Thanks for all the help Mark! I can now build and boot
core-image-minimal for the ZCU104 with this:

I spoke to RP briefly. This is no longer a problem is oe-core master:

I think it does point out the "best practice" need to NOT manipulate
'TMPDIR' outside of the local.conf or multiconfig files. In the
multiconfig files I would recommend what we're effectively doing, which
is appending to the version from the local.conf. The end result then
is a reasonable assumption as to the output directories that a
multiconfig will use, so a different config can find and pickup files
from there for inclusion in their configuration.

This looks like it resolves my problem.
It is TCLIBCAPPEND not TCLIBAPPEND and the forcevariable is not needed.
Adding this to my template local.conf now.

Ya, I ran into something similar recently with master.
The TMPDIR's created are as expected, but clearly the path specified in
the default FSBL_FILE isn't expecting the 'glibc' part of it.
Your default value is specified in the zynqmp-zcu102-sdt machine.conf
file:
# First Stage Boot Loader
FSBL_DEPENDS = ""
FSBL_MCDEPENDS = "mc::zynqmp-zcu102-sdt-cortexa53-fsbl:fsbl-
firmware:do_deploy"
FSBL_DEPLOY_DIR = "${TMPDIR}-zynqmp-zcu102-sdt-cortexa53-fsbl/deploy/
images/${MACHINE}"
The problem is we're assuming that TMPDIR is NOT being changed by the
distribution, but it is...
See:
./meta/conf/distro/defaultsetup.conf:TCLIBCAPPEND ?= "-${TCLIBC}"
./meta/conf/distro/defaultsetup.conf:TMPDIR .= "${TCLIBCAPPEND}"
What is expected to happen is the (linux / default) multiconfig says I'm
going to use 'TMPDIR' for all of my stuff....
The Multiconfigs say, I'm going to use: TMPDIR .= "-${BB_CURRENT_MC}"
So if you look at it like:
default:
TMPDIR = "/foo/bar/temp"
mc:
TMPDIR = "${TMPDIR}-${BB_CURRENT_MC}"
you SHOULD end up with:
default = /foo/bar/temp
mc = /foo/bar/temp-zynqmp-zcu102-sdt-cortexa53-fsbl
and magically everything works.. _BUT_ the distro you are using in the
default context is modifying the TMPDIR in some way (see the
defaultsetup stuff above), which is causing things to get out of sync.
This is effectively causing TMPDIR to not be 'stable' so the
distribution ends up changing things.
While purely a workaround, the following SHOULD work (in your
local.conf):
TCLIBAPPEND:forcevariable = ""
(note the :forcevariable may not be required)
Note:
./meta-poky/conf/distro/poky.conf:TCLIBCAPPEND = ""
which is why I'm not seeing this problem when I use poky.
The underlying issue is that each multiconfig is separated and there is
no way to pass information from one context to another, so there is no
way to ask a MC what it's TMPDIR is, so we make assumptions, which in
this case are wrong.
I'm not sure of another way to fix this, or even really identify that
it's an issue. I'm open to any suggestions on how to resolve this.

Please no heckling about the minimal name.
I am trying to build core-image-minimal and fial during image assembly

Note the tmp-glibc-... in the fsbl path.
These are the tmp directories I have,
drwxr-xr-x. 1 balister balister 234 Jan 4 13:22 tmp-glibc
drwxr-xr-x. 1 balister balister 270 Jan 4 13:44 tmp-zynqmp-zcu104-

drwxr-xr-x. 1 balister balister 254 Jan 4 14:00 tmp-zynqmp-zcu104-
sdt-full-microblaze-pmu
It feels to me like the image builder doesn't know to look in quite
the right tmpdir for the fsbl.elf file.
Any how to fix this? Do I have a problem in my setup?
