So should this really be 33330000? I have measured the clock frequency on the two Ocotea boards I have on my desk, and both have a clock crystal of 33.3 MHz, not 33.33 MHz. What I don't know is whether the same clock crystal is mounted on all Ocotea boards. Regards, Bart Van Assche. ^ permalink raw reply [flat|nested] 3+ messages in thread

Hmmm. From what I could read from the schematics, it should be 33.33MHz. But here is always a gray zone. I'll ask AMCC, what is equipped right now. Thanks.
