BB C4 cannot boot up

Hi,

I tried to setup BB C4 by following instruction at:
http://code.google.com/p/beagleboard/wiki/HowToGetAngstromRunning

I actually get it worked once by hold on user button to boot from SD
card. I setup a user account and everything seems working fine. Then,
I hit RESET button to try to boot again. The screen always shows a
banner: beagleboard.org at top left corner of screen and remained
screen is black. Then, it stuck there forever.

Is there any solution for this? Thanks a lot for your help!

Boot output/debugging is via the RS232 serial connector.

seems like your SD card is not found.

Did you change bootargs arguments in u-boot?

Thanks for the response.

I didn't change anything. But, I finally get Angstrom working every
time now after I put usb keyboard and mouse into powered USB hub. It
could be SD card not found because I am using a microSD card and use a
card adaptor to put into beagle board.

Thanks a lot!
