[Yaffs] Fwd: where to get mkyaffs2image tool or source

I'm having issues similar to those already being reported on this list
(unable to open an initial console, and No init found). I'm
suspecting the yaffs2 image I've created is not valid or corrupt or
something. I got the mkfs.yaffs2.x86 from somewhere in China. I'd
like to try the one you all reference here to see if it cures my
problem. Same filesystem mounted via NFS or via JFFS2 seems OK, so my
problem is not missing /dev/console or init. Any ideas?

BTW, what do you mean "Google seems to know a fair bit about this
error message."? I'm actually trying to get android working on my
target, which is why I'm curious.

Thanks,
twebb
