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.
