Works fine here, but having a commandline option such as the "content=..." in the updated patch is worthwhile IMHO, it saves the user quite some unneeded hassle to create dummy images on a filesystem, which is possibly even a bit harder on DOS or elsewhere due to missing dd and so on. Also in the qflashrom GUI I'd personally like to be able to present the user with a drop-down of possible dummy chip contents (which are autogenerated by libflashrom). The "image=" option should stay of course, it's very useful too, e.g. for specially crafted test images etc. But for a few simple cases such as 0x00, 0xff, random, etc. the "content=" option makes sense, IMHO. > did i mention that the man page needs an update? :P That too, yes.
