Boot process hangs at 'waiting for root device ...'

I have a beagleboard with empty NAND and I have set up 2 sd cards (one
is 1GB Sandisk and other is 8GB SDHC, just to test...) according to
beginners' wiki page. Using minicom to communicate with BB, I power up
the board and it hangs at the "Waiting for root device /dev/
mmcblk0p2..." prompt... I'm using the files from the latest Angstrom

Here is the minicom output:

and here is the information of the SD card structure:

Any ideas?

the main idea is that the kernel dows not find any SD card inserted.
