How to rebuild a lost CFI table

yes. don't use the flash programmer, but rather the memory test software example (or the like) to ensure that your cfi interface is working, correctly, first. you'll likely run into problems getting this to work. be sure to double check your pinout and the constraints you've placed on the sopc builder cfi peripheral. if all else fails, start using signaltap to debug your design....

oh yeah, and be sure you're not basing your failure on a one board sample. you could just have a bad flash or some sort of board failure.

cheers,

Thanks for the reply. I followed your suggestions, and you&#39;re right - the memory test couldn&#39;t even locate the flash device (I specified all the possible paths I could think of). I&#39;m using different boards in the lab every time, so I don&#39;t think it&#39;s a hardware failure. I also double-checked my top-level entity and pin assignments and I can&#39;t find any glaring errors, then again I might still be missing something. :/
