As far as I'm aware yes, standard C4 from digikey.

I've done a little more searching, and found that adding #define DEBUG
to /arc/arm/lib/board.c brings up more detailed info.

At that point my total lack of c knowledge kicked in and I gave up!

I'm currently downloading the denx u-boot from git, so will give that a
try and see if it reports anything different.

The reason for going for a source option is I have an odd problem with
my pandaboard not reading the mmc with various versions of u-boot so
decided to go back to the beagleboard to see if the problem was the
same, and if not then at least have an idea where to start from with the
pandaboard... but I digress!
