mipsandroid 遥控器设置
参照官网文档，在UBUNTU上编译mipsandroid，放置到SIGMA8655上测试运行。运行前必须修改相关文件
显示输出设置
如果不设置正确输出，屏幕上没有信号。
找到文件根目录下/system/etc/init.smp86xx.sh,将720P的输出改成
set_outports -digital -f HDMI_720p59 -component -f 720p59 -analog -f NTSC_M -audio_engine 0
遥控器按钮映射
Android中遥控器键值将映射成Android能处理的键值。因此mipsandroid必须加载两个驱动
insmod /lib/modules/virt_input.ko //虚拟输入驱动
insmod /lib/modules/irkernel.ko //遥控器驱动
系统从遥控器驱动读取键值映射成标准键值后发给虚拟输入驱动
mipsandroid通过启动virinput程序完成转换，源码位于/mipsandroid/vendor/sigma/smp86xx/virtinput/virtinput.c

如果当前Android系统已经运行，KILL掉virtinput进程，重新运行该可执行文件。
