm4)

陳柏儒 · October 12, 2023

hello,

I found default armbian image will cause the CPU temperature very high.

My cpu freq is setting 1Ghz and usage is around 20%, This should not cause the cpu to overheat.

This is my armbianmonitor -m :

```

Time CPU_cl0/CPU_cl1 load %cpu %sys %usr %nice %io %irq Tcpu C.St.
18:55:22 1000/1000 MHz 0.88 17% 6% 9% 0% 0% 1% 103.0 °C 8/8
18:55:27 1000/1000 MHz 0.89 17% 5% 9% 0% 0% 1% 103.0 °C 8/8
18:55:32 1000/1000 MHz 0.90 17% 5% 9% 0% 0% 1% 103.1 °C 8/8
18:55:37 1000/1000 MHz 0.83 17% 5% 9% 0% 0% 1% 103.2 °C 8/8
18:55:42 1000/1000 MHz 0.76 17% 6% 9% 0% 0% 1% 103.1 °C 8/8
18:55:47 1000/1000 MHz 0.86 17% 5% 9% 0% 0% 1% 103.2 °C 8/8
18:55:52 1000/1000 MHz 0.87 17% 5% 9% 0% 0% 1% 103.0 °C 8/8

```

My cpu's governor is `powersave` and I also see gpu usage, my gpu governor is setting `simple_ondemand`.

I also use bananapi officical image (ubuntu mate) No overheating issues. How can I solve this problem?

Thanks

Providing logs with

armbianmonitor -u

helps with troubleshooting and significantly raises chances that issue gets addressed.

You should not have these overlays enabled; g12a-radxa-zero-gpio-10-led sm1-bananapi-rtl8822cs

hello @c0rnelius

g12a-radxa-zero-gpio-10-led:

It just for testing the gpio function , but not work. I will disable this.

sm1-bananapi-rtl8822cs:

I use this because I want enable wifi function. Did you have any suggestion to enable wifi function ?

Thanks!

Wifi and bluetooth should work out of the box. You also appear to be using the wrong img;

14736 fdtfile=amlogic/meson-g12b-a311d-bananapi-m2s.dtb

Aren't you using a CM4?

陳柏儒 · October 12, 2023

@c0rnelius

I am using cm4 (https://wiki.banana-pi.org/Banana_Pi_BPI-CM4)

My Armbian image download from this page (https://www.armbian.com/bananapi-m2s/) not cm4 page

Because m2s image has the XFCE desktop is good for me.

As far as I understand, these two platforms can share the same image?

Thanks

The answer is, no. This might be the case on the bsp kernel, but not on mainline. Sure they have a lot in common, but by no means is it the same unit.
