Here you can post your issues about baikal miners and some help for figured out the Problems some miners have! First i want you to know the orangepi Images on the support page from baikalminer.com figured out the most Problem if the miners dont work! They update the support page asap when Updates come out! The orangepi Image have one 3,9GB and one 8,2GB the 3,9 GB Version have sgminer 5.2.2-b and the 8,2GB Version have sgminer 4.9.4 on it! The 3,9GB Version brings 2 Mhs more!
