I'm having a problem with flashrom V0.9.7. I was following instructions that used v0.9.3 to update the bios on a ReadyNAS Pro6, which apparently worked:
# /opt/biosflash/flashrom -c W25x80 -w /opt/biosflash/RN_NV6_072610.ROM flashrom v0.9.3-r1205 on Linux 3.7.5-1.el6.elrepo.x86_64 (x86_64), built with libpci 2.2.4-pre4, GCC 4.1.2 20061115 (prerelease) (Debian 4.1.1-21), little endian flashrom is free software, get the source code at http://www.flashrom.org
Calibrating delay loop... OK. No coreboot table found. Found chipset "Intel ICH8/ICH8R", enabling flash write... OK. This chipset supports the following protocols: FWH,SPI. Found chip "Winbond W25x80" (1024 KB, SPI) at physical address 0xfff00000. Flash image seems to be a legacy BIOS. Disabling checks. Writing flash chip... Erasing flash before programming... Erasing flash chip... SUCCESS. done. Programming flash... done. COMPLETE. Verifying flash... VERIFIED.
But v0.9.7 requires configuration first, which fails, even though it finds both the chipset and the BIOS chip. This is also under a later Debian release, if that matters. The key to the problem seems to be "/dev/mem mmap failed: Resource temporarily unavailable". But I am logged in as root and /dev/mem has the proper permissions:
crw-r----- 1 root kmem 1, 1 Nov 28 23:23 mem
I have verified this response on two identical configurations, but I also have a different model ReadyNAS with the same Debian configuration and it works fine there.
Here is the whole dump of the response:

It might. There were some kernel changes which can impact flashrom's ability to read /dev/mem: https://www.flashrom.org/FAQ#I_get_.27Can.27t_mmap_memory_using_.2Fdev.2Fmem...
Try out the latest sources which (hopefully) don't require you to change kernel options: https://review.coreboot.org/cgit/flashrom.git
