[meta-ti] Building Yocto for Pandaboard

[Robert P. J. Day]

  i'd like to try to reproduce what's below, so a few questions first.
is this for a regular panda, or a 4460-based panda ES?  i'm
specifically interested in the ES, but there's a good chance a regular
build will still at least boot and i'll worry about any weirdness
later.  and i don't see anything in the meta-ti layer yet
*specifically* for the 4460.

  FYI, my setup is 64-bit ubuntu 11.10 with fully pulled

  * yocto
  * meta-ti
  * meta-openembedded (with underlying meta-oe layer, of course)

  and now, the stupid questions ...

  i remember that issue and, rather than remove systemd, i followed
someone else's suggestion and just added the meta-oe layer to pull it
in.  here's my layers info, does it look sane?  (is that the correct
order to get the right precedence?)

BBLAYERS ?= " \
  /home/rpjday/yocto/git/meta \
  /home/rpjday/yocto/git/meta-yocto \
  /home/rpjday/yocto/git/meta-openembedded/meta-oe \
  /home/rpjday/yocto/git/meta-ti \
  "

if systemd is truly a problem, i can take it out.

i noticed that already, that's what i'll be using as well.

  and you did that how?

  based on what i read here:

http://www.mail-archive.com/openembedded-devel@lists.openembedded.org/msg24283.html

can i just add that line

GCCVERSION = "4.7%"

to my local.conf?  might as well jump up to gcc 4.7.

  and i currently get a fetch error for udev 173, so i set the
PREFERRED_VERSION to 181.  did you not get such an error?  more later.
