We've tried several iterations with similar results. If we use the FLASH chip in byte mode, we can read fine, but not write/erase (crashes the same). There are two methods to use the SDRAM -- one connects the busses inside nios, one connects the busses outside nios. Both techniques provide the same results as all the other methods. If we just run a simple C application program out of SDRAM, and don't use uClinux, we can rd/wr/erase the flash just fine, in both byte and word mode. If we run a simple assembly code application we can rd/wr/erase the flash just fine. We'll take a closer look at the information you provided -- is there any specific setting we need to make in the kernel configuration that you can think of? Thanks!
