Your hostname in the past tells me that you use Debian. Although I don't
(won't) use this myself, the dependencies should be the same as Trisquel.
You should probably recompile it.
So install these dependencies (as per the readme):
sudo apt-get -y install libpci-dev pciutils zlib1g-dev libftdi-dev
(libftdi is needed, this command will install it. The output says that you
don't have it)
And then:
make clean
make
Then try again:
sudo ./flashrom -p internal -w coreboot.rom
If it says "VERIFIED" at the end, then it worked!
At that point, shut down then wait a few secs, and turn it back on.
If it doesn't say VERIFIED, then it would have complained about multiple
flash chips. In that case, do this instead:
sudo ./flashrom -p internal -w coreboot.rom -c "MX25L1605D/MX25L1608D"
------------
Note,
you can also install flashrom from the repository.
sudo apt-get install flashrom
Then do instead, like so:
sudo flashrom -p internal -w coreboot.rom
or (if the above doesn't work):
sudo flashrom -p internal -w coreboot.rom -c "MX25L1605D/MX25L1608D"
