When I built the rpi3 image, I used the existing rpi2 image we had, including the config.txt that was used. From that wiki page, it seems that we're really under what both the pi2/p3 can support, including default values. Maybe we should at least bump this to "default" values (so not overclocking). So arm_freq set to 900 for pi2 and 1200 for pi3 Opinions ? -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 56BEC54E | twitter: @arrfab -------------- next part -------------- A non-text attachment was scrubbed...
