Problem capturing stills from camarray -12 mp synchronized quad camera bundle kit

  1. Where did you get the camera module(s)?


  1. Model number of the product(s)?


  1. What hardware/platform were you working on?

Raspberry Pi 4b

  1. Instructions you have followed. (link/manual/etc.)

Documentation for camarray and also the github repo for multi camera adapter v2.2

  1. Problems you were having?

Adapting code for multi-camera adapter for use with camarray. I have included the logs.

picamera_stdout.log refers to the messages I see when I run the program. picamera2_python3 refers to the logs that are printed to a log file when using picamera2 library on python3.

  1. The dmesg log from your hardware?

  2. Troubleshooting attempts you’ve made?
    Noticed that the imwrite function is not getting any data from the camera. different way to initialize the camera? When running the example on documentation it also prints these lines before previewing the camera.

[1:22:42.341011601] [24247]  WARN V4L2 v4l2_videodevice.cpp:1803 /dev/video0[14:cap]: Zero sequence expected for first frame (got 2)

We also get this error when running the commands:

i2cset -y 10 0x24 0x24 0x00
libcamera-still -t 0

[1:35:34.509995806] [24393] ERROR IPARPI cam_helper.cpp:181 Embedded data buffer parsing failed

Here is the code:

  1. What help do you need?
    Entering into a mode that enables us to capture stills from the camera hat.
    Is there information available to send camera to into stills mode with rpi gpio?

we were able to capture stills using the libcamera-vid program if we can’t get it working any other way.

May you contact [email protected] and post the link?

Thank you yes I’ll do that. Thanks for the support.
