#1 全志 SOC » D1 uart2功能可以用在PD1和PC1引脚上吗? » 2022-02-15 10:23:55

将 D1 的 PD1&PC1 引脚设定为串口复用功能,但是串口通信不成功,请问这是什么情况?
下面是设备树配置

	uart2_pins_a: uart2_pins@0 {  /* For EVB1 board */
		// pins = "PC0", "PC1";
		pins = "PD1";
		function = "uart2";
		drive-strength = <10>;
		bias-pull-up;
	};
	uart2_pins_b: uart2_pins@1 {  /* For EVB1 board */
		// pins = "PC0", "PC1";
		pins = "PC1";
		function = "uart2";
		drive-strength = <10>;
		bias-pull-up;
	};
	uart2_pins_c: uart2_pins@2 {  /* For EVB1 board */
		// pins = "PC0", "PC1";
		pins = "PD1", "PC1";
		function = "gpio_in";
	};


&uart2 {
	pinctrl-names = "default", "sleep";
	pinctrl-0 = <&uart2_pins_a &uart2_pins_b>;
	pinctrl-1 = <&uart2_pins_c>;
	uart2_type = <2>;
	status = "okay";
};

是全志芯片的一个隐藏问题,全志的 tcon 模块上电后会自己运行,然后在 PD 接口上发送信号.同时全志的 GPIO 引脚复用关系寄存器无法切断 tcon 信号的输出.我试过操作 PD_CFG0 寄存器,但是没有用.最后是无意中发现只要在全志的框架下关闭显示功能才能彻底停掉 tcon 信号.这个在使用 PD 组 复用 GPIO 时需要注意的问题.目前不知道全志 D1 裸机情况下会不会出现这个问题.期望开发全志 D1 裸机的大佬验证下这个问题.

情况并没有改善,开启 uart2 后,信号又出现了!

#4 Re: 全志 SOC » D1 PD1&PD2引脚复用出现错误 » 2022-02-12 14:12:35

卸掉 fb 模块后,引脚电平正常了.看样子是芯片的 disp 模块会强制在该引脚上输出一个信号.复用寄存器都屏蔽不掉这个信号.
比较坑的是,就算屏蔽了 fb 模块的设备树节点, D1 芯片的 disp 模块还是在工作,还是会输出一个信号.
简单的说就是 gpio 复用寄存器无法切断 disp 模块输出的信号.这是一大坑呀!

最近使用 D1 时,想要使用 PD1&PD2 的串口复用功能.结果这个两个引脚一直在输出一个脉冲信号.改变了引脚复用关系寄存器后信号还在.
不知道是不是芯片自身的硬件引脚 bug.求大佬解答!

@LinjieGuo 去掉冒号, 那个地方是荔枝派文档挖的大坑。

u-boot 的 bootcmd 里面 sf probe 0:500000

上面命令行的冒号。

绝了绝了,哈哈。后面的文档已经在改了。坑呀坑呀就习惯了,哈哈!

博流的BL702有点坑,芯片上电第一次运行程序速度要远远慢于正常速度。这个坑在写严格时序程序时非常烦人。还有就是linux下的gcc编译,简直就是反人类。直接把我写的时序代码给优化掉了,延时函数直接删除,我人都傻了!
