It is interesting that image built last week can boot at slightly
higher clock of 700MHz Instead of 650 previously. Maybe because it's
getting cooler outside? ;)
Well it still did not overcome 800MHz. I noticed that after stucking
at uhub for about 20 seconds, the console printed the random device
line. Since now I know putty can send break, I tried to break and got
the following result. Seems something got missed and is never waken
up? I wonder what can cause this and is related to CPU/MPC clock. The
clock domains on the AM335x seem to be designed isolated well to be
set independently without affecting others.
