Could you check the v4l2-ctl command after change the connector.
I just typed this command " v4l2-ctl --stream-mmap --set-ctrl bypass_mode=0" and terminal response nothing as follow.
What’s the kernel message after this command?
it shows nothing, just cursor keep blanking
I mean the kernel message by dmesg
It’s very weird !
Even no camera is connected to Jetson, dmesg has some imx219 related logs like this.
It’s same when camera module is out or order.
jetson@jetson-desktop:~$ dmesg | grep imx219 [ 1.264319] imx219 6-0010: tegracam sensor driver:imx219_v2.0.6 [ 1.287658] imx219 6-0010: imx219_board_setup: error during i2c read probe (-121) [ 1.287685] imx219 6-0010: board setup failed [ 1.287748] imx219: probe of 6-0010 failed with error -121 jetson@jetson-desktop:~$ cat /etc/nv_tegra_release # R32 (release), REVISION: 4.3, GCID: 21589087, BOARD: t210ref, EABI: aarch64, DATE: Fri Jun 26 04:38:25 UTC 2020
I reflashed the jetson nano and have jetson inferenced installed. I then followed the instructions on jetson-inference/docs/ aux-streaming.md and still cannot get camera turned on?
I typed video-viewer csi://0
for CAM1 slot jetson nano crashed and reboot itself
for CAM2 slot terminal return the message of view-viewer: failed to capture video frame
[gst_mini_object_set_qdata: assertion ‘object != NULL’ failed Eror]
Hi @wi072815, are you sure the camera’s ribbon cable is installed into the header port in the correct orientation? The contacts of the cable should face inwards towards the module like here:
Also, try seeing if
nvgstcapture-1.0program can view the camera stream.
Sorry for keep posting!
I ran video-viewer from jetson-inference with command video-viewer csi://0
and I get this message
I am an beginner I recently purchased Jetson Nano 4GB kit and Imx 219-120 have similar Error coming tried to swap the ports and re flashed but still the same during booting there is this message (imx219_board_setup: error during i2c read probe (-121)).
Would you try this simple example?
BTW, you’d better change the camera module.
I recently got DoA.
