Hi Mike,

I do a:
MACHINE=X bitbake my-image
This DEPENDS on a virtual bootloader, which will produce a BOOT.BIN file in
the deploy directory, which is tmp-glibc/deploy.images/X/
If I then do a:
MACHINE=Y bitbake my-image
the BOOT.BIN in tmp-glibc/deploy.images/X/ is suddenly gone!
If i do a
MACHINE=X bitbake my-image
then the the BOOT.BIN in tmp-glibc/deploy.images/Y/ is suddenly gone, and
the one for the X machine appears again. The bootloader recipe is not being
rebuilt at all.
The machines have the same MACHINE_ARCH, they differ on only minor points
(the FPGA).
What is going on here?
I can't be sure, but my guess is the recipe is not marked as being machine-
specific (i.e. PACKAGE_ARCH is not set to "${MACHINE_ARCH}" - is that the
case?) but there is still some variable dependency on a variable that has a
machine-specific value. If it's not obvious from the recipe, check if there are
two sets of tasks for the bootloader recipe in the sstate cache, and then use
bitbake-diffsigs to compare the sigdata/siginfo files.
MACHINE is actually "topic-miami-florida-med-xc7z015" or
"topic-miami-florida-med-xc7z030"
Both machines have MACHINE_ARCH = "topic_miami_florida_med" since they only
differ in the FPGA subsystem, but share all the rest (kernel, bootloader, etc).
Is it forbidden to share $MACHINE_ARCH between $MACHINEs? (And if so, why does
MACHINE_ARCH even exist?)
The BSP layer for the topic-miami machines is here (yes, you can build OE or
Yocto images with it, but I have yet some more work to do to make it a proper
BSP...):
