恢复原始官方固件后再试了, 旋转屏幕方向多次后, 触摸屏完全失效.- firefly@firefly:~$ cat /proc/version
- Linux version 4.4.154 (daijh@tchip14) (gcc version 6.3.1 20170404 (Linaro GCC 6.3-2017.05) ) #28 SMP Mon Mar 4 12:21:30 CST 2019

旋转屏幕时, 内核有错误信息如下:
- [ 490.333807] rockchip-vop ff900000.vop: [drm:vop_crtc_enable] Update mode to 800x1280p0, type: 16

另外, 旋转屏幕几次后, 遇到另一个现象, 屏幕上只有边缘的一小块区域触摸有效, 其他区域触摸无效. 随后再旋转几次, 就完全失效了.
