Problem with underclocking Odroid HC1/HC2/XU4 with Kernel4.19.14/Armbian5.70

Recommended Posts

Hey

 

Can anyone confirm the problem with under-clocking in Odroid HC1/HC2/XU4 with Kernel 4.19.14 / Armbian 5.70?

 

I could always reach 2000/1500Mhz without a problem. Currently, after the last Armbian update from 5.60 to 5.70, I noticed a strange behavior that Odroid does not want to reach full clocks. With cpufrequtils min 600 max 2000 and "performance" and clocks do not want to go higher than 1800/1300Mhz temperature cpu 45.0 ° C.
No changes just last updates nothing more was touched. After returning to 5.60 and 4.14.69 the CPU runs normally at 2000/1500 ....
I also have the impression that HDD sometimes behaves strangely at 5.70 / 4.19.14

 

According to the @tkaiser suggestion....

Most probably device-tree with the new kernel version defines different cpufreq/DVFS operating points and this got undetected (Armbian still supports way too many boards. Quantity vs. quality and one of the usual results).

 

But I agree: should be fixed, so better report your findings where it can be fixed (Armbian and not OMV).

Kernel 4.19.y for Odroid XU4 is not yet well polished. Use stock 4.14.y until then - switch it simple via armbian-config -> system -> alternative kernels and choose latest 4.14.y

Ok.

I did it right away. ;)


I hope that the kernel will be polished in the near future. ;)
