Hi,
I just tried the updated Ubuntu Server image and noticed the cpu maximum frequency is 1.488 Ghz when hardware capability is 1.8ghz.
The previous kernel 3.10.65 based images did not have this limitation. I tried hacking the dtb to change it but no difference.
Any ideas and can Sunxi please give an explanation why this is?
Thank you,
Rollmeister
