...Except I never told it to build 'ourboard'; I haven't modified

the target mx6dl_sabresd_config.
But you did indirectly, I have to assume that your default MACHINE is set
for "ourboard"
Correct.
and what's happened here is when the bbappend was added, your
setting of UBOOT_MACHINE_ourboard is an override so it built using that
setting.

You can see this in action by running a bitbake -e (prints the variable
contents and how they were determined).
Umm... Actually, no I dont:
---
$ bitbake -e
[ ...blah, blah, blah...]
# $UBOOT_MACHINE
# set
/home/ewhac/devel/iMX6/fsl-community-bsp/sources/meta-belis3/conf/machine/ourboard.conf:12
# "mx6dl_sabresd_config"
UBOOT_MACHINE="mx6dl_sabresd_config"
[ ... ]
Which is what I expected.
Not what I would expect, if you bbappend was in play correctly, here is
my example:
# $UBOOT_MACHINE [4 operations]
# set /srv/hdd/poky/meta/conf/machine/include/tune-ppce300c3.inc:13
# "bogus"
# finalize ast.py:328 [finalize]
# "was: bogus"
# override[mpc8315e-rdb]:set
/srv/hdd/poky/meta-yocto-bsp/conf/machine/mpc8315e-rdb.conf:11
# "MPC8315ERDB_config"
# finalize override[mpc8315e-rdb]:
# "MPC8315ERDB_config"
# computed:
# "MPC8315ERDB_config"
UBOOT_MACHINE="MPC8315ERDB_config"
And the do_compile / oe_runmake is correct with the mpc...config
Meanwhile, in the build log
tmp/work/..../u-boot-imx/2009.08-r16/temp/run.do_compile.29091:
----
do_compile() {
if [ "" = "ld-is-gold" ] ; then
sed -i 's/$(CROSS_COMPILE)ld/$(CROSS_COMPILE)ld.bfd/g' config.mk
fi
if [ "" = "ld-is-gold" ] ; then
sed -i 's/$(CROSS_COMPILE)ld$/$(CROSS_COMPILE)ld.bfd/g'
config.mk
fi
unset LDFLAGS
unset CFLAGS
unset CPPFLAGS
oe_runmake mx6_ournode_config # <---- ?!?!?!
oe_runmake u-boot.bin
}
----
In the process of reproducing this output, some stuff happened that
makes me think that bitbake's cache is mildly confused. I'll try
scrubbing it and see if things become more consistent. I will also
look into the OVERRIDES mechanism.
Might be a cache issue, but it should recompute the hashes when you add
or remove the .bbappend.
What version of oe-core / bitbake are you working with?
Sound likeyou are trying a clean build, you could just try "bitbake -e
u-boot" without doing a full build and check those two items, the -e
will also give you the do_compile() task.
Sau!
