标题: 如何访问底板上特定规格的GPIO接口


我的需求是通过JD4主板上的 GPIO 接口，接入4路 3.3V （来自4个外部传感器）电平信号。
即我有4个外部传感器，它们共 输入/输出 4路3.3V 电平信号，所以需要板子提供3.3V 电平信号的 GPIO 接口4个。
查看了文档，搜索 GPIO 关键字，好像只能看到以下几个相关信息：






所标注的3个接口中，一个注明电平是3.3V，一个注明电平为1.8V，一个为空。


请问：
如何增加我所需要规格的GPIO接口数？
如何在 Python 代码中引用到这些接口？

1、GPIO2_C0和GPIO0_D6是输出和输入3.3V。另外两个GPIO的话就需要你自己从底板里面引出来了。
2、python 调用就是普通的 gpio 口调用方式

那么在调用GPIO2_C0和GPIO0_D6时针脚号pin是多少呢

你可以看下官网的维基教程：https://wiki.t-firefly.com/iCore-3568JQ/driver_gpio.html
这些都是通用的

谢谢，可以计算得到pin number, GPIO2_C0 pin 80可以正常使用，但是GPIO0_D6 pin 30不能使用，通过echo 30 > /sys/class/gpio/export导出时报错:-bash: echo: write error: Device or resource busy,
是因为这个口已经被使用了吗？

为什么一块板子上只有这么少的gpio口是可用的呢？有没有哪些针脚可能是共用的呢？可以作为gpio口也可以作为其他功能针脚呢？

1、规格书标错了，GPIO0_D6 应该改成 GPIO1_A1 。
2、GPIO口是很多的，但是需要配合底板的功能使用。一般都是买核心板然后根据需求自己制作底板的。如果不想自己制作底板，只能根据规格书将你使用到的GPIO引出来了

多谢回复。

关于问题2：
直觉上，一块底板只有2个默认引出的GPIO，是不是也太少了呢？ 请问有什么临时的办法，让我不用自己去做一块底板，而用比较简单的方法额外让我现在可以再引出2(共4）个GPIO吗?

你可以使用串口4当作GPIO普通管脚使用。分别是：（UART4_TX）GPIO2_A6 和 （UART4_RX）GPIO2_A7。需要在设备树rv1126-firefly-rk809.dtsi把uart4的配置关掉：

1. /*
   
2. &uart4 {
   
3.         pinctrl-0 = <&uart4m1_xfer>;
   
4.         status = "okay";
   
5. };
   
6. */

因为Linux了解较少，请问能帮忙提供一下编辑和应用 Rv1126 Linux Device Tree 的步骤或者文档吗？我甚至没有找到 rv1126-firefly-rk809.dtsi 文件的位置。

你可以用 fine -name xxx 搜索一下。具体路径在：sdk/kernel/arch/arm/boot/dts/rv1126-firefly-jd4-BE-45.dtsi

1, 改成GPIO1_A1后算出pin 为33， 可以通过echo 33 > /sys/class/gpio/export成功导出了，但是没能正确从这个引脚读到值。
我是这样做的：
在图中1处的引脚出使用5v跟接地，接到我的传感器上，在同一处的gpio（pin80）口上可以正确读到传感器触发后的值
然后保持传感器接入电源不变，把输出信号接到 pin33（图中2处），不能正确读到值了
问题:
图中1处 2处所用的GND 是相同的吗？我可以这样把用图中1处的作为传感器输入电源，把传感器输出接到图中2处吗？

你先确定管脚是否可以设置高低电平？不能的话要进行：echo out > direction 来设置 GPIO 为输出模式。然后再echo 1 > value设置高电平。万用表去量，看看是不是有电平变化。

如果有电平变化的话，那就没问题了，剩下就是你的软硬件调试了。

1. firefly@firefly:/$ sudo find -name rv1126-firefly-jd4-BE-45.dtsi
   
2. firefly@firefly:/$
   

复制代码

我用上述命令并未搜索到相应的文件，同样采用统配符：

1. 
   
2. firefly@firefly:/$ sudo find -name *.dtsi
   
3. firefly@firefly:/$
   

复制代码

也没有搜索到任何内容。

这是我rv1126板子上的根目录结构，似乎并没有 sdk/kernel/arch/arm/boot/dts/ ：

1. firefly@firefly:/$ ls /
   
2. bin   dev  home  lost+found  mnt  proc  root-ro  sbin  sys  userdata  var
   
3. boot  etc  lib   media       opt  root  run      srv   tmp  usr       vendor

复制代码

我使用的是firefly 官方的 debian 10 系统，请帮忙再确认一下文件路径。

你有下载firefly官方的RV1126 SDK开发包吗？不是在板子上跑find命令，是在PC电脑上跑。使用find命令查找的SDK文件在哪里。
你先看下维基教程和相关的开发流程吧。内核需要在PC上面编译烧录进板子，不是直接在板子上编译的。

谢谢回复。
我已经在 Ubuntu 20.04.4 (x64) PC机上安装了SDK: rv1126_rv1109_linux_release_20211022，在修改了文件 ./kernel/arch/arm/boot/dts/rv1126-firefly-rk809.dtsi 到你提供的示例内容：

1. /*
   
2. &uart4 {
   
3.         pinctrl-0 = <&uart4m1_xfer>;
   
4.         status = "okay";
   
5. };
   
6. */

复制代码

后，再运行：

1. ./build.sh device/rockchip/rv1126_rv1109/aio-rv1126-jd4-BE-45.mk

复制代码

• 尝试进行部分编译
  我理解我当前的改动是仅需要单独编译 kernel:
  1. ./build.sh kernel

  复制代码
  
  似乎并不成功，以下为编译结果的日志：

首先，默认使用的编译环境是ubuntu18.04，已经经过验证过编译不会出错。如果不是ubuntu18.04则需要自行安装原装的ubuntu18.04或者使用docker 安装ubuntu18.04进行编译开发。如果不想使用ubuntu18.04，则只能自行解决编译问题。
其次是刚拿到的sdk是一个基础包，需要进行更新最新才可以，维基有介绍怎么更新。

就是指通过wiki中说明的命令：

1. .repo/repo/repo sync -c --no-tags

复制代码

进行的意思，是吗？
