Measuring clock from DE0-Nano on scope

Hi, I have a clock divider in my design, that takes the 50MHz clock in the DE0-Nano board and divides it so that I get 1MHz in it's output (I can't use a PLL since 50M to 1M is impossible). ...

You need to be a lot more specific about your configuration. What type is the I/O port specified as? Ideally it is a CMOS output without an enable.

Is the clock signal you generate at all influenced by any other signals, such as a reset?

If you send the PLL clock output directly to a I/O pin to you see the correct clock signal?

Is your scope working? Ie, can you probe the 50MHz oscillator on the board and see the correct output?

The more information you can provide in your original question (including code snippets) the better, as followup posts like this aren't necessary.
