You can do 'cat /proc/cmdline' to see the kernel command line in Linux.

most people do not keep u-boot resident once Linux has booted -mike
Im developing my own kernel which uses uboot. I want to jump to the uboot command line on using the exit syscall. Linux is not involved.
Can you tell me how I can reach the command line when i use the exit system call???

either software reset and let u-boot boot like normal, or dont overwrite any of the u-boot code/data sections. then just return to it.
look at the u-boot stand alone application examples -mike

This also means that you must not overwrite (or restore before return) U-Boot's exception vectors.

The most reliable way is by performing a hard reset of your system, i. e. a reboot.
