Hi,

I've put the linux to the embedded device. It use RedBoot bootloader to load the kernel and I can't change command line parameters that are provided to the kernel.

Now the params are: console=ttyS0,38400

What I need is: console=ttyS0,38400 root=/dev/mtdblock2 ro

Is there any possibility to hardcode/overwrite command line or add new param on runtime, for example inside a module (I could add some code to the MTD map driver).

I found function __setup and tried to use it like this:

__setup("root=", "/dev/mtdblock2 ro");


but I receive this error during compilation:

drivers/mtd/maps/rdc3210.c:56:1: error: pasting "__setup_str_" and ""/dev/mtdblock2 ro"" does not give a valid preprocessing token


Thanks,
Dawid
