Grants comment is spot on. eCos is a multi-tasking system. Do we realy
what to stop all other tasks while doing an erase/write
option. Erase's on the EBSA can take a couple of seconds. In my
application i cannot disable interupts for that long. All sorts of
nasty things happen which can take a long time to recover from.
