Can you elaborate on the above? I have been [I think] successfully using poky+meta-ti
to support internal platform based on DM8148 and DM3730 - meta-ti is the best choice
for a kernel "jumping off point" for these platforms. So far, I've only
had to make a scant few tweaks to get this combo to work, in particular:

* In conf/local.conf, I use this to avoid parsing problems with some meta-ti
recipes (none of which I need at the moment)
# Ignore troublesome TI recipes
BBMASK = ".*/meta-ti/recipes-misc/"

* In distro.conf (I do have my own distro, but it's very close to poky), I needed
# Allow hardware overrides, e.g. armv7a
OVERRIDES .= ":${SOC_FAMILY}"

With these minor additions, I've been able to use the meta-ti layer for [some]
kernel work, u-boot, DSP support, etc - all the stuff one expects the layer
to provide.

I know my setup is a bit outside pure poky+meta-ti, but it does show that
you don't actually have to have Angstrom to use meta-ti.

It would be nice to understand what your concerns are, certainly the details
of your two "Today,..." statements above, if they fall outside what I've outlined
here.
Gary,

Clearly, the README is meant for the new people, who might find it
too complicated for the above fixes to be applied in order for them
to avoid using Angstrom. But you are correct, besides known isues
with gcc-4.6 not working for some components and hence requiring
meta-oe; SOC_FAMILY and systemd dependency in recipes-misc/images
were the only other two things requiring meta-angstrom layer.

You can try the updated meta-ti now, as it should solve those
dependencies, thanks to Koen's latest patches. Please let us know
how it works for you. Thanks.
not sure if you're suggesting i should now be able to build for,
say, beagleboard with the meta-ti layer, but i cloned meta-ti into my
yocto tree, added that layer to bblayers.conf, and tried to

$ bitbake core-image-minimal

and got what i believe gary was referring to above:

$ bitbake core-image-minimal
Pseudo is not present but is required, building this first before the main build
ERROR: ParseError at /home/rpjday/yocto/git/meta-ti/recipes-misc/payload/bonescript.bb:5:
Could not inherit file classes/systemd.bbclass
ERROR: Command execution failed: Exited with 1

or am i misreading what you wrote?
