uboot通过cmdline传参到内核

乔冰

//将参数传给bootargs
char uboot_time[12];
char *commandline = getenv("bootargs");sprintf(uboot_time, "%d", get_time());




//内核解析
static char *uboot_time;

static int __init  uboot_time_setup(char *str)
{
    uboot_time = str;
    return 0;
}
__setup("uboot_time=", uboot_time_setup);

//测试结果
