Well I create barebox.bin.itf with xloader_defconfig copy to SD card
renamed to MLO.
Create barebox.bin copy to SD card.
Output which I got is:

barebox 2011.04.0-00158-g2153636-dirty (Jun 20 2011 - 19:50:23)

Board: Texas Instrument's Panda
PandaBoard Revision: 003
omap_mmc_probe <- debug where it just hang.

@Jan: Which board revision you have?
I have bad feeling it has something to do with SD cards which I have?

Thanks for replies.
