Why do we want this? We don't do this for any of the boards in
Buildroot, and I'm not sure to see why the apf51 should be different
here.

Surely, if you want to build Buildroot for several boards, you will
create one build tree for each board, and therefore each images
directory will contain only the images for this particular board:

	make O=../apf51 apf51_defconfig
	make O=../apf51

	make O=../apf27 apf27_defconfig
	make O=../apf27

And then in ../apf27/images/, you have images for APF27, and
in ../apf51/images/, you have images for APF51.

Other than that, it looks good.

Thanks!

Thomas

Well, I was going to update all armadeus boards configs with this
mechanism too  :-)

yes but images still all have the same name and we have accustomed our
(non expert) users to recognize their board images with their name
prefix. Our U-Boot update scripts are common to all of our boards and
require the images are prefixed with board name. (For example, our
U-Boot look after /tftpboot/apf27-linux.bin instead of
/tftpboot/apf27/uimage.)

I you don't want us to rename images automatically, I can keep the
instructions in our installation documentation and remove post-image.sh.
Let me know and I will submit a v2 of the patch.

But just one more question: what is the purpose of
BR2_ROOTFS_POST_IMAGE_SCRIPT, if it isn't meant to move/rename images to
fit targeted boards ?

Best regards,
Julien

Since you describe this as a site-specific behaviour, there is no reason
for it to be upstream Buildroot.

You can however add a board/armadeus/README with a little explanations
that all boards will be named the same.

If you really need that script, you can carry it in your local tree, or
even better yet, in your BR2_EXTERNAL tree, and have your own armadeus
deconfigs that reference that script, as:
BR2_ROOTFS_POST_IMAGE_SCRIPT="$(BR2_EXTERNAL)/board/armadeus/post-image.sh"

> But just one more question: what is the purpose of

It is mostly for site-local customisations, that can't really be
upstreamed in Buildroot since they are not generic.

Yann E. MORIN.
