Hello,
I’m trying to use ZED X camera on ZED Box Orin NX 16GB. When I open ZED Explorer, it starts streaming video from it, which stops after about 10-30, showing this error in the terminal after few more seconds:
(Argus) Error Timeout: (propagating from src/rpc/socket/client/ClientSocketManager.cpp, function send(), line 137)
(Argus) Error Timeout: (propagating from src/rpc/socket/client/SocketClientDispatch.cpp, function dispatch(), line 91)
Restarting ZED Explorer doesn’t restart the streaming - to do so, I need to restart both nvargus-daemon and zed_x_daemon, but after that the whole process repeats - streams freeze after 10-30s. Problem is not limited to ZED Explorer - nearly the same issues happen with ROS2 wrapper - I’m able to start it and receive data for some time, then it stops.
There is a lot of happening in the logs:
- dmesg show some I2C issues related to ZED X: Failed to register i2c client eeprom_zedxone_uhd at 0x54 (-16)
- journalctl shows hundreds of nvargus-daemon errors and warnings
I’ve also tried updating the ZED X drivers (currently, I’m using 1.2.0-LI-MAX96712-all-ZEDBOX-L4T36.3.0), but it didn’t help.
Just to mention - I have the second set of hardware (ZED X + ZED Box), on which everything works without similar issues.
ZED_Diagnostic dmesg output:
