我有nanopi2火。我想使用GT911触摸屏，我把这个goodix header file改成这样：（230-233行）
// STEP_2(REQUIRED): Customize your I/O ports & I/O operations
#define GTP_RST_PORT 16 //16 //S5PV210_GPJ3(6)
#define GTP_INT_PORT 17 //17 //S5PV210_GPH1(3)
这是关于gt9xx tp驱动程序说它连接到I2C0的s5p4418-nanopi2-common.dtsi（第466-473行）
goodix_ts@5d {
compatible = "goodix,gt9xx";
reg = <0x5d>;
interrupt-parent = <&gpio_c>;
interrupts = <16 IRQ_TYPE_EDGE_FALLING>;
goodix,irq-gpio = <&gpio_c 16 0>;
};
这是nanopi2的defconfig：
# CONFIG_INPUT_MOUSE is not set
CONFIG_INPUT_TOUCHSCREEN=y
CONFIG_TOUCHSCREEN_EDT_FT5X06=y
CONFIG_TOUCHSCREEN_FE_PANELS=y
CONFIG_TOUCHSCREEN_1WIRE=y
CONFIG_TOUCHSCREEN_GT9XX=y
CONFIG_TOUCHSCREEN_IT7260=y
CONFIG_TOUCHSCREEN_HIMAX=y
CONFIG_TOUCHSCREEN_ST1572=y
因此，我认为goodix是默认启用的。
当我交叉编译内核时，内核在更改gt9xx.h文件并复制zImage和DTB文件（as tutorials）之后，将SD与run the Linux一起运行，没有任何更改。
我测试了i2c，结果如下：
i2cdetect -y 0
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- UU
30: -- -- -- -- -- -- -- -- -- UU -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- 5d -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- -- --
我认为我的设备连接到i2c是正确的，但是触摸不起作用。此外，此命令不返回任何内容：
dmesg | grep goodix

最佳答案
您是否在内核中启用了goodix_ts驱动程序？在你的dmesg中似乎没有这种驱动程序的踪迹（也| grep goodix要么没有工作，要么你发送了错误的输出）。。。无论如何，检查drivers/input/touchscreen/gt9xx.c是否已编译。
关于linux - 未从Arm设备加载Goodix驱动程序，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/53790232/
