The first few lines in jedec.c say this:
/* JEDEC Flash Interface.
 * This is an older type of interface for self programming flash. It is 
 * commonly use in older AMD chips and is obsolete compared with CFI.

In other words, don't bother fixing jedec, if it doesn't work.  Try
again with cfi and if that doesn't work either, fix cfi or ask for
help on the list.

Carolyn, this applies to your problem as well.  There have been other
developers working with 64bit flashes, searching the archives you
should find some information or at least some names.


Write programs that do one thing and do it well. Write programs to work
together. Write programs to handle text streams, because that is a
universal interface.
