Yet another one who got confused by my wording :)
What really happens is that flashrom can not distinguish between the 3
chips mentioned (yet). They all look the same to flashrom and the user
has to help a bit.
I have changed the wording now...
Multiple flash chips were detected: "MX25L1605", "MX25L1605A/MX25L1606E", "MX25L1605D/MX25L1608D"
Please specify which chip to use with the -c <chipname> option.
Multiple flash chip definitions match the detected chip(s): "MX25L1605", "MX25L1605A/MX25L1606E", "MX25L1605D/MX25L1608D"
Please specify which chip definition to use with the -c <chipname> option.
Would that have been less confusing to you?
MX25L1605 is apparently not the correct choice, since that one failed
to erase correctly BTW. It does not matter too much because there are
multiple erase functions defined for each chip and some of them work on
Regarding DualBios: it is of no help for coreboot development (yet),
rather the opposite because the fallback mechanism is not fully
understood yet and makes things more complicated than if it would not
be there to begin with.
But there has been some interest in this and one community member is
working on a coreboot port of a gigabyte board with DualBios which also
led to a new version of a old patch for flashrom that allows to select
the flash chip to act upon.
If you want to help testing, please take a look at this tree on github:
