[U-Boot-Users] How to use kernel cmdline instead

[Junior]

Hi all,
How do I make uboot use the commandline args in embedded in the kernel
rather than those supplied by uboot?

Thanks.

Thanks. I'm actually refering to building. What option do I set or unset?
My build doesn't like when I unset CMDLINE_TAG, unless I messed something up.

Actually kernel will use buildtime option as default if nothing is passed as
boot time command line.
I guess you want to know how to use the kernel default ... then just pass
nothing to kernel. Make sure then that your kernel was well configured at build
time or you will most likely end up with a kernel panic at the time of mounting
root filesystem.

You cannot. U-Boot never uses any information embedded in the kernel.

For U-Boot, the kernel is just a binary blob of unknown (and
uninteresting) data.

Thanks,
On second thought, this might be a kernel thing. What I really meant is for the
kernel to boot with the embedded cmdline instead of using the one supplied by the 
bootloader.

As I known, it can be configured by "make menuconfig".

    From the U-boot command line you have to unset the bootargs 
environment variable.
    To do that :
    U-Boot> setenv bootargs
