I guess something is wrong...
Since I have created my own recipes for u-boot/bootstrap and kernel
I have a primary object for the blame ;-) if that is the case.

At least one more has reported u-boot, not beeing installed
and they are not using my recipes.

The machine description contains:
EXTRA_IMAGEDEPENDS += "u-boot"
EXTRA_IMAGEDEPENDS += "at91bootstrap"
This seems to be the way u-boot is used in other boards, correct?

It certainly makes the packages run until do_compile, but not any
further. What do I need to specify to make a package go through
to the do_deploy phase?

at91bootstrap installs its files as part of do_compile
which might be the wrong thing to do.
- It installs though and U-boot doesn't until you bitbake u-boot.

I might make a workaround to install u-boot in do_compile as well.
Part of my u-boot patches contains an new "make DESTDIR=... install
but if there is a preferred way of doing this, I would be keen to know.
U-boot and bootstrap are a bit special, in that they are not part
of the image, you just want to build them and install them anyway.

===============================================


I noted that some boards + 2 packages sets EXTRA_IMAGEDEPENDS.
conf/bitbake.conf:EXTRA_IMAGEDEPENDS = ""
recipes/kexecboot/initramfs-kexecboot-image.bb:EXTRA_IMAGEDEPENDS = ""

They are not using EXTRA_IMAGEDEPENDS += "..."

I assume the first is an initialization, but the second?
Not digged down deep enough to understand if this recipe is used,
but if it is:
Doesn't that mean that any previous declarations/dependencies are gone?


===============================================
I maintain that if I do "MACHINE=at91sam9260dfc bitbake at91bootstrap"
from the build directory, it is ignored and the MACHINE definition
(MACHINE=at91sam9261df) in local.conf is used.

Result:
NOTE: Tasks Summary: Attempted 448 tasks of which 448 didn't need to be
rerun and 0 failed.

If I stay in the same directory and change local.conf
to have MACHINE="at91sam9260dfc" and then do
"bitbake at91bootstrap" then bootstrap builds for the new machine.

I am running OpenSuSE-x64 and this has done things differently
than Ubuntu multiple times...

If you say it should work, and I can't get it to work,
then I will just have to change the local.conf file
(by symlinking) every time I want to build for a new board
