[flashrom] Re: Tested write confirmation for MX77L25650F

[Anastasia Klimchuk]

Hello Niels,

Thank you for the report!
I also saw when I was reading your first email, it says in the beginning
that you did write successfully - but then a failed address in the logs :)

I think you are right that most likely the meaningful part of the image was
before that failed address, so at the end what was written was working fine.

Maybe you know what was the size of the image, or rather what size of the
meaningful part? Was there a padding at the end to fill in the full size of
the chip? The error gives the first failed address 0x004935c0 which perhaps
was in the padded area already.

Not much to do for this time, it's good that it all works!
For future, it might be useful to turn on verbose mode and then you get a
lot more info in the logs. The options are -V, -VV, -VVV , these are
progressively more verbose with more Vs. Sometimes there can be a
connection error which is outside of flashrom.
