Re: How to connect via WiFi

Hi srathinagiri , First, you don't need the RPIBOOT and USB_CLI jumpers installed. PRIBOOT is used for eMMC-equipped CM4, and in your kit you have CM4 without emmc. USB_CLI is for the very special advanced mode, and you don't need it too. So please just remove both jumpers. Your configuration files ...

Re: How to connect via WiFi

Hi srathinagiri, If you've entered all WiFi credentials (name and a password) right, StereoPi should connect to your router. The connection was successful since you can see it as an active client on your router. Now you can access the administration panel. You can do it two ways: 1. type "stereopi.l...

Re: picamera.exc.PiCameraMMALError: Failed to enable connection: Out of resources

Hi atrunyan, Am I got it right that you are using the fresh RaspiOS installation, but not our ready-to-use OpenCV RaspiOS image? If yes, please check the GPU memory in config.txt (gpu_mem=...) You see, Python and Picamera libraries require much more memory than the regular camera use. Set this value...

Re: Saving photos to USB drive

Hi joedevivo,
Since our file system is read-only by default, we keep all logs for the current session here: /tmp/cams-data.log
Please note this is the temporary path and it is erased after reboot.

Re: Camera control callback cmd=0x4f525245 mmal: No data received from sensor.

Hi pedrojvs,
I'm glad it works for you now!
Looks like it was the connection issue for one of the cameras' ribbon cable.

Re: Camera control callback cmd=0x4f525245 mmal: No data received from sensor.

Hello pedrojvs, In 99% this message means the connection issue. Let's check the connectivity. You might have 1 camera connection issue and 2 cameras issue. The second case usually means wrong camera ribbons orientation. Please check two things: 1. please run "vcgencmd get_camera" If you see "support...

Re: BEWARE! New Raspberry PI OS version Bullseye may break existing projects

Yes, I'll update the Wiki soon.
As for the libcamera - at least we know it supports hardware h264 encoding :) But MJPEG is not supported yet. While we are waiting for the official stereoscopic support in Bullseye, we try to test all other options we have now.

Re: customize raspistill

amphi, under the hood we are using the Raspberry application for taking photos - raspistill. As I remember, it has no option like you mentioned. For each photo it should do the full cycle of the sensor adjustments, and also a set of post-processing things. The only thing which is close to your aim i...

Re: Saving photos to USB drive

Hi joedevivo, A half of my StereoPis is equipped with eMMC. After the first boot, SLP2 formats all free space on eMMC to FAT32, and images and photos are saved in this partition by default. So it's fine to use eMMC for this. I use onboard file manager for downloading images and videos. As for the US...

Hi Tallman64, If you see 2-camera output on your monitor, it means we can exclude the connectivity issues. 1. Ethernet If you connect StereoPi v2 by ethernet cable to the hub (but nit to the PC directly), it should be visible in the network regardless of the WiFi settings. We always use Ethernet as ...

Hello Stéphane, Thank you for your notice! Actually, I have a talk with Gordon Hollingworth from RPF a month ago, and here are some news: 1. RaspiOS Buster now is considered as a candidate to LTS version. LTS means Long Time Support, and expected support range is up to 2026. Since Buster has all fun...

Re: customize raspistill

Can the time interval between the recordings be shortened in any other way? Could you please explain your task? In some cases, it is easier to record a video with low FPS instead of taking images. It depends on your aim. p.s. we are using the '-np' key in raspistill by default (i.e. "no preview"). ...
