[-- Attachment #1 --] Hi, I can't oc the pi in the usual way with -current on rpi4. Obviously I'm doing something wrong, but I don't know what. If I put parameters in config_rpi4.txt, they're seemingly ignored. If I take these out of there and put them instead at the bottom of config.txt, the pi will fail to boot (I think it's failing u-boot, it says, in VGA, it needs newer firmware). I've installed to rpi4 as per https://lists.freebsd.org/pipermail/freebsd-arm/2020-August/022162.html The parameters I want to use are: arm_freq=2100 gpu_freq=750 over_voltage=6 Even with make -j4 it sits stubbornly at 0.6GHz. The cpu is usually below 40 degC in a 20 degC environment. It'll go to 46 degC when make buildkernel runs. I've tried much lower parameters with the same result. What am I doing wrong? thanks, -- J.
