I've been reading about changing u_boot parameters, but I actually have no idea how to get a u_boot prompt to do this.  i.MX53 QSB.  I created a new boot microSD using the instructions on freescale, and the machine boots just fine, but I never see any kind of prompt before getting the Ubuntu desktop.  I see a penguin in the upper left corner, then nothing until boot is complete.


Did I mess up the microSD flashing?  Is there some key sequence I need to hit during the boot process?  How can I get a u_boot prompt in order to change some of the boot parameters?
