When connecting the ZED Link Mono to the Jetson Orin Nano, can it achieve a speed of 6 Gbps? According to the official connection instructions, the ZED Link Mono is connected to the J20 port on the Jetson Orin Nano. However, based on the Jetson Orin Nano reference design, the J20 interface only supports CSI x2, meaning it can only reach a maximum of 5 Gbps. This contradicts the ZED Link Mono documentation, which states support for 6 Gbps. Why can’t it be connected to the J21 port on the Jetson Orin Nano, which supports x4 lanes? When attempting to connect to J21, the camera is not recognized properly. After analyzing the device tree, it was found that the lanes width is set to 2 in the device tree. If I want to use 4 lanes, could you provide the corresponding device tree modification documentation or guidance?
The J21 utilizes the MIPI CSI-2 and CSI-3 of Jetson Orin Nano, which can support 4 lanes. The current driver being used is stereolabs-zedlink-mono_1.3.1-SL-MAX9296-all-L4T36.4.0_arm64.deb, and the JetPack version is the latest 6.2. My question is, does this driver support the CSI-2和CSI-3 on the J21 pins? Currently, the driver can be installed, and the camera is detected, but the camera’s serial number is 0, which prevents normal use of the camera. I suspect this issue is caused by the device tree configuration of the driver.
Additionally, when using a 2-lane configuration, can the GMSL2 rate reach 6 Gbps? How can I configure it to achieve this rate? I’m not entirely sure what “Please note that using 4 lanes won’t solve this issue” means. Could you elaborate on this? Thank you!
