With the latest version you mean code from HEAD (subversion) ?

Why are you using the -c parameter ? Does your board have two flash chips ?

You say you're using the latest version, is this r1256 ?

There is a patch that enables erasing/writing your chip:
http://patchwork.coreboot.org/patch/2456/

Although that patch is initially meant for W39V040FA and W39V040FB, it works
for your chip too, see this message:
http://www.flashrom.org/pipermail/flashrom/2011-January/005723.html

To apply the patch:
1) checkout the source code:
http://www.flashrom.org/Downloads#Installation_from_source
2) run "svn up -r 1247"
3) apply the patch: patch -p0 <
/path/where/you/have/saved/the/patch/enable-unlocking-erasing-writing-W39V040FB-chips.patch
4) run "make"
5) run "./flashrom -Vw bios_new.bin" as root, and don't forget the leading "
./" that runs flashrom from the directory you ran "make" in.
