Dear Stefan, The CPU and bus related info is hard-coded in the code. This is what I saw from my code. Not very sure of it, though. Yes, could be that you are using the fixed, compiled-in speed configuration. This arises another question. Assume that both configurations (CP

Hi there, We've got a board powered by 405ep running at 266MHz. Now we want to upgrade the clock rate to 333MHz (model: 3LB333C), can anyone give us some pointers doing this? I've tried to search the mailing list but found nothing quite related. Also there seems to exist very limited ports, if not
