Nanopi NEO2 CPU frequency issue

Nanopi NEO2 CPU frequency issue

Hi! I've recently bought a nanopi NEO2 which features an Allwinner H5. On FriendlyArm website (and on Allwinner's too) it is stated that the H5 is clocked 1.5Ghz. I need to perform some heavy job and and noticed that the cpu frequency hits, at full power, only 1Ghz. I checked using cpufreq-info and I got: driver: cpufreq-dt CPUs which run at the same hardware frequency: 0 1 2 3 CPUs which need to have their frequency coordinated by software: 0 1 2 3 maximum transition latency: 244 us. hard
Per request, here are updated instructions for overclocking the NEO2 v1.1 LTS board to 1.3GHz, for the latest builds of Armbian (kernel 4.19+, build 5.70+):   1.  Please note that this will not work on a NEO2 v1.0 board - the first version of the board doesn't include a regulator nor circuit that supports voltage switching.  Only follow these instructions if you are using a v1.1 board!     2.  Edit /boot/armbianEnv.txt, and add these lines: overlay_prefix=sun50i-h5 o
