Of course I tried it but simply not work.
U-Boot-mONStR> fdt list /chosen
chosen {
bootargs = "console=ttyUL0,115200 highres=on root=/dev/mtdblock0";
linux,stdout-path = "/p...@0/ser...@84000000";
};
U-Boot-mONStR> fdt set /chosen bootargs console=ttyUL\ root=dev
U-Boot-mONStR> fdt list /chosen
chosen {
bootargs = "root=dev";
linux,stdout-path = "/p...@0/ser...@84000000";
};
