Have you tried formating the SD card right on the overo then moving the files from the pc to the SD card.

Ahh, one of the tech guys at Adeneo (who has been trying to help my odd-ball
situation) verified this, but also included that actually the XLDRSD.nb0
file is appended at the end of the xldrtocsd.raw file, and the sum of the
two makes the MLO (at least in the case of the TI SDK). The raw file must
hold some specific information that clues the OMAP35xx (haven't read all TI
Docs on this as of yet) how to handle the XLDRSD or is some form of
initialization for the nb0.
Either case, I have been reviewing through the SDK and without breaking any
NDA specific information I am coming to the conclusion that it might be SD
Disk Geometry specific...at least in my situation relative to the Adeneo
issues...as I am using a Kingston SD-C02G and it seems that many people are
using Sandisks...the folks at Adeneo can just format the SD cards as FAT32
under WinXP, copy the MLO, copy the EBOOT.nb0, and then the NK.bin and take
that SD card (Sandisk) and the same Overo-Fire and Tobi expansion board
loads it just fine with their MLO.
Sooo... since the SD-C02G Kingston "works" and is of the right "kind" of SD
Memory card, and after reviewing through the SD Initialization code...it
very well could be that someone at Adeneo...a long time ago...hardcoded
specific geometry that happened to be a "default" for Sandisk but was
different than the Kingston line, and as such I am not able to simply format
my Kingston and copy the MLO and EBOOT.nbo over as they are because the disk
geometry needs to be identical to their disk geometry (much like that which
is required by the Over Linux demo...but seeing as I already tried that
geometry configuration it seems theirs is different).
It sort of makes sense, as the MLO (first record in the MBR and small enough
to possibly "miss" the block size limit) and as such the MLO loads just
fine...but then the EBOOT does not because that would require actually
scanning past the very first block of the SD.
Which is now what I am looking into... :)
If you happen to know anything about this or my "guess" is just silly...
please do correct me as I would much rather be silly for a moment than dumb
for a lifetime! ;)
I recently documented using the TI EVM (BSQUARE) BSP on the
BeagleBoard. It should directly apply to the Gumstix Overo hardware,
short a few minor changes.
For your Adeneo demo I would expect XLDR, EBOOT, and NK.bin to be required.
Regarding MLO check the associated XLDR makefile.inc. I suspect it only
copies XLDRSD.nb0 to MLO when WINCEDEBUG=RETAIL.
If you use RETAIL XLDRSD.nb0 -> MLO, then it needs to be first file
written to SD card after FAT32 format. Single partition.
