Hi,

You will need to check what the peripheral/memory device at that failed location you have. Most development boards come with reference designs; are you using a reference design provided by the board manufacturer?

Once I found this error, it was caused by a bad SDRAM configuration, memory write cycles seemed to work OK but verification failed.

You will also need to check your NIOS Eclipse project debug configuration.
