Goodix 触摸屏驱动模块加载了错误的 abs_x_max 和 abs_y_max

我正在为 raspberry-pi cm3 在 yocto 图像上加载 goodix 触摸屏驱动程序。当 pi 启动时。模块加载成功，但我得到的 abs_x_max 和 abs_y_max 值错误。

但是我的屏幕是 600X1024，而不是 800X480。为什么会发生这种情况？有没有办法重置 abs_x_max 和 abs_y_max？我可以通过设备树覆盖文件更改它吗？

答案1

所以我终于发现了。芯片上的固件是错误的。这导致屏幕分辨率为 800X480。一旦我更换屏幕。我现在可以看到 1024 X 600
