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 ...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、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 ...
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。

firefly@firefly:/$ sudo find -name rv1126-firefly-jd4-BE-45.dtsi
firefly@firefly:/$
我用上述命令并未搜索到相应的文件，同样采用统配符：
firefly@firefly:/$ sudo find -name *.dtsi
firefly@firefly:/$
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/ ：
firefly@firefly:/$ ls /
bin devhomelost+foundmntprocroot-rosbinsysuserdatavar
bootetclib media optrootrun srv tmpusr vendor
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：
/*
&uart4 {
pinctrl-0 = <&uart4m1_xfer>;
status = "okay";
};
*/后，再运行：
./build.sh device/rockchip/rv1126_rv1109/aio-rv1126-jd4-BE-45.mk

请问我的步骤是否哪里有错误呢？

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， ...
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。

好的，我再去使用指定的 Ubuntu系统。
问题：
[*]请问针对于我的改动（改1个串口为2个gpio口），是否只要./build.sh kernel 就足够了呢？
[*]根据您说的：
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：
.repo/repo/repo sync -c --no-tags进行的意思，是吗？
