Hello Plumbedzero,
Here is what I did:

make omap3530_beagle_defconfig
make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi-

I use a 32MB SD card formatted for FAT.

As per documentation,
I copied the file MLO, barebox.bin as u-boot.bin and normal.scr as 
boot.scr (not used yet) on the SD card.

Texas Instruments X-Loader 1.4.2 (Feb 19 2009 - 12:01:24)
Reading boot sector
Loading u-boot.bin from mmc
