Hi there. Im running Centos on a RPi3. I came across a post about how the vidc throttles arm cpu speed to manage voltage drop and heat. So I ran the attached script. I have an official power supply, but still I'm getting the following output: 44.5'C 600/ 600 MHz 0000000000000000000 1.2V 600/ 600/1185 MHz 45.1'C 600/ 600 MHz 0000000000000000000 1.2V 600/ 600/1185 MHz Indicating a measured 1.2v input and 600MHz. What is curious is that none of the flag bits are set. my boot/config.txt contains no clockspeed options. does the CentOS distro come with its own GPU code? The ouptut does not match what I would expect. (I've tried replacing the PSU, with no effect) -- Kv, Kristján Valur Jónsson, RVX -------------- next part -------------- An HTML attachment was scrubbed...
