I had something similar, it turned out that the MLO file on the card was
not written the way it was needed, so X-Loader was ignoring it and
reading NAND. Formatting the fat partition again and copying MLO as the
first file got it working. If you check the output when you boot your
card on a working Overo, make sure you see:
Texas Instruments X-Loader 1.4.2 (Jan 13 2010 - 06:59:23)
Reading boot sector
Loading u-boot.bin from mmc
..and not nand.
