Why SVN if Poky already moved to GIT, you may ask. Well, we feel fond of that revision because we know it to work. Feel free try Poky's GIT or a newer SVN revision. In fact, you might want to take a look at Poky OMAP too.
Add Texas Instruments' overlay
cd $POKY git clone git://github.com/mturquette/meta-texasinstruments.git git checkout ddiaz/gitomapzoom
cd $POKY/build cp -p $POKY/meta-texasinstruments/conf/misc/local.conf local.conf
Review the above file.
With newer kernels exmap complains about missing headers. For now, you can have the rest of the profiling tools by taking exmap-console and exmap-server out of "RDEPENDS_task-poky-tools-profile" in $POKY/meta/packages/tasks/task-poky-tools.bb. This is needed for a Sato image.
cd $POKY source poky-init-build-env bitbake omap-image-min-gst
Alternatively, you can build a complete Poky Sato image:
You can find your binaries here: $POKY/build/tmp/deploy/images/.
cd $POKY/build/tmp/deploy/images/ ls -1s [ADD DIR LISTING HERE]
The kernel and u-boot can be copied to the boot partition on your MMC/SD card. Take the image tarball and untar it in the root partition of your MMC/SD card; also, untar the modules tarball on the root of your file system.
What are the most important recipes around here? Here's a list of them.
A recipe for u-boot can be found here: $POKY/meta/packages/uboot/u-boot-omap3_git.bb. This comes from Poky. You can try with another recipe for u-boot as long as it works on the Beagle. See $POKY/meta-texasinstruments/conf/machine/beagleboard.conf if you want to change it.
Kernel recipe is $POKY/meta-texasinstruments/packages/linux/linux-beagle_git.bb. This kernel, kindly forked by Felipec, is currently based on 2.6.28-omap1, with dspbridge patches on them. This is the GIT repository for it, see under the tidspbridge-stable branch: http://github.com/felipec/linux-omap/.
