Status of Beaglebone (White) and Micro
- The Micro has support in buildroot
- Buildroot is getting support The BeagleBone (white) and black.  It is in process; in the mean time, here is a simple way to get it working

1. create a directory bealgebone

2. git clone git://git.buildroot.net/buildroot

   This will create a directory buildroot

3. For the kernel use https://github.com/beagleboard/kernel/tree/3.8 I download load via the zip link on the far right of the web page
4. unzip the file
5. run the ./patch.sh
6. Create a tar file: tar zvcf kernel linux-3.8.tar.gz 
7. copy the linux-3.8.tar.gz into the buildroot/dl directory.  This "stuffs" the kernel into the buildroot download tree
8. mkdir bld
9. cd bld
11. make -C ../buildroot/ O=$PWD beaglebone_defconfig
12. make
13. wait few hours

On of the issues when copying the image the most of the sdcard is not used.  To fix that do the following:

sudo resize2fs /dev/xxxx

the xxxx is the partition of the sdcard   this will expand the image until to space is filledd
