sdram config

Hi again,

I'm going through some memory configuration issues, with the Altera Stratix II DSP Development Board that Ken and Doug both helped me get the kernel and filesystem working properly on. This board has two of the same sdram modules that the supplied v1.4 example expects for the Nios Stratix II Development board. I had earlier gotten this to work on the DSP board by utilizing just half of the potential memory, in the exact fashion as used in the example version. Now I'd like to modify this to incorporate all of it.

Under the sdram component in the SOPC builder, I'm going about this by modifying the Data Width from 32 Bits to 64 Bits and leaving the rest of the options as is. After generation and compilation, this results in an error from the kernel properties, in the Nios II IDE, for the target board's PTF. It reads, "The currently displayed page contains invalid values." Will the kernel not accept my memory configuration, or is there a workaround for this?

Thanks one more time,

Matt

    I had the same problems. Ken wrote a patch for this issue. Ken, do you still have this patch? If not, I can post it.

    Sounds good to me, if neither of you happen to have that patch on hand might you recall the modifications it made? Is this something I can go through manually?
