The device is in DFU-mode when you see this in dmesg:

Out of curiosity, were you forced to use SAM-BA? Somehow our expectation is
that SAM-BA is only used as last resort.
NFC-tests are part of my work package, but it looks
like the board requires
some shielding. The 13MHz antennas seem to disturb the operation on the
simtrace-boad. Will find a solution and report back to the community.
We had this topic at the OsmoDevCon2012 and the mentioned solution was:
"NFC and SIMtrace FPC... interference... 13..Mhz NFC magnetic coupling -> use
copper tape as shielding"
