Segmentation fault using an Ajazz AKP153

Hi I have an AjazAKP153 and when I open opendeck with the device connected it closes immediately. I'm on Debian 12 using X11 not wayland, although I've also tried the windows version and it closes the same way. This is the only error it returns: (opendeck:21611): WARNING : 19:39:59.050: webkit_settings_set_enable_offline_web_application_cache is deprecated and does nothing. [2024-10-01][17:39:59][DEBUG][tiny_http] Server listening on 0.0.0.0:57118 [2024-10-01][17:39:59][DEBUG][tiny_http] Running accept thread [2024-10-01][17:39:59][DEBUG][opendeck::events] Registered plugin com.amansprojects.starterpack.sdPlugin Violación de segmento (`core' generado) There is nothing in the log that indicates what the error could be. Is it possible that I missed something? or that I'm missing something to install? I would appreciate any help.

@zyp and @Fl1tch seem to be both having the same issue. I would recommend one of you opening an issue on the GitHub repo of elgato-streamdeck and ping @ZCube on it. @GodinRaider @zyp @Fl1tch @was could you all try these steps to run the example code of the library that OpenDeck uses? git clone https://github.com/streamduck-org/elgato-streamdeck.git cd elgato-streamdeck/examples/simple cargo run

I do not know what I did. But I installed rustup-init and executed these three commands in the terminal. Here is the answer to the last one. What else do I need to do to make something work? 🙂

ninjadev64•3mo ago

ah it seems they've done it a bit differently try cd examples/simple cargo run

does anything happen? as in, anything on your device or when you press a button?

GodinRaider•3mo ago

The screen saver with the Ajazz logo is still displayed. If you press any button, the screens go off. If you press again, the screensaver appears. In the OpenDeck, it also writes "No devices detected"

ninjadev64•3mo ago

You have the AKP153R right?

GodinRaider•3mo ago

Yeah.

ninjadev64•3mo ago

Alright, so that confirms it's separate device with different firmware. One more thing: what are the vendor and product IDs of your device? I'm not sure how to find that on Windows which you seem to be on but you can Google it

GodinRaider•3mo ago

VID_0300&PID_1020 Isn't that it?

ninjadev64•3mo ago

Try changing lines 26 and 29 of info.rs to those and see if it works? Make sure to remove the 0x that's there already so they're not interpreted as hexadecimal

GodinRaider•3mo ago

/// Vendor ID of Ajazz Stream Deck
pub const AJAZZ_VENDOR_ID: u16 = 0300;

/// Product ID of Ajazz Stream Deck AK153
pub const PID_AJAZZ_AKP153: u16 = 1020;

/// Vendor ID of Ajazz Stream Deck
pub const AJAZZ_VENDOR_ID: u16 = 0300;

Like this? I saved the file, then executed the "cargo run" command in examples/simple again. This is the result that came out

No changes. I see that in the code above it is suggested to run with the command "cargo fix --bin "simple"". Is it worth trying to do it?

That's what happened after I started the command accepting the changes. The running/restarted OpenDeck was not affected. The device itself behaves the same way with the screensaver

ninjadev64•3mo ago

The changes are irrelevant and OpenDeck will not be modified by this, the whole of OpenDeck has to be recompiled for it to be modified, we're only testing the example of the library. I guess the only thing remaining that you could try is putting the 0x back in front of the numbers, but if that doesn't work then your device is different and would need more work and reverse engineering to implement support for.

This is when I inserted 0x0300 and 0x1020. And what showed without errors last time is not what we need? Or should there be a different result on the command line?

ninjadev64•3mo ago

Yeah, I was getting you to try this to see if the AKP153R was compatible using the same code, but it is a different device and will need to be implemented into the library by someone with reverse engineering skills. (which I presume you don't have as you don't seem to be a programmer) @GodinRaider someone is working on supporting the AKP153E, which looks more similar to the AKP153R that you have. Once those changes are in, I'll let you know the steps to try it again with the changes to see if that works

GodinRaider•3mo ago

Great! I'll be looking forward to it!

ninjadev64•2mo ago

@everyone OpenDeck v2.2.1 has some updates and fixes for Ajazz devices, notably support for the AKP153E device @GodinRaider you could try this again, delete the elgato-streamdeck folder first, and make sure to change the PID_AJAZZ_AKP153E to 0x1020 to match your device I don't have the highest hopes of it working but it's worth a try

Its after I reupload elgato-streamdeck and change PID

Hmm ok, seems this still applies unfortunately ^
