mq-r t113 开启gt9xx触摸屏不生效上电报错日志，有大佬帮忙看看吗？

MQ-R 触摸屏挂在iic2 ,原理图

/device/config/chips/t113/configs/evb1_auto/board.dts 配置如下，不确定PB2 PB3这样配置对不对

&twi2 {
	clock-frequency = <400000>;
	pinctrl-0 = <&twi2_pins_a>;
	pinctrl-1 = <&twi2_pins_b>;
	pinctrl-names = "default", "sleep";
	/*twi_drv_used = <1>; */
	dmas = <&dma 45>, <&dma 45>;
	dma-names = "tx", "rx";
	status = "okay";

		ctp@14 {
		compatible = "allwinner,goodix";
		device_type = "ctp";
		reg = <0x14>;
		status = "okay";
		ctp_name = "gt9xxnew_ts";
		ctp_twi_id = <0x2>;
		ctp_twi_addr = <0x14>;
		ctp_screen_max_x = <0x320>;
		ctp_screen_max_y = <0x1E0>;

		ctp_exchange_x_y_flag = <0x0>;
		ctp_int_port = <&pio PB 3 GPIO_ACTIVE_HIGH>;
		ctp_wakeup = <&pio PB 2 GPIO_ACTIVE_HIGH>;
		};
};

已找到报错的对应代码

[huanian]

已解决，引脚重复配置的问题，把PB2重复的地方去掉就可以

[wankle]

我的也是无法生效，能说一下PB2在哪里重复了吗？我没有查到。

@wankle 我也遇到了这个问题，你解决了吗？
