Quick question on CONFIG_SYS_CLK_FREQ
For system running with 33MHz is it correct to define it as 33,333,333 or should it be 33,000,000.
You have to use what _realy_ is used on your hardware. So check with your hardware designers, if they soldered a 33.0 MHz oscillator or a 33.333 or...
It shouldnt concern too much, but seeing that something like 33,333,000 is even used, couldnt help wonder what should it really be..
Yes, it should concern. Keep in mind, that a change from 33.0 to 33.3 is 1% and this could result in the system clock running 1% slower (or faster) as desired!
