This is too late for debug. The same result I can see when my card is not inserted.
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:
You should follow the card init sequence with the trace config, because it fails at init. This is the trace output from init sequence of my SD card:

* MMC_RSP_R3,4 0xC0FF8000* 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 hope this will help you to solve this issue.
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.
