Hi John,
I posted today a pretty comprihensive set of directions. Half are not actually
needed for the actual work but it takes into account as if you were starting
from ground zero. Please see down below.
I was able to finally get past the issue. Please see below for my long
winded directions:
1. Make sure your micro sd card has enough space.
2. Remove the micro sd card.
3. Boot off the emmc, once up and running,
4. In a terminal session "sudo" to root ( password = temppwd ) and stay as
root for the remainder of the steps.
5. Insert the micro sd card into the sd slot, umount the microsd card if the
O/S mounts it automatically.
6. "dd" the X15 image to a 32 gig micro sd card once "dd"
is complete,
7. cd into "/opt/scripts/tools"
8. Theres is a script called "grow_partition.sh"
9. I modified this script so that it looks at the micro sd card. In my case
the micro sd card is "/dev/mmcblk0". The line you are looking for
"drive=/dev/mmcblk0". I modified it so that theres is no mistake on which
storage device it will do it's work on. This may not be necessary
in your case.
10. Execute the script in the end it will expand the partition to the full
32 gigs.
11. Leave the micro sd inserted.
12. RE-Boot your X15, if it works your system's boot drive is the micro sd.
13. In a terminal session, "sudo into root and stay as root"
14. Connect your SATA or ESATA drive.
15. Make sure it is mountable and viewable.
14. Cd into "cd /opt/scripts/tools/developers"
15. Run the following command "git pull", once complete,
16. Run the following command "./secondary_rootfs.sh, once complete,
17. Mount the SATA/ESATA drive.
18. You will need to edit the /boot/uEnv.txt file on your microsd card,
19. comment the "uuid" line on the micro sd card and copy the one
that is on the SATA/ESATA drive, it's location will be something like
"/your_mount_point/sda1/boot/uEnv.txt". Dont replace the file!!
20. You should be able to reboot and the microsd card will now redirect
the boot process to your SATA/ESATA drive.
21. If you want to boot back to the micro sd card just comment the "uuid line.
22. You can also modify the emmc/boot/uEnv.txt file and it will redirect to
the SATA/ESATA drive.
Let me know how it works out for you
Good Luck
Angel
