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

[陳柏儒]

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!

 

[c0rnelius]

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

Aren't you using a CM4?

[陳柏儒]

@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

[c0rnelius]

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.

@c0rnelius

OK, I will try cm4 image. Thanks!

@c0rnelius

 

I tried cm4 image. Temperature is come back normal. Thanks.
