kennel boot-parameters

normal we use bootloader paramer , but sometimes we may want to use extern

kernel-parameters,  or Always use the default kernel command string......

 

exampel 1:

extern  bootargs  under kernel 　　

Boot options --->
　　(quiet) Default kernel commmand string
　　Kernel command line type (Extend bootloader kernel arguments) --->

 

example 2:

use kernel command string

Boot options --->

        (initrd console=ttymxc0,115200) Defautl kernel command string

　　Kernel command line type(Always use the default kernel command string)  --->
