I have two Jetson Nanos (B01) that won’t recognize a Raspberry Pi Camera (v2.1)(both items were from SparkFun). I’ve tried two different v2.1 cameras in both slots on both Nano units.
I’m facing the cable blue side out, silver side towards the inside. I’ve confirmed visually that the silver contacts are aligning. I’ve tried powering the unit via the USB port and the barrel jack.
Any help at all troubleshooting will definitely be appreciated. One of the other threads suggested a hardware issue that was fixed via RMA.
The dmesg output shows:
i2c-mux-gpio cam_i2cmux: 2 port mux on Tegra I2C adapter adapter
We haven’t really tested the Pi cameras with the Jetson Nano. We primary support the [Leopard Imaging Camera as that is the hardware Nvidia recommended; it is also natively supported and has been tested to be compatible with the Jetson Nano.
However, there are instructions on using a Pi camera. Could you direct me to what you are following or give me more exact details about what script or code you are running to get that error message. Otherwise, if you aren’t following any specific instructions, this tutorial is referenced multiple times in the top google search for using the Pi camera with the Jetson Nano: [https://www.jetsonhacks.com/2019/04/02/jetson-nano-raspberry-pi-camera/.
Additionally, have you checked out the [Nvidia Forums. There seem to be several threads on the topic:
Thanks, I had followed that tutorial (and a few others).
I’ve posted on the Nvidia forums. The Pi v2.1 is listed as a supported camera on their wiki (version confirmed). (Note: the Pi camera comes up as suggested on the Sparkfun site when viewing the Jetson Nano kit). I would order a Leopard, but it’s backordered everywhere - any other camera suggestions? I also looked for a USB camera, but those are also sold out due to corona.
My best guess is either you have a connection or hardware issue.
- Is your camera cable creased? That is a common hardware issue.
- Otherwise, the issue is with either the camera or Jeston board. Unfortunately, it is pretty hard to diagnose them without additional hardware. These are the simplest options that I can come up with:
- Would you happen to have a Raspberry Pi that you can test the Pi Camera with? If so, I would double check that the camera is working on another device.
- Unfortunately, my technical knowledge for testing the Jetson hardware is limited and I may have to direct you to their forums eventually. However, my best idea for testing the camera interface is to check that the I2C bus is working. Do you have any I2C devices that you might be able to check the Jestson with?
I bought a Pi 4 and played around with the cameras. At first neither worked, but after I reseated the ribbons on the camera side, one of them began to work. I took the working ribbon and tried on the other camera, but it didn’t work there. So, I took the working camera over to the Jetson and it worked there also. I thought I was going crazy there for a while.
So, I need to RMA one of the cameras back and get a replacement.
Sorry, to hear that you received a malfunctioning camera, but I’m glad you got it figured out. I’ll forward this to one of our support team members so they can reach out to you for an RMA.
