Technical Description
Sensor/Camera: ZED X Mini
Driver: zedx-driver v1.3.2 (from GitHub)
Platform: NVIDIA Jetson Thor AGX
Environment: Ported to NVIDIA JetPack 7.0 (L4T R38.2.1)
Status: The device nodes /dev/video0 and /dev/video1 are successfully generated.
Issues
Question 1
When capturing a stream using the following command: v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1200,pixelformat=BA10 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=100 --stream-to=left.raw
I observed that after the SoC receives the MIPI data, only 20% of the frames are normal. The remaining 80% of frames trigger CRC errors. NVIDIA suggested checking the values for pix_clk_hz, line_length, and embedded_metadata_height. Could you please provide the recommended range or calculation method for these parameters?
Question 2
While /dev/video0 can output a stream (despite the CRC errors), /dev/video1 fails to output any data. When using the same v4l2-ctl command to capture from video1, the SoC MIPI interface does not receive any data flow at all. What are the recommended steps to troubleshoot why the MIPI data is not reaching the SoC for this specific node?
Hi @ArcherZ
Welcome to the StereoLabs community.
How have you connected the ZED X Mini camera to an NVIDIA Jetson Thor AGX?
Normally, it’s not possible to connect a GMSL2 capture card to it.
Thanks for the reply. I am using a third-party Thor AGX carrier board connected to a GMSL2 deserializer board (MAX96712) via MIPI. Currently, I am using GMSL Port A to connect the ZED X Mini.
hi，Is there any progress？
For third-party carrier boards, you need a custom driver.
What is the model of the carrier board that you are using?
T5000 + P3834, When will the driver for ZEDX compatible with JP7.0 be released?
