Acidburn thanks! I loved to see the Novaspirit link!!! The guy that made the video told us a lot of settings to take the more from a Raspberry or other PI's devices. I Have a lot to tell you, please stay tuned here because I made a configuration for an OrangePi ZERO PLUS arrived a week ago. I Will try to rebuild the software with the instructions provided by you here and I will recompile the miner!!! Thanks!!! The ZERO PLUS is the littlest 64 bit SBC in the world and it costs only ten dollars. It is quad core only and if I will learn hot to take advantage from the mali GPU I will goal the project: a 12 dollars solarpanel for a SBC OrangePi Zero Plus and I will mine with it for just 25 dollars. The problem is HOW to compile the miner and what should be the most powerfull miner for Cortex CPU and Mali GPU. Many thanks and love from Italy!
