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?
You mean to say that it can be done so with the help of a RS232 Serial port also?
Because, I have tried and nothing could be done when the board is connected to RS232, But If I use USB2Serial, then its working fine.

When you power up the board, U-boot should come out on the serial console. You will have a few seconds to interrupt the boot process and get access to the U-boot prompt.
In order to interrupt the boot process just hit any key in the terminal (minicom/hyperterminal) during the very first seconds.
