banane Posted June 11, 2016 Share Posted June 11, 2016 Hi, on my BananaPI I installed this image: Armbian_5.10_Bananapipro_Debian_jessie_4.5.2_desktop.raw I followed these instructions: https://searchathing.com/?p=250 to move / to SATA (or USB) and crypt it with LUKS. After all, cat /proc/cpuinfo says, there is only 1 CPU-core. How can I activate the 2nd core? Thanks for your help Link to comment Share on other sites More sharing options...

Igor Posted June 12, 2016 Share Posted June 12, 2016 I don't know what you did but there are two cores: - on untouched image - on upgraded to latest kernel (apt-get update && apt-get upgrade) Link to comment Share on other sites More sharing options...
banane Posted June 12, 2016 Author Share Posted June 12, 2016 I followed these instructions: https://searchathing.com/?p=250 to move / to SATA (or USB) and crypt it with LUKS. before I did this 2 cores were available. maybe there is a little mistake, but I don't know, how to solve.
