You are not doing anything wrong. Someone screwed up. I have actually rewritten part of the GERMS monitor. I have lots of legacy stuff out there and actually prefer to use the simple RS232 progamming method for many obvious reasons. I would also have thought that my board was stuffed was it not for the fact that I used an old board with NIOS1. I would program the Flash with NIOS1, reload with NIOS2 and be able to read the data, but not write or erase. It all has to do with the byte, word and double word methods used to write to the Flash (also still have a problem writing to a CS8900 in NIOS2). I took the NIOS1 code and looked how the data was written and then rewrote the code for NIOS2 GERMS. So far it is working. It appears that most or all people are using the Flash Programmer via JTAG and thus have not experienced the problem. Those who do think they are doing something stupid and keeps quiet about it. I am rather busy at the moment but need to use the code myself in the next 2 weeks. If I have time I will post it. victors.
