Hi,
My Zedx camera always have the initialization problem, after running on ROS1 driver for around 10 minutes, it generates:

Log file from dmesg:
dmesg_3.log (17.5 KB)

Zed SDK version:
ZED_SDK_Tegra_L4T35.3_v4.1.2
This problem happened after updating the ZED SDK.

Please help me what happened here, thank you.

Please update the ZED X Driver to the latest v1.0.5. You are using the very old version 0.5.4.
Please remove the old driver before installing the new one: sudo dpkg -r stereolabs-zedx

Hi,
Thanks for the quick reply.
After updating the ZED X Driver to the [latest v1.0.5], dmeg log file looks like:
dmesg_4.log (27.6 KB)
Is there any errors still existing?

4

No, your camera is correctly detected and initialized.

Can you open it with ZED Explorer and ZED Depth Viewer?

5

Hi,
unfortunately, the ROS node still generates the same initialization problem. ZED Explorer and ZED Depth Viewer work with no problems.
Here is the dmesg file record after the initialization problem happened.
dmesg_2.log (29.6 KB)

Hi, new error appears after reinstall ros wrapper package:

If you stop the node not correctly the ZED X Driver can remain in pending status for ~20 seconds.
You can manually force a reset by using the commands
sudo service zed_x_daemon restart
and
sudo service nvargus-daemon restart

Hi, I found that another Ublox driver might cause “Connection reset by peer”, Ublox created a socket to abstract RTK GPS data (port 3503):

if (pm.input_rtcm)
        {
            // socket.reset(new SocketHandler("localhost", pm.rtcm_tcp_port));
            // socket->addCallback(std::bind(&SerialHandler::writeRaw, serial.get(), 
            //     std::placeholders::_1, std::placeholders::_2, pm.IO_TIMEOUT_MS));
            // socket->startRead();
            if (!socket || !socket->isConnected()) {
                socket.reset(new SocketHandler("localhost", pm.rtcm_tcp_port));
                socket->addCallback(std::bind(&SerialHandler::writeRaw, serial.get(),
                                            std::placeholders::_1, std::placeholders::_2, pm.IO_TIMEOUT_MS));
                socket->startRead();
            }
        }

From observation, each time ublox rosnode starts, zedx will generates errors.
Is there any solution to avoid conflictions, sorry I’m not familiar with TCP communication. I just checked all ports used and didn’t see any overlapped ports.

Thank you.

Hey I tried doing
sudo service zed_x_daemon restart
and
sudo service nvargus-daemon restart

but still the error persists

Hey @Myzhar, can you say a solution to the above issue

Hi @maheshreddy
To assist you better, we need additional information regarding your device’s condition and system setup.

Please open a terminal console (Ctrl+Alt+t) and run these commands:

  • sudo ZED_Diagnostic --dmesg
  • ZED_Diagnostic -c

After executing the commands, kindly send me the files dmesg.log and ZED_Diagnostic_Results.json located in the folder where the commands were run.
