Am I reading what I am- that you are erasing a sector by writing 0xFF to
all the locations in the flash as your code does not support the sector (or
flash) erase command?
You cannot do this. Flash is NOT RAM. The only way to change a '0' bit to a
'1' bit in _ANY_ location is by erasing the entire sector where the
You may change a '1' bit to a '0' bit in any word in the flash by writing
an appropriate word to that location with a '0' in that bit location.

Well, what did you expect to see? I've noticed in the past that if I issue
of pair of SIGSTOP/SIGCONT's to the GC task I can reliably wake it up- but
if there are not many things to erase on the device, the gc task will print
out a bunch of stuff on the console (if level 1 is enabled) complaining
that it was woken up but : "where have all the erase blocks gone"?
