3 years ago Thanks for the detailed bug report and diagnosis. I am stumped as to why it would work on x86 and not on Xavier with identical configuration. We have tested on Tx2 but don't have access to a Xavier.
@mithunvarma @PushyamiKaveti any ideas on what might be going on?
System Description Camera Name and Model: 2x Blackfly S (USB3, connected via Sync cable) Operating System: Ubuntu 18.04.5 Spinnaker Version: 2.2.0.48 ROS Version: Melodic
Computer details Processor: Nvidia AGX Xavier RAM: 32GB
Multiple Cameras Only How is the triggering setup? Master, Master/Slave, Default, see below
For USB 3.0 cameras: On same USB 3.0 bus or different buses? Same bus Is the USB 3.0 hub externally powered? Yes
Do the cameras work with SpinView? Yes
Describe the bug I can't acquire camera images when the camera is in master SpinView configuration on a Jetson AGX. Ros error is:
[FATAL]: Spinnaker: Failed waiting for EventData on NEW_BUFFER_DATA event. [-1011] Likely reason is that slaves are not triggered. Check GPIO cables
I have two Blackfly S cameras and have tested many configurations on a Jetson AGX and x86 laptop. On the x86 laptop, I can publish the two camera streams when in default Flir camera settings, publish the two camera streams when in Master/slave configuration, and publish one camera stream when in Master configuration.
On the Jetson AGX, I can build spinnaker_sdk_camera_driver, following the steps laid out in #89. Within SpinView, I can see the two camera stream when in default/default, two streams in master/slave, and single stream in master configuration. I can launch spinnaker_sdk_camera_driver and see the stream(s) when in default camera configuration(s). However, when I launch ros with the camera in master or master/slave configurations, ros errors out.
The above variations account for the related yaml files and such. Given the variations run on the x86 machine, I trust the configurations and connections are set appropriately. But I can't resolve why the ros launch errors on master configuration, especially given SpinView streams.
