How does one tell u-boot to tell the Linux kernel which runlevel to boot to?

Question

I would like to order u-boot to enter a specific runlevel lower than the one the system boots to. How does one accomplish this?

Thank you.

Answer 1

After a lot of digging before and after my question, I discovered that it's as simple as appending the number of the runlevel onto the end of the environment variable bootargs.

For instance, to enter into runlevel 3:

setenv bootargs ${bootargs} 3

and you can use

printenv bootargs

before and after to check your changes.
