Gentoo on Beaglebone Black SD Install

[morpheus2051]

Hi,

thanks to armin76 for the tutorial at http://dev.gentoo.org/~armin76/arm/beagleboneblack/install.xml.
However gentoo did not boot after following the tutorial. So I am sharing what I did differently.

First I got a Beaglebone Black A5C. I installed gentoo on a 32GB Sandisk microsdhc class 10 card. So here are the changes:

1.: I had to change the partition type of the first partition to W95 FAT16 (LBA) and format it with mkfs.vfat -F 16. Partition is starting on sector 2048.
2.: I do not know why this is the case but I had to place am335x-boneblack.dtb and uImage in /boot on the rootfilesystem (/dev/mmcblk0p2). On /dev/mmcblk0p1 I have only MLO and u-boot.img.
3.: Made a little swap partition (this is optional).

The only thing I have not figured out so far is that the mac address changed when I first booted the black on an other network. Note it did not change during reboots, poweroff or while booting an other kernel. Perhaps anybody here knows why this happened.

Greetings morpheus
