Support for OrangePi 5/Plus

[Son-kun]

Hi, is there any plan to support other device than RPi?
I'm specifically asking about Orange Pi 5 Plus.
Currently RPi is behind in terms of computing power, so I'm forced to move to Orange and I'm trying to use GPIO on this SBC...

[taartspi]

No plans to support any SBC other than RPI. The Pi4j V2 statement is: [(https://pi4j.com/about/new-in-v2/)] v2

The following features have been removed from the Pi4J library:
Other Platforms – Other platforms such as Odroid, BananaPi, NanoPi, OrangePi, etc. have been removed and will no longer be supported.

[FDelporte]

Indeed, there are no plans. But... ;-)

As you can see on the architecture diagram, https://pi4j.com/architecture/, the design with modules does allow the creation of a package for other platforms. Only Raspberry Pi was kept as the maintenance and testing grew exponentially with each platform, and we don't have enough "power" to handle this. Of course, if someone would stand up to take up this role for a specific platform, that decision can be reconsidered.

[sbeeker]

I wanted to "attempt" to create two new "matrix" images, and wanted to know if it is okay.

1. Make a I2C version of the CrowPi basically for Coder Dojo kids.
2. Put a MAster /Slave communications concept between Hardware and Pi4J libraries I guess. Add communications effectively to distribute the devices. Example of maybe mosquito pub / sub transport between controllers and slaves for the device.

Perhaps in private email discuss.

I would work in own repos and if you see anything you like can take it back. Should be easy merge at least for the matrix build part.

Learned so much today reading all these projects. Quite impressive work!

[FDelporte]

Hi, any idea to use at CoderDojo is a good idea :-)
And, of course, please do fork or experiment in your own repos and keep us in the loop! Even if it isn't something to merge in the Pi4J repos, we can at least write about it on https://pi4j.com/featured-projects/, the blog, and/or our social media.
Have fun experimenting!!!

I checked the source code to try and support the RK3588, (different board from the OPI 5 Plus but the same microcontroller). I had high hopes that the plugin system would make this possible.

It's a great idea, but unfortunately, the plugin system alone isn't sufficient. The core library would need substantial modifications because many elements, like BoardInfo, BoardInfoHelper, and BoardModel, are heavily dependent on non-inheritable or non-extendable classes and enums.

For example, GPIOD library could be re-used "as-is" on the RK3588 but there are multiple checks on the BoardModel (that cannot be extanded) and thus prevent the library from loading

[oliviercoma]

Hello @FDelporte,
Thanks for your response.

The private constructor of BoardInfoHelper tries to detect the board type and creates a BoardInfo. But currently, only values from enum BoardModel can be discovered with the implemented mechanism (and thus only Raspberry PIs).

getBoardName() actually works and returns correct value (Radxa ROCK 5A) in my case, but boardModel is then returned as UNKNOWN as there is no enum value for it.

I thought I could live with this, as this does not make the library crash or stop, but then GPIODContext does not work due to:

if (BoardInfoHelper.current().getBoardModel() == BoardModel.UNKNOWN) {
    logger.warn("Can't initialize GpioD context, board model is unknown");
    return;
}

Note that there are other occurences of this check (e.g. in NativeLibraryLoader.loadLibraryFromClasspath)

It could be good to have plugins that can discover board models and genericze BoardModel (and related classes Soc, Cpu), to make it an interface. HeaderVersion and others device related variables could be plugin specific in the implementation (i.e. RaspberryPiBoardModel interface extending BoardModel interface)

[FDelporte]

For multiple reasons, I wanted to try RPi-alternatives for some time now, but never got started with it. So time for the next step ;-) I just ordered an Orange Pi 5 with RK3588 and I think I have somewhere an older RK-board. I'll try to do some experiments asap with these and extend the BoardInfoHelper. It would be nice to learn how Pi4J can be used on other boards...

[oliviercoma]

Further investigation:

I've set the BoardModel as MODEL_5_B using reflection and made some progress.
I've found that GpioDContext makes the assumption that:

• All usable Gpio lines are on the same GpioChip
• The GpioChip of intereset is labelled "pinctrl".

