更新resource.img和kernel.img没变化

Chip Platform Rockchip

按着这哩弄hello-led,http://developer.t-firefly.com/forum.php?mod=viewthread&tid=648&extra=page%3D1
1、在drivers文件夹下建文件夹sai
2、在sai下放好hello.c,makefile,kconfig
3、在dirvers下的makefile,kconfig添加好东西
4、在kernel下make menuconfig设置hello编译到内核
5、make
6、烧录resource.img和kernel.img
重启板子，发现led并没有闪
dts我是这样改的：
firefly-led{
compatible = “firefly,led”;
led-work = <&gpio1 GPIO_C7 GPIO_ACTIVE_LOW>;
led-power = <&gpio1 GPIO_C6 GPIO_ACTIVE_LOW>;
status = “disabled”;
};

    hello-led{
            compatible = "firefly,hello_led";
            led= <&gpio1 GPIO_C6 GPIO_ACTIVE_LOW>;//这里我改成黄色的灯
            status = "okay";
    };

    leds {
   compatible = "gpio-leds";
   power {
       label = "firefly:blue:power";
       linux,default-trigger = "ir-power-click";
       default-state = "on";
       gpios = <&gpio1 GPIO_C7 GPIO_ACTIVE_LOW>;
   };
    user {
       label = "firefly:yellow:user";
       linux,default-trigger = "ir-user-click";
       default-state = "off";
       gpios = <&gpio1 GPIO_C6 GPIO_ACTIVE_LOW>;
       };
    };

hello.c里关键是这样的：
#ifdef CONFIG_OF
static const struct of_device_id of_firefly_hello_match = {
{ .compatible = “firefly,hello_led” },
{ /* Sentinel */ }
};
#endif

static struct platform_driver firefly_hello_driver = {
.probe = firefly_hello_probe,
.remove = firefly_hello_remove,
.driver = {
.name = “firefly_hello”,
.owner = THIS_MODULE,
#ifdef CONFIG_OF
.of_match_table = of_firefly_hello_match,
#endif
},

};

查看板子的dmesg也没看到hello模块加载的printk，请问我哪里弄错了呢？

2

补充一下，在源码目录里可以看到hello.c文件有被编译

3

有可能是boot。img里面包含了kernel，会默认先使用里面的kernel，不包含kernel的boot一般1点多m

4

接串口看一下log信息，看打印出来的内核编译时间是不是你编译的时间，可以确定板子是否运行你编译的内核

请问怎么看内核编译的时间？

谢谢linjc，之前是出厂的双系统，现在更新到官方的案桌单系统就可以了，终于看到黄色的LED闪10下。
