18 years agoThank you, thank you, thank you, thank you. I have spent the last week frustrated on this problem!
It is now working. Yeah. I am mystified though why the reference documents are incorrect, and also the example files don't have a pin assignment for flash_ce_n. It always seemed weird to me looking through the docs because there was a ce signal for the other chips. Looking at the schematics it is tied to a pull up resistor, so I don't know why I was able to get my verilog code to work without specifying the flash_ce_n pin. I admit though that sometimes that code would work and sometimes it wouldn't, but I don't know why that would be though, seems like it would always be tri-stated. Anyway thanks again for the help, I am going to go study those schematics now..... Simon
