the altera niosii dev.board uses the epm7128 as the configuration download device, but microtronix cyclone dev.board has not. so i want to know how the niosii runs the code stored in the flash on microtronix board.[/b]

hello liangyi,

the following is taken from the data sheet of the microtronix cyclone development kit:

<!--quotebegin-microtronix

in addition, when i make a nios2 system(nios2+uart+timer+sdram+flash+opencores 10/100 ethernet mac), it is always warning "cpu: the reset address point to volatile memory. execution of undefined code may occur upon reset.". i don&#39;t know what&#39;s wrong, but i have set the "reset address as flash" and "exception address as sdram".

In my design the Reset Address is pointing to “ext_flash†and Exception Address is pointing to “sdramâ€. The base of ext_flash is 0x0 and is locked. Did you locked the base address?

Bye,
