编译:
masong@hydra:~/Coding/learnUbuntu/firefly-rk3288-kernel$ make ARCH=arm CROSS_COMPILE=arm-eabi- -j8 firefly-rk3288.img
最后出现这样就说明编译成功了
OBJCOPY arch/arm/boot/zImage
Kernel: arch/arm/boot/zImage is ready
Image:kernel.img is ready
Pack to resource.img successed!
Image:resource.img (with firefly-rk3288.dtb logo.bmp) is ready
你提出的es8323问题，我们会去跟进的。

感觉es8323启动中间异常了，有没有firefly的开发过来看下~
8323的驱动是android和ubuntu内核共用，create file失败是因为ubuntu没有/data目录，可以在probe中把路径改一下

ES8323 和 HDMI 是两个声卡，如果你要验证ES8323是否正常，可以使用aplay来播放wav文件测试。
可以验证es8323驱动是正常的，只是插上HDMI的线，会优先使用HDMI播放声音，当去除掉HDMI线时，耳机声音就正常了。
感觉音频es8323这块的问题好大
昨天查看的启动信息补全，完全的是这样的

写好的东西不能加载进去，直接使用阿sai的hello模块，使用insmod插入提示为:

Segmentation fault
查看了下模块信息如下:
root@firefly:~/Coding# modinfo hello.ko

查看了下内核记录如下:

谁来帮我解释下，一个printk就快要把我给搞疯掉!!!
.ko你自己编译的吗？不要用现成的.ko，在自己的内核里编译出来。
