Hi Tim and all, This is for discussion only. Would you please advice? 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?
