Erase, write: OK (flashrom v0.9.3-r1285)
If I erase the chip first (flashrom -E), sometimes a subsequent write operation show an error ("VERIFY FAILED"), but retry and complete (look the attached file). On the other hand, if the chip has something recorded on it, the write operation complete without errors.
In both cases, it works fine.
