first check if your hardware is ok

if you use the "onchip memory program", try to access the external sram from

either

- "memory view in the debugger", you can write and read to your external

memory from this window,

- access your external sram with some small testcode

(write to sram address and read back)

if your hardware is ok, check the settings in SOPC Builder

"Nios II more CPU Settings"

and system libray properties
