Hello, i have B037, i am using it with RPi4 on Bullseye (Latest).

i followed this procedure - Quick start - Arducam Wiki

In general, it is working, but i am getting lots of same error as output, and it is taking long time to get a picture, more errors in output, more time to wait! as you will see in log it may take seconds to get picture.

here is example:

In case of moving to single camera mode, this error disappear, so problem exist only with merging frames from camera.

The main concern is low framerate, i am not sure if this is an issue of that error, but this error defitatly effect it. I also want to know what is possible framerate with it on 2028x1520.

In addition, did somebody tried B0397 on RPi4 with Ubuntu?

Thank you!

Hi,
About Embedded data buffer error, you need to install the libcamera from Arducam website:
https://docs.arducam.com/Raspberry-Pi-Camera/Native-camera/Libcamera-User-Guide/

We do not support this framerate@2028*1520.

May the link below will help you.

Thank you @Dion so much!

With right versions this error disappeared, but the framerate is still small, now it is around 3.3hz (through PiCamera2).

Regarding the resolution:

$ libcamera-jpeg --list-cameras

do you know if it is possible to increase the framerate?

Hi,
You need to decrease the exposure time to increase the framerate.
