D1 PD1&PD2引脚复用出现错误
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!
设备树引脚配置
两个引脚输出的情况!
求有关大佬考证解答!

Re: D1 PD1&PD2引脚复用出现错误
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!

Re: D1 PD1&PD2引脚复用出现错误
情况并没有改善,开启 uart2 后,信号又出现了!

Re: D1 PD1&PD2引脚复用出现错误
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.
