<DIV>I have three workstations with the same motherboards, all identical (same
revision, chips, etc.). Motherboards have a Winbond W25Q128 flash chip. </DIV>
<DIV> </DIV>
<DIV>I have flashed two of those successfully several times with Buspirate
(internal programmer is a no-go on these boards). </DIV>
<DIV> </DIV>
<DIV>On the third motherboard flashrom fails to identify the flash chip 8 out of
10 times and terminates. Then on the few occasions when it does identify the
flash chip it fails to complete the flashing process successfully (errors
erasing). </DIV>
<DIV> </DIV>
<DIV>I have tried two different Buspirate flashed with firmware 5.1, 6.0, 6.1,
and 6.2 (same results regardless of firmware). All the hardware connections are
fine - I have checked continuity from the flash chip legs to the Pomona clip to
Buspirate. My wire leads from Buspirate to the Pomona clip are short, 10 cm. I
am certain this is not a hardware issue since Buspirate/flashrom work on two
other motherboards.</DIV>
<DIV> </DIV>
<DIV>I just do not know what other test should be pursued to get to a
resolution. I have attached the –V logs for a successful flash from one of
the two boards flashrom works, log where flash chip found but aborts on
errors, log where flash chip not found, and a –VVV log for the latter. I
note that the ‘probing’ results are very different but do not know what that may
lead to conclude.</DIV>

<DIV>Any pointers, comments, help
welcome.</DIV></DIV></DIV></DIV></DIV></DIV></DIV></DIV></DIV></DIV></DIV></DIV></DIV></DIV></DIV></BODY></HTML>
