did you try to program the flash manually, not through the germs but with a simple stand alone program that you write yourself? maybe this can be a help to understand the problem. at the end you can convert that little program to a home-made boot loader.

i use also legacy mode, but not with the altera provided lib. i only use the excalibur.h file to now where the peripherals are. i now it is some more work in the beginning, but it can be faster to detect problems like this.

Tada...and the winner is.....

Something went funny with NIOS2. Ripped out some old code, modified AMD.c file, and wrote some erasing and writing code. NOT WITH THE ALTERA PROVIDED LIB. Guess what? it works.

So GERMS and the LIB are stuffed.

So rewrite GERMS (because I need it) and still figure out why the CS8900 doesn't want to work.

Will keep you updated and will post my code when complete

Now the real question is how many other people in the same situation has got it working?
