Configuration management

• You can make something machine specific by placing it in a subdirectory:

• Or by specifying them in the recipe itself:

../linux/linux-omap-2.6.29/overo/defconfig

../linux/linux-omap-2.6.29/omap3evm/defconfig

../linux/linux-omap-2.6.29/beagleboard/defconfig

../linux/linux-omap-2.6.29/omapzoom/defconfig

../linux/linux-omap-2.6.29/omap3-touchbook/defconfig

TI support in Angstrom and OE

• TI gstreamer plugins for omap3, davinci, etc• SGX drivers and libs (1.4.14.2514), close

collaboration with ASP gfx team• OpenGL|ES support for QT 4.5.2• NEON optimizations for pixman and ffmpeg• Angstrom has everything compiled for armv7a

on omap3 platforms

TI support in Angstrom and OE

• Good integration os dsplink/codec-engine thanks to close collaboration with component owners.

• Various customers using it in production (e.g. Panasonic)

Future

• Closer collaboration with WTBU• Standardize on one OE ‘flavour’, namely

Angstrom instead of different ones (e.g. Poky)• Integrate Braveheart stack
