20251107给荣品RD-RK3588-MID开发板跑Rockchip的原厂Android13系统时适配8寸屏的CTP【使用荣品的DTS】
2025/11/7 10:15
缘起：给荣品RD-RK3588-MID开发板跑Rockchip的原厂Android13系统。
但是WIFI/BT模块的AP6275P的WIFI/BT都不能打开！
一般认为是Rockchip的Android13的mk文件语法识别识别，编译内核的时候没有加载pcie_wifi.config。
结果默认配置成为AP6256了？
在使用荣品的DTS的时候，LCD屏很容易就点亮了，但是CTP触摸屏没有反应。
调试过程/步骤：
1、很容易知道没有加载gt9xx的驱动程序。
Y:\new_disk_4t\wyb\RD-RK3588\EVB7_RD-RK3588t\kernel-5.10\.config
Y:\new_disk_4t\wyb\RD-RK3588\orig_RD-rk3588_Android13\kernel-5.10\.config
CONFIG_TOUCHSCREEN_ROHM_BU21023 is not set
CONFIG_TOUCHSCREEN_IQS5XX is not set
CONFIG_TOUCHSCREEN_ZINITIX is not set
CONFIG_TOUCHSCREEN_GT9XX=y
CONFIG_ROCKCHIP_REMOTECTL=y
CONFIG_ROCKCHIP_REMOTECTL_PWM=y
2、很容易知道，荣品将Rockchip的原厂Android13系统中kernel内核中的CTP触摸屏驱动程序V2.2版本升级成为V2.4版本了！
Y:\new_disk_4t\wyb\RD-RK3588\orig_RD-rk3588_Android13\kernel-5.10\drivers\input\touchscreen\gt9xx\goodix_tool.c
Y:\new_disk_4t\wyb\RD-RK3588\EVB7_RD-RK3588t\kernel-5.10\drivers\input\touchscreen\gt9xx\goodix_tool.c
将Rockchip的原厂Android13系统中原版的gt9xx的驱动和 gt9xx_bk备份的比对，完全一致！^_
Y:\new_disk_4t\wyb\RD-RK3588\orig_RD-rk3588_Android13\kernel-5.10\drivers\input\touchscreen\gt9xx_bk\gt9xx.c
Y:\new_disk_4t\wyb\RD-RK3588\EVB7_RD-RK3588t\kernel-5.10\drivers\input\touchscreen\gt9xx\gt9xx.c
3、加载gt9xx的驱动程序
Y:\new_disk_4t\wyb\RD-RK3588\orig_RD-rk3588_Android13\kernel-5.10\arch\arm64\configs\rockchip_defconfig
Y:\new_disk_4t\wyb\RD-RK3588\EVB7_RD-RK3588t\kernel-5.10\arch\arm64\configs\rockchip_defconfig
CONFIG_RUNTIME_TESTING_MENU is not set
CONFIG_RP_POWER=y
CONFIG_RP_GPIO=y
CONFIG_RP_STM706=y
CONFIG_TOUCHSCREEN_GT9XX=y
CONFIG_WERROR is not set
CONFIG_USB_SERIAL_FTDI_SIO=y
CONFIG_CAN_MCP251X=y
Y:\new_disk_4t\wyb\RD-RK3588\EVB7_RD-RK3588t\kernel-5.10\drivers\input\touchscreen\Kconfig
Y:\new_disk_4t\wyb\RD-RK3588\orig_RD-rk3588_Android13\kernel-5.10\drivers\input\touchscreen\Kconfig
config TOUCHSCREEN_ZINITIX
tristate "Zinitix touchscreen support"
depends on I2C
help
Say Y here if you have a touchscreen using Zinitix bt541,
or something similar enough.
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called zinitix.
config TOUCHSCREEN_GT9XX
tristate "gt9xx touchscreen support"
depends on I2C
help
Say Y here if you have a touchscreen using gt9xx,
or something similar enough.

endif

obj-(CONFIG_TOUCHSCREEN_ZINITIX) += zinitix.o obj-(CONFIG_TOUCHSCREEN_GT9XX) += gt9xx/
4、通过getevent确认CTP已经挂载了！
