wiringPiSetup: mmap (PWM) failed: Invalid argument

[thedmdim]

Hello!

• orange pi zero h2+ 512mb
• Armbian_23.11.1_Orangepizero_jammy_current_6.1.63

I installed wiringOP like this:

git clone https://github.com/orangepi-xunlong/wiringOP.git
cd wiringOP
./build clean
./build

When I run gpio -v i get:

gpio version: 2.46
Copyright (c) 2012-2018 Gordon Henderson

For details type: gpio -warranty

  * Device tree is enabled.
  *--> Xunlong Orange Pi Zero

When I run gpio readall i get:

wiringPiSetup: mmap (PWM) failed: Invalid argument

Any suggestion how to get working gpio?

Maybe there is workaround? Actually I only need kinda toogle, so for example I press a button and there runned script.

Yes, I am seeing the same message on an Orange Pi PC2. It seems something changed in an update just a few weeks ago. A "next" branch vs "master" branch issue??
I downloaded and compiled the master release, and it seems to work, at least on the H5 based PC2 model.

Same issue. Thought it was something with trying to install it on Armbian 23.11.1 Bookworm but building off that master release works fine. Thanks for the direction.

while building from master.zip:
OrangePi.h:198:36: error: ‘GPIO_PWM_OP’ undeclared (first use in this function); did you mean ‘GPIO_PWM’?
198 | #define GPIO_PWM GPIO_PWM_OP
| ^~~~~~~~~~~
wiringPi.c:2451:85: note: in expansion of macro ‘GPIO_PWM’

and the installation fails on my orangepi5 plus

I also meet same issue in OrangePi zero , and use master branch is OK

OrangePi zero plus use master branch is OK

I change wiringPi\wiringPi.h line 122
https://github.com/orangepi-xunlong/wiringOP/blob/next/wiringPi/wiringPi.h
#define H3_PWM_BASE (0x01c21400)
to
#define H3_PWM_BASE (0x01C21000)
and it fixed

[drozdi70]

I recompiled and the same:
orangepi@orangepi5-plus:~/work/wiringOP$ sudo gpio readall
wiringPiSetup: mmap (PWM) failed: Operation not permitted

Sim, estou vendo a mesma mensagem em um Orange Pi PC2. Parece que algo mudou em uma atualização há apenas algumas semanas. Um problema de ramificação "próxima" versus ramificação "mestre"? Baixei e compilei a versão master e parece funcionar, pelo menos no modelo PC2 baseado em H5.

I tried downloading from this link but it doesn't work. The error appears: "fatal: unable to acess 'https://github.com/orange.pi-xunlong/wiringOP/archive/refs/heads/master.zip/': Could not resolve host: github.com

Just for anyone who wanted the commands to clone the master branch, this worked for me:
git clone --branch master https://github.com/orangepi-xunlong/wiringOP.git
cd wiringOP
./build clean
./build

And then of course, gpio readall to see pins.

I am using the OrangePi Lite.

仅适用于任何想要命令克隆主分支的人，这对我有用： git clone --branch master https://github.com/orangepi-xunlong/wiringOP.git cd wiringOP ./build clean ./build

然后当然，要看别针。gpio readall

我正在使用 OrangePi Lite。

I followed your approach and successfully solved the problem. Thanks

excellent, it works on H5Pi PC2

这个是因为后面更新把前面已经实现的功能搞出问题了而已——辨别版本更新的方法可能有所不同，而老版本已经无人维护。

可以checkout到老版本当年发布支持的那个提交，这样可以解决问题。如我的板子是lite1，H3芯片：

可以看到提交是2020年，提交号a846ffd8f5583516cd25c6b08e49fd9cc47728c4。

可见成功解决问题。

最新的版本PWM的基地址是01c21400，与H3芯片的数据手册对应。按照楼上的指导，我将基地址改为01c21000，orangpi one成功。说明H3数据手册的这个地址是错误的。同时，我回滚到github的历史版本，其中定义的PWM基地址确实是01c21000，可见初始的设置是正确的。回滚历史的方法也可以成功。
