To the command “ls /dev/video0”
I get “/dev/video0” no matter if the camera is connected or not.
To the command “v4l2-ctl --stream-mmap --stream-count=-1 -d /dev/video0 --stream-to=/dev/null”
I get something like:
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
<<<<<<<<<<<<<<<<<<<120.62 fps
I am also able to run the yavta application and get images from the camera.
When running ./opencvGui I had previously deleted the line
dtoverlay=ov9281 from config.txt because I found out that the drivers are different (although this is
not documented anywhere)
To the command: “dmesg | grep ov928”
I get:
[ 5.898580] ov9281 10-0060: Detected OV009281 sensor
[ 32.475627] ov9281_dvdd: disabling
[ 32.475638] ov9281_dovdd: disabling
[ 32.475650] ov9281_avdd: disabling
I have read all the related topics I found and I know I am not the only one experiencing this problem. I hope you could help me.
Problems you were having?
When trying to execute any arducam application I get “init camera status = 4099” error
The dmesg log from your hardware?
[ 6.048288] ov9281 10-0060: Detected OV009281 sensor
Troubleshooting attempts you’ve made?
I have tested the same camera in raspberry pi 4 (8 Gb ram) and it works with no problems.
If I follow the steps described here: OV9281 1MP Global Shutter Camera for Raspberry Pi - Arducam
The camera works as expected.
The I switch to the instructions in here:
Before doing all the process, I remove the line dtoverlay=ov9281 in config.txt
What help do you need?
I need a solution to be able to run the sdk examples.
I’ve got the same issue - I was told that they have not tested on the CM4. I’ve asked for the tests to be done as I need it working but no response; silence - which is weird because Arducam have previously been very responsive… I’m on the 16MP Sony IMX298 camera but basically have the same issue as you. I’m having to look for an alternative supplier as we need this on the CM4.
I’m very sorry that it took so long to reply to you. We have updated the MIPI_Camera library file and added the version you are using now. You can download it again and try it again. As you said, when using MIPI_Camera library, you need to comment out dtoverlay=ov9281.
Hello, I have tested the new driver and works fine with the evaluation board. However, in the board we designed it gives you “init camera status = 4100”. However, there are no errors with the yavta application.
My question is the following:
Does the camera checks the crypto chip that comes installed with the camera board?
In our current desing, the cryto chip is not installed. However, we have design it to install it if needed.
If the crypto chip is required for the camera to work, my next question is:
Is there any way to buy them from you?
For our design, I guess that we would need to buy the stand alone camera:
Yes, our driver will detect the encryption chip, if not, the driver cannot be used normally.
We are very sorry, our encryption chip is not for sale. If you use our driver, you can only buy our products. If it is a self-designed board, you can only develop the driver yourself.
