Viewing SDRAM on Development Kit from NIOS II IDE

how about a pll for the sdram?

so, i presume that, you have a program running that change/modify/update the sdram, then the program stopped, and you download the dummy program (or hello world as quoted) to monitor the memory in the nios ii ide?

or is it a multiprocessor, so you have the intended program running on cpu_1, and have the dummy program (hello world) running on cpu_2?

You were correct with the first guess. There is a system running that modifies some of the SDRAM contents and I wanted an independant way of verifying the data that was stored in those locations. However, upon thinking about it further, I would think I should be able to set a logical breakpoint in my current application code, and use the Nios II IDE Memory view capability to view the SDRAM contents. Have you used this capability of Nios II IDE when running under Debug mode?

Also, I believe SOPC Builder automatically generates a clock for the SDRAM controller component from the same PLL that is used to generate the Nios II system clock.

Thanks for your input.

Brad.
