20260113给飞凌OK3588-C开发板适配Rockchip原厂的Android14系统时点亮飞凌的7寸屏时适配CTP触摸屏FT5X06
2026/1/12 20:22
缘起：给飞凌OK3588-C开发板适配Rockchip原厂的Android14后，需要适配CTP触摸屏FT5X06。
当你把荣品RD-RK3588开发板重新适配一把，就相当于从头做了一个项目：【荣品RD-RK3588开发板】。
当然，开发板的功能都是好的，你免除了调试的过程，也就没有解决相关硬件出错的经验/机会了！
1、在DTS的i2c2中挂载CTP触摸屏FT5X06
【下次如果没有的I2C节点要首先注意I2C的冲突了】
如果不指定i2c2的引脚复用，那默认就是i2c2m0了
pin 15 (gpio0-15): feaa0000.i2c (GPIO UNCLAIMED) function i2c2 group i2c2m0-xfer
pin 16 (gpio0-16): feaa0000.i2c (GPIO UNCLAIMED) function i2c2 group i2c2m0-xfer

4、确认edt-ft5x06.c编译成为edt-ft5x06.o了，但是CTP还是不能用。
getevent也没有打印信息。
dmesg | grep ft5
【确认CTP的驱动程序没有被挂载！】
Y:\new_disk_4t\wyb\OK3588-C\RK3576_Android14.0_SDK_RELEASE\kernel-6.1\drivers\input\touchscreen\edt-ft5x06.o
【应该不用修改】
Y:\new_disk_4t\wyb\OK3588-C\RK3576_Android14.0_SDK_RELEASE\kernel-6.1\drivers\input\touchscreen\edt-ft5x06.c
5、
保险起见，替换掉edt-ft5x06.c【无效】
6、这时候想起来可能是GPIO冲突了，重点关注I2C2
【现阶段异常的】
pin 15 (gpio0-15): vcc-3v3-sd-s0-regulator gpio0:15 function sdmmc group sd-s0-pwr
pin 16 (gpio0-16): (MUX UNCLAIMED) (GPIO UNCLAIMED)
【预编译的Android14】
pin 15 (gpio0-15): feaa0000.i2c (GPIO UNCLAIMED) function i2c2 group i2c2m0-xfer
pin 16 (gpio0-16): feaa0000.i2c (GPIO UNCLAIMED) function i2c2 group i2c2m0-xfer
根据经验/很容易得知：gpio0-15/GPIO0B7被sd-s0-pwr占用了
Y:\new_disk_4t\wyb\OK3588-C\RK3576_Android14.0_SDK_RELEASE\kernel-6.1\arch\arm64\boot\dts\rockchip\rk3588-evb7-v11.dtsi
vcc_3v3_sd_s0: vcc-3v3-sd-s0-regulator {
compatible = "regulator-fixed";
// 2026/1/12 21:04 wenyuanbo i2c2
//gpio = <&gpio0 RK_PB7 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
//pinctrl-0 = <&sd_s0_pwr>;
regulator-name = "vcc_3v3_sd_s0";
enable-active-high;
};
// 2026/1/12 21:04 wenyuanbo i2c2
//sdmmc {
// sd_s0_pwr: sd-s0-pwr {
// rockchip,pins = <0 RK_PB7 RK_FUNC_GPIO &pcfg_pull_up>;
// };
//};
