Hi all, I’m running the TX2 on a Leopard Imaging LI-TX-CB1 carrier board with a Leopard Imaging LI-IMX185 MIPI (v1.1). After reading a lot of threads without having success, I followed instructions at the end of this thread (by Leopard) and installed L4T 28.1. [https://devtalk.nvidia.com/default/topic/999524/jetson-tx1/how-to-get-video-stream-from-imx185-mipi-leopard-/](https://devtalk.nvidia.com/default/topic/999524/jetson-tx1/how-to-get-video-stream-from-imx185-mipi-leopard-/) No problems with USB and fan connected at j15 at this moment. The camera finally appears to be recognized, but when I run ```auto nvgstcapture-1.0 ``` or ```auto gst-launch-1.0 nvcamerasrc ! autovideosink ``` I do get output, but it’s no more than a pure green square. It appears no actual data is received, but no error is present. Output from the first command (nvgstcapture-1.0) is as follows: ```auto nvidia@tegra-ubuntu:~$ nvgstcapture-1.0 Encoder null, cannot set bitrate!

Please make sure you flash the R28.1 OS image to the TX2 SOM. ---

Hi Simon, Thanks for your reply! I’ve followed the instructions in the given link, but when I execute step 10. Open a terminal and do "nvgstcapture-1.0”. You will get live video output. I still get the green output. I will try to continue with the Argus and kernel steps to see if this makes any difference in output, but the instructions suggest I would already have a successful stream with nvgstcapture-1.0 ---

Hi TechnoM, Please make sure you plug the camera to J1 of the carrier board. If you do “ls /dev”, can you see video0 ~ video2 under /dev ? When did you buy this camera kit? Did it work before or never worked? ---

Hi Simon, I can confirm the camera is plugged into J1 of the camera board. ls /dev shows three video occurrences: ```auto nvidia@tegra-ubuntu:~$ ls /dev/ | grep video* video0 video1 video2 ``` We purchased the kit last month and this is our initial attempt to get it working. We are using the TX2 from the development kit. I’ve tried using Argus as described in the instructions, but the argus application crashes. The gstreamer command in the instructions also fails to create a pipeline. Edit: could it be I need to override some settings (bitrate or resolution) with the IMX185, i.e. the defaults may not be correct for nvgstcapture-1.0? ---

Hi TechnoM, How many IMX185 cameras do you have? Could you try a second camera to see if it works? Have you flashed the TX2 SOM with R28.1 TX2 OS image which can be downloaded from our driver guide? ---

Hi Simon, We only have one IMX185 camera to work with. Is it possible to verify it is recognized properly (e.g. dmesg)? I have flashed the TX2 with the OS image supplied by your link in reply #2, which is R28.1 edit: the output of dmesg after startup is: ```auto nvidia@tegra-ubuntu:~$ dmesg | grep imx185 [2.639367] imx185 30-001a: [IMX185]: probing v4l2 sensor at addr 0x1a.

I’ve got it working by **NOT** following in the instructions for “slave mode” (see: [Dropbox - File Deleted](https://www.dropbox.com/sh/cksco0qwgsyupt0/AAB9XhC2E0sIi1unUe6JbDAHa?dl=0&preview=Screenshot+2018-08-06+14.28.46.png) ) I changed the dipswitch to “ON” and got image with ```auto nvgstcapture-1.0 ``` Simon, can you tell me if the documentation about slave mode is wrong or is the camera now in “master” mode? What is slave mode anyway? ---

Hi TechnoM, Great to know it works. Yes, the IMX185 camera with LI-TX1-CB only support master mode. Our another carrier board LI-TX1-CB-6CAM supports IMX185 camera in slave mode since this 6CAM carrier board includes a FPGA which can generate trigger signals to trigger the cameras. ---
