为什么按照文档编译出来的boot.img ,升级进去，HDMI没有声音输出呢？
kernel log中HDMI的声卡是注册成功的。

我升级Firefly-rk3288_Ubuntu_1604_2016_10261641_NO_VGA_Beta.img这一版，HDMI就有声音，是不是https://github.com/T-Firefly/firefly-3.14-kernel这个版本的HDMI声音还没调试好？

我前面的步骤都能正常通过，求解为什么在mkkrnlimg 时报错;mkkrnlimg command not
老大, 問一問幾個常識性問題
我在WIKI看到內核跟主線內核, 區別在哪?
另外, 我手上的板本身是在跑3.10.0 ubuntu 14.04, 想把它的內核升級為4.4, 應該看哪幾個教學?
https://github.com/T-Firefly/firefly-3.14-kernel
该源码对应固件那个版本的，4.4还是5.1的，为为什么的还有的版本是5.0呢？
make -j4 zImage 成功。
接下来make firefly-rk3288.dtb失败，请问什么原因
edm@ubuntu:~/UbuntuDev/firefly-3.14-kernel-master$ make firefly-rk3288.dtb
DTC arch/arm/boot/dts/firefly-rk3288.dtb

版主大人, 这个内核menuconfig里Virtualization项是空的... 如果想要做虚拟化, 装KVM的话怎么弄呢?

这个问题解决了吗？我也遇到了和你一样的问题？根据错误提示，说是缺少了rockchip,rk808.h这个库文件，但是我按照路径查找，能找到这个文件啊。
