I got my inspiration from The Raspberry Pi Hobbyist and The EmbeddedHobbyist
The first is obviously not for BBB (but Linux is Linux) and the second one didn't really make any sense to me =)
First flash the BBB with Ubuntu using the instruction found on Circuitco homepage.
But unfortunately the direct link to the image is broken, this is the image i used: BBB-eMMC-flasher-ubu...
When flashing is done, remove SD-card and reboot the BBB
After that i logged on to the BBB and became root (username: ubuntu password: temppwd):
#sudo su (bad practice, i know but I'm lazy)
Next partition the hard drive (make sure you know what you're doing here)
#fdisk /dev/sda
Delete any old partitions using d.
Create new partitions with n
I made 3 partitions, 1 for the OS (20 GB), 1 swap (2 GB) and 1 for data (whatever left), in fdisk it looked like this:
OS Partition:
n (new)
p (primary)
<enter> (first available)
<enter> (start from first available sector)
+20G (make the size 20GB)
a (toggle bootable flag)
1 (partition 1)
Swap partition:
n (new)
p (primary)
<enter> (first available)
<enter> (start from first available sector)
+2G (make the size 2GB)
t (change partition type)
2 (partition 2)
82 (Linux swap)
Data partition
n (new)
p (primary)
<enter> (first available)
<enter> (start from first available sector)
<enter> (last sector available)
Now were almost done, use p to list the new partition table and it should look something like this:
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 41945087 20971520 83 Linux
/dev/sda2 41945088 46139391 2097152 82 Linux swap / Solaris
/dev/sda3 46139392 312581807 133221208 83 Linux
Exit fdisk saving the changes by pressing w and enter.
Next prepare the swap partition:
#mkswap /dev/sda2
Format the data partition:
#mkfs.ext4 /dev/sda3
Copy the rootfs from eMMC to the first partition (assuming /dev/mmvblk0p2 is your current root, you can check this by using the mount command):
#dd if=/dev/mmcblk0p2 of=/dev/sda1 bs=32M conv=noerror,sync
After dd is complete, check the filesystem (-f for force check and -y for yes to all questions):
#e2fschck -fy /dev/sda1
Next, resize the filesystem to match the partition:
#resize2fs /dev/sda1
Now its time to make some changes to our rootfs to be, start with mounting /dev/sda1:
#mount /dev/sda1 /mnt
Copy the kernel, uboot etc to the hard drive:
#cp -pvrf /boot/* /mnt/boot
And at last, change the uEnv.txt om the eMMC (not the hard drive)
#nano /boot/uboot/uEnv.txt
Find the line looking like this:
mmcroot=UUID=9363f4b4-869d-48ae-861e-80b18fc1a734 ro
Change it to look like this:
mmcroot=/dev/sda1 ro
Save and quit nano.
Make sure everything is saved:
#sync
Reboot and hold thumbs =)
If the system boots correctly, log in and make sure were running from hdd:
#mount
Look for the line:
/dev/sda1 on / type ext4 (rw)
