Buildroot f1c100s一键编译
编译flash
make licheepi_nano-flash_defconfig
make
编译ramdisk
make licheepi_nano-ram_defconfig
make
烧写flash
sudo ./up-flash.sh
在内存中运行
sudo ./up-ram.sh
nes模拟器编译与采蘑菇运行
cd board/f1c100s/apps/infones/linux
make
把InfoNES和Super_mario_brothers.nes复制到"output/target/root"
在回到f1c10s_buildroot目录下 make
sudo ./up-flash.sh 或 sudo ./up-ram.sh
运行嵌入式linux系统,登陆后在/root目录下运行
./InfoNES Super_mario_brothers.nes
修改核心添加RGB与BGR切换功能（画PCB时方便走线）
