For you or any one else listing I should mention that TI SDKs today are 
still based on oe classic.  The layers we use for these are always 
publicly available at http://arago-project.org

If you need something that has been tested by TI today, you may want to 
look there.  If your willing to work through a few bumps and want to 
start on the new baseline then we would be happy to work with you on 
poky/oe-core + meta-ti.

We expect meta-ti to have some boards tested to the above layer stacks 
in November and most/all boards working by the end of the year.  The 
first TI SDKs built from the new structure will be in Q1 2012.

Humm,  I need to be careful or I may sound like I know what I am doing. 
  However, a quick look[1] makes me think that AM8148 should be using 
u-boot_2010.06-psp.

There are few things that could be going wrong.  Why don't you move this 
thread to meta-ti and Denys and Koen should be able to help you.
