I have added the coreboot mailing list because I ham not familiar with the board or chipset and I am quite certain someone there knows how to handle this correctly. The new version of flashrom detects that the embedded controller on the board (IMC) accesses the SPI bus concurrently with flashrom. We disable writes for safety reasons in that case (your old version did not...). Apparently there is no way to force writing other than changing the source code (sb600.c). I don't think that is wisely though... Apart from repeating the warning to *NOT* reboot/reset/shutdown the machine (unless you have a known-working external flash programmer), I can not help you further ATM. > -----Original Message----- > From: Stefan Tauner [mailto:stefan.tau...@student.tuwien.ac.at] > Sent: Friday, March 01, 2013 12:09 PM > To: Racine, Michel > Cc: flash...@flashrom.org > Subject: Re: [flashrom] Flashrom erase failure > > On Fri, 1 Mar 2013 17:19:46 +0000 > "Racine, Michel" <michel.rac...@hp.com> wrote: > > > Greetings, > > > > I have an AMD Persimmon dev board.
