at debug window I got this:

09:25:01: Debugging starts
&"warning: GDB: Failed to set controlling terminal: \343\203\207\343\203\220\343\202\244\343\202\271\343\201\253\345\257\276\343\201\231\343\202\213\344\270\215\351\201\251\345\210\207\343\201\252ioctl\343\201\247\343\201\231\n"

It doesn't have any deviecs Avaliable.

That means that you has did not installed the peack-can plugin in your Raspi. Maybe it is in the Raspi repository, also maybe something else. You can search for this shared library in your Raspi file system where the Qt installed.

It is a question to the Raspi maintainers.

kuzulis

Besides, to use the PEAKCAN you need to install to the Raspi the PEAK-CAN vendor drivers and specific shared libraries downloaded from the PEAK-CAN WEB site. Are you sure that you have all these requirements? Read the documentation at first: https://doc.qt.io/qt-6/qtserialbus-peakcan-overview.html

UPD: You can use the socket-can plugin with the PEAK-CAN adapters, that does work by default. The PEAK-CAN adapter is detected in Linux as usual socket-can device (AFAIK).

I already Installed Peakcan driver before. but I had wrote the below code and didn't have any return or deivces showed

const QStringList plugins = QCanBus::instance()->plugins();

for (auto plugin : plugins) {
    QString errorString;
    const QList<QCanBusDeviceInfo> devices = 
          QCanBus::instance()->availableDevices(
                plugin, &errorString);
    if (!errorString.isEmpty())
        qDebug() << plugin << errorString;
    for (auto device : devices)
        qDebug() << plugin << device.name();
}

@y-exars said in No such plugin:"peakcan" on Raspi:

const QStringList plugins = QCanBus::instance()->plugins();

does plugins contains peakcan ?

@kuzulis

program did not run into

for (auto plugin : plugins)

while debug plugin is show 0

kuzulis

Well, it means that your Raspi has not any qtserialbus plugins installed. Maybe they are in the different packages of Raspi repository. You need to install them.

@kuzulis

but I already installed qtserialbus by using

sudo apt-get install libqt5serialbus5-dev

this one, doesn't install qtserialbus plugins ??