For the RK3588S:

• There is not just one gpiochip of interest (Gpio lines are spread out on multiple cpiochips)
• The Gpiochips are labelled "gpio0", "gpio1", "gpio2", "gpio3", "rk806-gpio"

To genericize it, I see multiple solutions:

• Add argument to getOrOpenLine so that gpiochip can be passed as well
• Let plugins the abaility to define some kind of mapping
• Abstract away the concept anb use named lines e.g. from my Radxa 5A:

pi@pi-desktop:~$ sudo gpioinfo
gpiochip0 - 32 lines:
        line   0:      unnamed       unused   input  active-high
        line   1:      unnamed       unused   input  active-high
        line   2:      unnamed       unused   input  active-high
        line   3:      unnamed       unused   input  active-high
        line   4:      unnamed       unused   input  active-high
        line   5:      unnamed       unused   input  active-high
        line   6:      unnamed       unused   input  active-high
        line   7:      unnamed  "interrupt"   input  active-high [used]
        line   8:      unnamed       unused   input  active-high
        line   9:      unnamed       unused   input  active-high
        line  10:      unnamed       unused   input  active-high
        line  11:      unnamed       unused   input  active-high
        line  12:      unnamed       unused   input  active-high
        line  13:      "PIN_8"       unused   input  active-high
        line  14:     "PIN_10"       unused   input  active-high
        line  15:      unnamed       unused   input  active-high
        line  16:      unnamed       unused   input  active-high

I don't know if it's a possibility with Raspberry Pis (names are defined in Linux device tree configuration files), but it would be my preferred solution

[AlexR1973]

Hello guys!
Did somebody get a positive result with PI4J working on Orange Pi? Just got "Orange Pi 3 zero" board from my friend and find out that PI4J is not supported on boards other than Raspberry Pi :( Maybe we have unofficial support of this board?

[FDelporte]

Regarding multiple chips in GpioDContext: in V3.0.0 it will be possible to set the chip name, so you can create a context for a specific chip or create multiples. See https://www.pi4j.com/documentation/providers/gpiod/#specifying-the-gpio-chip.

While we don't plan to add Orange Pi (or other boards) support with the current core team, I think it would be feasible to add a way to extend the board detection with a "forced type" so you can instruct the library to load the plugins for e.g. GpioD. Let me look into that as soon as possible...

@AlexR1973 @Son-kun @oliviercoma , can you cooperate on this to test if a SNAPSHOT version is available?

[FDelporte]

I created a DRAFT pull request with a proposal on how the board model can be forced:
#453

Specifically this new method:
https://github.com/Pi4J/pi4j/pull/453/files#diff-5db2d4a8f0b493c7098a682c53d87209be8b0a5ccf9257dc692047b909794061R54

And two additional generic board models:
https://github.com/Pi4J/pi4j/pull/453/files#diff-47b61c62427d74f6a4eb8ca274b39df27de26250b4f47094e140999001e549ceR317

You would use it for setting the board model before creating the Pi4J context:

# With default GpioD chip
BoardInfoHelper.current().setBoardModel(BoardModel.GENERIC);
var pi4j = Pi4J.newAutoContext();

# Or if you want to use a specific chip name
BoardInfoHelper.current().setBoardModel(BoardModel.GENERIC);
var pi4j = Pi4J.newContextBuilder()
    .add(GpioDDigitalInputProvider.newInstance())
    .setGpioChipName("gpiochip2")
    .build();

@AlexR1973 @Son-kun @oliviercoma WDYT?

[AlexR1973]

Thanks a lot for your help guys!
First of all, I have to prepare the environment for tests: install VNC, Java, SAMBA, etc. After that I will update my project to use PI4J version 3.0 and create some simple tests to work with GPIO, I2C, 1Wire. I will inform you about the progress in this thread.
BTW, did you see GPIO from DigitalSmile (https://github.com/DigitalSmile/gpio)? I think PI4J should be moved to Java 22 ASAP even if it's not LTSC. Removing JNI will allow PI4J work in different environment. For example, Tomcat has its own class loader and prevents a correct work of PI4J. I think without JNI we can work under Tomcat without any issues.

[FDelporte]

22 is no LTS so that's why we first made the jump to Java 21. But 25 in September is LTS, so we can already start preparing for it and use JNI... @eitch has already done some first tests.

