Noob here. Basically, I am trying to run the IMX477 camera via CSI slot 0 and some LED strip WS2812B via SPI1. My Problem is, as already discussed and solved here , that camera and LEDs together(!) are not working. I tried following the solution but I encouter several problems there, so hopefully s…

Hi yoghurt , For r32.6.1, please use below steps to enable imx477: Follow the commands below to Configure IMX477: - sudo /opt/nvidia/jetson-io/jetson-io.py - Select "Configure Jetson Nano CSI Connector" - Select "Configure for compatible hardware" - Select "Camera IMX477 Dual" - Sele…

Hi @carolyuu , thanks so much for you help! With your instructions, I managed to configure both, the imx477 camera and SPI1: home@jetson-nano:~$ ls /dev/video* /dev/video0 home@jetson-nano:~$ ls /dev/spi* /dev/spidev0.0 /dev/spidev0.1 /dev/spidev1.0 /dev/spidev1.1 However, I now get this err…

Looks like the devname in tegra-camera-platform{} didn’t match the driver name. Have dump dtb to confirm it. The devname need the same with v4l2-ctl --list-device like below, devname need the same with “ov5693 30-0036” nvidia@nvidia-desktop:~$ v4l2-ctl --list-device vi-output, ov5693 30-0036 (pla…

Ok, here is the output: home@jetson-nano:~$ v4l2-ctl --list-device vi-output, imx477 8-001a (platform:54080000.vi:4): /dev/video0

Please dump the device tree to confirm. sudo dtc -I fs -O dts -o extracted_proc.dts /proc/device-tree

Ok, here is the whole device tree dump: $ sudo dtc -I fs -O dts -o extracted_proc.dts /proc/device-tree extracted_proc.dts: Warning (unit_address_vs_reg): Node /reserved-memory/fb0_carveout has a reg or ranges property, but no unit name extracted_proc.dts: Warning (unit_address_vs_reg): Node /rese…

Check the context in tegra-camera-platform{} in extracted_proc.dts

tegra-camera-platform { isp_bw_margin_pct = <0x19>; compatible = "nvidia, tegra-camera-platform"; max_pixel_rate = <0x3a980>; num_csi_lanes = <0x4>; vi_peak_byte_per_pixel = <0x2>; max_lane_speed = <0x16e360>; phandle = <0x12a>; vi_…

The devname didn’t match. Maybe change to another port to try. [image] yoghurt: devname = "imx477 7-001a"

Thanks, I double checked the cables and tried both cam0 and cam1 ports on the Jetson Nano. As expected, when the camera is on cam0 I get: home@jetson-nano:~$ v4l2-ctl --list-devices vi-output, imx477 7-001a (platform:54080000.vi:0): /dev/video0 Instead of imx477 8-001a. Unfortunately, the I…

The devname didn’t match.
Maybe change to another port to try.
