This is motivated by trying to increase CPU frequency for BeagleBone Black. AM335x cpufreq is not supported yet. In order to achieve the goal to increase CPU freq, I am thinking of a 2-step approach: 1) port latest u-boot, which have cpufreq better organized 2) tweak u-boot opp/freq later With this 2 patches, I can boot into FreeBSD on my BeagleBone Black (BBB), but my BBB consistently reboots every 50 seconds after ubldr boots kernel. It looks like that a watchdog is not cleared, any idea on this?