More info: https://www.pi4j.com/blog/2025/20250211-welcome-java-21/

[FDelporte]

Please use 3.0.1 to test this

[AlexR1973]

Good day my friends!
I have spent hours to run a simple example on Orange Pi zero 3. But no luck at all :(
I have Java-24 downloaded from https://bell-sw.com/pages/downloads/#jdk-24 and installed on Orange Pi.
Also, I have Java 24 for IntelliJ Idea project.

In main method I have only 4 lines of code as you advised:

    final var console = new Console();

    BoardInfoHelper.current().setBoardModel(BoardModel.GENERIC);

    var pi4j = Pi4J.newContextBuilder()
                   .add(GpioDDigitalInputProvider.newInstance())
                   .setGpioChipName("gpiochip0")
                   .build();

    console.println("Hello world!");

===

My module-info.java has next lines of code:
module OrangePiGPIO
{
requires com.pi4j;
requires com.pi4j.library.pigpio;
requires com.pi4j.plugin.gpiod;
exports com.hds;
}

Finally, after few hours of experiments I was able to compile and run it on Orange Pi zero 3 but with next exception:

SLF4J(W): No SLF4J providers were found.
SLF4J(W): Defaulting to no-operation (NOP) logger implementation

Looks like BoardCodeReader class not found. When I try to include com.pi4j.boardinfo into module-info.java - Intellij can't see it :( :

requires com.pi4j.boardinfo; // Can't see the module, but it is present in the lib folder

My run.sh script is simple:
sudo java --module-path ./lib -jar ./lib/OrangePiGPIO.jar

lib folder contains the next set of Java libraries:
jna-5.15.0.jar
jsch-0.1.55.jar
OrangePiGPIO.jar

pi4j-plugin-linuxfs-3.0.1.jar
pi4j-plugin-raspberrypi-3.0.1.jar
slf4j-api-2.0.12.jar

What am I missing? I am stuck and continue at this point. Spent at least 5-6 hours with no luck :(

[FDelporte]

is module-info.java really needed?
if so, please also add requires com.pi4j.plugin.raspberrypi;

Can you also add the PrintInfo lines as seen here:
https://github.com/Pi4J/pi4j-example-fatjar/blob/main/src/main/java/com/pi4j/example/MinimalExample.java#L101

PrintInfo.printLoadedPlatforms(console, pi4j);
PrintInfo.printDefaultPlatform(console, pi4j);
PrintInfo.printProviders(console, pi4j);

Hoping you could get some output like this example:
https://www.pi4j.com/getting-started/minimal-example-application-fatjar/#building-and-running

[FDelporte]

Or maybe even easier, use a single test file approach with JBang as described here:
https://www.pi4j.com/examples/jbang/jbang_minimal_example/

[AlexR1973]

I added slf4j-simple to MAVEN pom.xml file and now get another exception:

I almost ready to give up :( My project was running on Raspberry Pi 2 rev. B for hours without exceptions. On Orange Pi I can't even pass the context initialization in 5 lines of code example. I know that only Raspberry boards are supported, but why Java can't see classes from JAR files?

[AlexR1973]

@FDelporte looks like I have the problem in the Java 24.
In the other project I have the same exception - NoClassDefFoundError. But when I change places of 2 blocks of code - IT DISAPPEARS! I have never seen this before. Going to find another version of Java 23 or 24 from different vendor and try it.
Now I have bellsoft-jdk24+37-linux-aarch64-full.deb and looks like it has some issues with class loading - maybe my SD card to fast/slow or it is incompatible with Raspi OS I am using. I will continue my investigation with different JDKs.

[AlexR1973]

This is definitely JDK error. Same set of JAR files under Java 24 and Java 25 give me NoClassDefFoundError exception:
Exception in thread "main" java.lang.NoClassDefFoundError: com.pi4j.registry.impl.DefaultRuntimeRegistry

JDK 23.0.2 gives another error (see below). Maybe NoClassDefFoundError related to the one below. Will continue my investigations with different versions of JDK.

Anyway, thanks for your help and time Frank!
I have Orange Pi zero 3 with RaspiOS for Orange Pi installed. I got it here:
https://github.com/leeboby/raspberry-pi-os-images/releases

It looks the same as Raspberry Pi OS I use on my Pi 2.0 rev B. According to the documentation RaspiOS for Orange Pi supports GPIO, I2C, 1Wire, etc.
