Hi I am using the Altera 1s10 (Stratix) NDK I am using the full_featured reference design as my base and have added an remote_update megafunction. I now have an pin assignment conflict for 3 pins of the sdram address bus. zs_addr_from_the_sdram[1] PIN_W12 zs_addr_from_the_sdram[3] PIN_W10 zs_addr_from_the_sdram[4] PIN_AA11 these pins conflict with the dedicated remote update pins , so i have to move these 3 address pins to other IO pins. but i cannot move to a general purpose IO pin since such a pin would not be wired to the SDRAM in the NDK i tried putting in 3 general purpoese IO pins but i get a verify failed when i download the code. could you please suggest a solution regards pavanLink Copied

Hi ppk031000,
Perhaps it's resulted from the conflicting of external tri-state bus between 2 memory devices on your board. Because I haven't used the board you mentioned, so it's just my speculation.I may give you two suggestions: 1)Perhaps it's because of your carelessness when you created your system, so reopen SOPCBuilder and the SDRAM component wizard.Now check the selection for "Share pins for via Tri-state Bridge" is checked or not, you should *check it* to avoid the bus-sharing result of SDRAM. 2)If the 1) cannot resolve your problem,Go to download or write by yourself a MUX module for your conflicted pins http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wink.gif Regards, Don
