f1c200s板上实现了linux 启动的qemu 模拟器(基于https://github.com/newluhux/qemu-f1c100s)。但是做的不完整，也算半途而废。
f1c220s主要的问题是旧了点，性能弱了点。
现在t113流行度也比较高，性能更强，支持驱动更大的屏。
虽然计划是在113上支持usb扩展显示器功能。
但是qemu模拟器还是会先搞到一个基础版本，方便解决调试linux/uboot的一些问题。
USB部分的问题其实也可以采用qemu来模拟，但是其实usb相对好开发，调试的问题不多。放在后面搞。
如果不先把qemu工具搞出来，放后面怎么有动力搞？
目前已经完成uboot/Linux SD boot done 进入shell. 当然剪掉了一些外设。
stage1 基本搞完了。
计划的功能：
stage1:
uboot
Linux
SDMMC
uart
stage2:
LCD display > 方便LVGL?其实x86也可以的。纯展示能实现grahic
stage3:
USB
