Ugh, I meant to include the link to my post in the odroid forums which
included the entire (very long) output:
http://forum.odroid.com/viewtopic.php?f=13&t=2883#p76524
I'll inline compare my lines with yours, and prepend and append '*' to
those that differ:

At the moment, I don't know what that command corresponds with, but I
see the 55 and 41 are repeated 1 more time with yours before getting
that 41 output that I have. Perhaps it's a timing/retry attempt on
your system.

I searched my output for any "ret" value < 0 and it was only for "CMD_SEND:16"
I should also add that I'm using odroid U2.
My output also doesn't stop at command 12. In fact I get an error
right after it: "*** Warning - bad CRC, using default environment".
But then that should be expected since I wipe blocks from 2560 to the
start of my first partition.
After that I get a bunch of 12, 16, 17, 18 commands (mostly 16, 17).
Thanks for taking the time to look into this issue.
