Here are the results for the "SST25LF080(A)" tested with arduino and serprog:
Probe: OK Read: OK Erase: Not OK! Write: Not OK!
I am not sure why, but it seems that all write operations fail. See the attached log for details (the write and erase-log is nearby the same, so i attach only the erase-log).
If i can do (or test) something, let me know.
