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,
