Yeah, SRC_URI already contains "defconfig" entry, thus no need to add it the 
second time in your bbappend. Just doing the standard FILESEXTRAPATHS_prepend 
trick in your bbappend should be enough to get it loaded in place of standard 
meta-ti config stuff.

What is your layer's BBFILE_PRIORITY? And where exactly do you add it to 
BBLAYERS list in your conf/bblayers.conf file?
