Rainer:

I think your probably running a bit ahead of us.

Keep in mind that at this point meta-texasinstruments has not been 
tested with the poky layer stack.  It is a work in progress and is being 
tested with a layer stack that includes oe-core + meta-oe + meta-angstrom.

It is certainly in scope for meta-ti (new name) to work w/ a stock poky 
release or snapshot, were just not verified that yet.  As of now our 
plan includes building and testing the following layer combinations:

oe-core + meta-ti
oe-core + meta-ti + meta-openembedded + meta-angstrom
poky + meta-ti
oe-core + meta-ti + meta-openembedded + meta-arago <= TI SDKs

[layer names and order not to scale]

We will keep a mirror of meta-ti active at the angstrom URL are using so 
no worries.  We are also working to publish a mirror on yoctoproject.org.

I would encourage you to subscribe to our brand spanking new meta-ti 
mailing list to discuss, monitor and prod.

I don't think any of this explains why you are having proxy issues and 
we will let the rest of the thread play out for that.  I just wanted to 
set your expectations.
