I was going to report exactly the same problem this morning. We have an
additional problem however. We currently have two Intel Strata Flash
parts in 16 bit mode to form a single 32 bit interface to a StrongARM
SA1110. We have found that sometimes, one chip returns ready, but the
second does not. You are then in a Catch-22 since you're supposed to
re-issue the write command to the one that's not ready but cannot to the
one that is ready.

Has anyone else come across this problem?
