Comment(by charles.herndon@…):

 Replying to [comment:2 hailfinger]:
 > strace is unable to see any flashrom activity because flashrom does not
 use syscalls. (There are no syscalls for flashing.)
 > So if you think flashrom does nothing at all, it is still doing
 something, but no utility like strace can see it.
 > The Winbond chips are really problematic. If we try to program them
 according to their data sheets, they fail sometimes. Any insight is
 appreciated. No other chip vendor has these problems.

 I'm willing to provide any information you need.  The only thing I do know
 about this chip is that by mistake I was successful programming it with an
 EEPROM programmer using the settings for SST49LF004 (I forgot to change
 models to the Winbond part)
