also, one time that zImage.chrp was only 570K instead of the expected 1.4M, so netboot failed. But I got no build error.
Any idea what dependency is missing?

That is kinda odd. My thought is that arch/ppc/boot/ just isn't fully safe for -j'ing. Sam, any ideas on how to debug this kinda problem? Thanks.

The problem is that the images/ sub directory is visited before the prerequisites are finished.
I have no good way to debug this - I can see it based on the Makefile and the output Olaf included.

Also the problem Olaf describe is just a cp of a half finished file.

So the fix is to let the images/ directory depends on the rest of the directories.

Something like this may do the trick:

$(obj)/images: $(addprefix $(obj)/,$(subdir-y) $(bootdir-y))

	$(Q)$(MAKE) $(build)=$@

And then delete the assignment of images to subdir-y

Another solution would be to get rid on the images/ drectory and place outputfiles where they are being built.

We had a similar problem with paul recently where the build worked but the resulting zImage contained a corrupted file as the objcopy/gzip/whatever wasn't fully finished when the zImage file got linked.

Something like this may do the trick:

We should maybe also have an explicit dependency on vmlinux no ? Or is this handled already for the boot dir as a whole ?

Hopefully the first works, since I really do like having all the various images we create end up in one spot. :)

This is handled in arch/ppc/MAkefile - so already dealt with.

That still doesnt work right, I touched one .c file which lead to a new vmlinux, now zImage.rs6k is too small:

That still doesnt work right, I touched one .c file which lead to a new vmlinux, now zImage.rs6k is too small:

Is it possible that the dependency is being met by the file being there, but not done? If so, would perhaps depending on System.map as well for vmlinux.bin fix the problem?

This doesn't make sense to me, but taking a quick look over things, zImage.chrp (/etc) do have dependncies on vmlinux.gz which has deps on vmlinux.bin, which deps on vmlinux.
