SDRAM problem in SOPC builder

Michel,

if you disconnect the SDRAM from instruction master Nios processor cannot execute code from SDRAM.

What's the size of your SDRAM?

--- Quote Start ---

"Warning: cpu: The address range of the slaves connected to the NIOS 2 instruction master exceeds 28 bits. Attempts to call function across 28 bit boundary is not supported by GCC and will result in linker errors"

--- Quote End ---

This warning means if you want use the SDRAM as program memory, the address span should be less then 28 bits.
