Hello, 

 

I use the Microtronix Cyclone1c20 board(the first version). The flash on the board is AM29DL323D and Mtx give a SOPC component of the flash. But when I add it to the system and set the reset address to the Mtx flash module, it always occur warning. 

 

Warning: "The reset address points to the volatile memory. Execution of undefined code may occur upon reset". 

 

But I replace it by the common flash interface, no warning appear. Is there a bug of Mtx flash module. Once I used it in SOPC builder 2.7, it is OK. But in SOPC builder 4.1 with Nios2, it has warnning. 

 

By the way, if I use the common flash interface instead, how to set the proper Setup/Wait/Hold time of the AM29DL323D flash. 

 

Thank you.
