荔枝派nano 电阻触摸屏问题请教

最近在测试NANO的配套例程时发现以下不能打开evdev设备的错误,详细如下:

# ./littlevgl_benchmark
The framebuffer device was opened successfully.
800x480, 32bpp
The framebuffer device was mapped to memory successfully.
Frame buffer hor. res: 800, ver. res: 480
unable open evdev interface:: No such file or directory

# ./littlevgl_demo_with_wallpaper
[   73.786008] random: crng init done
The framebuffer device was opened successfully.
800x480, 32bpp
The framebuffer device was mapped to memory successfully.
Frame buffer hor. res: 800, ver. res: 480
unable open evdev interface:: No such file or directory

这个应该时电阻触摸驱动NS2009还没加载上去的原因把,有人遇到过这个情况吗,有没有解决的大佬给解答下吗
