佬们，请帮我看看，为啥我的屏幕顶部有一部分区域是无法触摸的，点击屏幕没有反应,点击其它区域倒是有反应

nlive 说：

linux写入错误导致的，CFG data错误，需要重新写入 gt11 0x8047-0x8100 186个寄存器。
参考裸机烧录例子：
https://gitee.com/dmcus/F1C200S/tree/master/sources/examples/gt911_4.3_800x480
修改 gt911_4.3.h #define GT9XX_SEND_CFG 1 。

看了下，裸机烧录超级麻烦呀，佬有没有Linux方面的解决办法

最后如同楼上的老哥说的一样，重新写一下GT911的寄存器就行了，参考这个https://wiki.sipeed.com/soft/Lichee/zh/Nano-Doc-Backup/driver/touchscreen.html
