This are some experiments I've done (no genivi, vanilla (I think) yocto, very simple). Ros works :D

# POKY_BBLAYERS_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
POKY_BBLAYERS_CONF_VERSION = "2"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \

I've seen that meta-ros is full of projects inside! I still don't know how to select the rospackages to insall, but here I lest the minimum wee need to start:

• ros-comm
• std_msgs
• geometry_msgs
• sensor_msgs
• rosbridge_suite
• rosserial
