Reset Address points to volatile memory

Hello Folks,

In SOPC builder I have a warning which says "Reset address points to volatile memory; undefined execution of code may occur upon reset".

This refers to the SDRAM I added. I wanted to know if this can cause a problem in my design or I should simply ignore it.

Thanks.

    I get this warning in my designs also. I think it can be ignored as when the Nios II IDE runs it loads a program into SDRAM and then runs from there. I think the warning is simply to state that if the SDRAM has not been loaded with a program when the CPU starts execution at the start address in the SDRAM there will be no valid instructions to execute.
