Thank you all for helping debugging on this issue. I just saw this issue. Let me check if I can help.
I will test this issue on my side to see if this issue can re-produced stable.
I don’t think this issue is same with post " Decreased Framerate - Jetson Xavier Board - 4K video capture with (6) cameras". Since in that case. Customer using a special resolution which not defined in firmware to recording video. That may require Xavier to cost extra resource for resize. We believe this is the reason for frame drop at that case. When we test with the default resolution (even the full resolution). The frame rate can keep up than 28fps.
This driver using 4 MIPI lane setting in MAX9296 chip. I need to confirm with our team how we config the 4 MIPI lane setting. Since we use 2 x 1.2G or 4 x 700M for MAX9296 setting before (on other platform). If this driver using 4 x 700M setting. Then the bandwidth for each camera (1.4G/camera) is actually less than 2 x 1.2G (setting which in the other post Honey_Patouceul mentioned).
I will actual test here and check with our team to make sure the bandwidth is enough. We will try to address the issue and keep update here.
Let me give You more information about the environment.
I’m using Leopard Imaging IMX390 cameras, Jetson AXG Cavier Dev kit with GMSL camera board JCB004 for 8 cameras.
Jetpack 4.3 with drivers for GMSL camera board.
I will expect Your test results. Thank You!
Hi Kevin! I’ve tried this manual but the cameras did not start.
I got to point 7 of “Setup Procedure” but “nvgstcapture-1.0” cmd write me “No cameras available”. I can not find cameras into /dev directory too.
If you can’t find any video device. Then you should get some wrong operation or error when you flash the device tree (dtb file) which is step 2 & 3 in the instruction. Please make sure you can flash the device tree correctly.
BTW. Do you use our adapter board? You need to use our adapter board & camera to make this driver work.
