I got the following problem:
I need two cameras on my Raspberry Pi, so i bought a Waveshare IO-Base-A and a CM4 2GB. When trying to use two cameras with this setup, none of them work. Only one camera does work.
The official way on the Waveshare Wiki (https://www.waveshare.com/wiki/CM4-IO-BASE-A#CSI_DSI) doesn't work either, so i really don't know know what to do...
I do know that this isn't a problem that only occurs on my system, and it doesn't look like an Hardware-problem as well, since switching cameras etc didn't work for me as well. Editing the config.txt (on PiOS and Ubuntu Server) ends up with having 0 cameras that work. Only start_x=1 allows one camera to work.
Thanks for every answer

I cannot use the official Pi camera(s) using either the official Raspberry Pi "Buster" disk image or the Pi disk image provided by Gumstix:
Disk image referenced here--> https://store.gumstix.com/raspberry-pi-cm-fast-flash.html
Note: The Gumstix Pi image would "hang" on the rainbow colored splash screen during boot, using the image above. I am using the "fast flash" board to write the images, and have been able to repeatedly (successfully) install the standard Raspbian OS. FYI I have been using Balena Etcher, and it has worked with my other boards.
Also, I followed the official instructions to add camera support in an attempt to understand what I am doing wrong. vcgencmd initially reported no support or detection in raspbian. I was able to add camera support using the blobs mentioned here (I compliled manually and also used the precompiled variant):
https://www.raspberrypi.org/documentation/hardware/computemodule/cmio-camera.md
Final result:
vcgencmd get_camera : supported=1 detected=0
Lastly, yes the camera is enabled, and I have tested the cam/cable on other systems with no issues. I suspect the pin GPIO settings may be to blame, but based on the information in front of me (for this board) I should not be expecting to manually adjust those params. Thanks for any insight….hopefully this is an I-D-10-T error.
First off I should appologize, the page you referenced about getting the disk image is very out of date. We will work to update it soon.
My guess of why it's not booting is likely a hardware imcompatibilty, are you using a Raspberry Pi CM3+?
Give this image a try
https://gumstix-raspbian.s3.amazonaws.com/2019-12-29/raspberrypi-cm3/rpi-4.19.y/2019-09-26-raspbian-buster-lite.img.xz
That's a recently compiled Buster image that has some extra drivers added in to support Geppetto modules. The default Buster image should also work.
To properly support any of our boards, it's best to download the board support package for that particular design. In your case, you're using the Gumstix Pi Compute Dev Board, which can be found
https://geppetto.gumstix.com/#!/design/1045/
Please go to that page and click on the "AutoBSP" button on the top. That will prompt you to download a zip file that will contain some instructions and files needed to configure the Raspberry Pi.
Please let me know if you have any trouble.
Thanks,

I'm a developer for different mobile and backend systems and pretty new to network and hardware stuff. I want to build a system/network with 6 cameras placed 100m away in the field, which I want to control with a web interface. I know how to build such interfaces, but I have no clue how to connect the hardware. I thought about the following:
I need 6 cameras(*infos added below) standing side by side with ca. 1.5m space between. These should be connected to a switch, so a 100m wire (USB or LAN, I prefer LAN) goes to a RPI which can setup the web interface controlling the cameras like ".../whatever/camera-slot-ip-or-number".
As I said in the introduction, I have no clue how to start, because actually webcams using USB as a std, but does they provide wake on LAN features? Or is it better to do it with 6 USB-cams and several RPIs?
I hope someone with a better hardware understanding can help me.
Thanks a lot
Specification for the cameras:
HD is not needed, but it should recognize a 0,5cm round hole in a 50x50cm area properly. The distance between camera and object is 7-10m A color image should transmitted, but there only 2 main-colors.
EDIT:
draft 2.0:
Piping USB through a 100m cable is not easily going to work.
Some models of USB cameras can be used with the Raspberry pi, but the performance (speed of taking a picture, and image quality too) are better with the 'native' raspberry pi camera.
The Pi also has a built-in H.264 video encoder, so you can stream live video with relative ease if you want to. A quick and brute way of doing that is to pipe the output from the built-in raspivid application to your own application that then handles flow control and pipes the data further to a socket.
If wifi does nto work for you, then you could pick some other raspberry pi model with an ethernet interface and go that way.
Also, the cost of additional Raspberry Pis (especially the zero w) is so low that the easiest and most cost efficient thing might just be to one raspberry pi camera on 6 raspberry pi's. If connecting them with Wifi works in your application, you can use the Zero W model and then you just need to feed power to them via cable.
Thank you for the updated information. I am pretty much in agreement, I think, with Sami's answer but wanted to add a few more details that are a bit big and unwieldy for a comment.
If you look across the top of your diagram, you have 6 stations at 1.5m intervals, so the width of your diagram is 7.5m. That is easily within wifi range so I am thinking a wifi access point on any of the 6 stations and a 100m Cat 6 Ethernet cable down the length of your diagram to the front-end.
As your processing doesn't sound too involved, you can likely get away with just a Raspberry Pi Zero W and a v2 camera at each station and save a fair bit of money vis-Ã -vis Raspberry Pi 3B+.
One thing that does concern me is looking for 0.5cm from 7-10m. The lens on the Raspberry Pi camera is pretty wide angle and a 0.5cm hole is going to be awfully small at 10m in a wide angle shot unless at very high resolution. I haven't done the maths, but I think you will be looking for a telephoto lens if such a thing exists... the maths now follows.
The horizontal field of view (FOV) of v2 camera is 62 degrees, so half that is 31 degrees and the camera is 1000cm away. So:
tan(31 degrees) = half the FOV width / 1000
So, at 10m you will get 1200cm of stuff across your image and that will be imaged by 3,280 pixels on the sensor if you shoot at the very highest resolution. So, each pixel in your image will correspond to an area 0.3cm wide whereas you are looking for holes 0.5cm wide - so it will be pretty marginal as to whether you can make it out... maths is subject to revision after a glass of wine later.
currently I am trying to show my own UI and a third party virtual keyboard above the video which is displayed by omxplayer.
I am using a Raspberry Pi 3 (which is the reason for using omxplayer).
I am starting omxplayer from command line. I found the --layer n option but however it does not seem to change anything.
Did anyone ever come across something similar?
Thanks in advance
I have been experimenting with home home automation and want to turn my raspberry pi 3 into a hub not something my devices manually connect to e.g from the gpio pins. In many unsuccessful attempts I have tried OpenHab. I would like to mount a touchscreen with a GUI so I can e.g turn the lights on from this control panel instead of via phone or other hubs available like Google Home. If anyone knows how I might do this it will be much appreciated.
It seems like home-assistant with floorplan would work for this. It takes a little bit of configuring but well worth it.
I've seen a lot of projects, tutorials and how-to's on the web regarding the Raspberry Pi.
I've just received my first Pi in the mail, and I can't wait to get tinkering with it.
Of course, doing any of these things is going to be a difficult process, however, as my experience with the Pi is next to none, I wondered about the capabilities of what I want to do with my first major project.
I'd like to be able to build an on-board computer for my car. I've seen several projects regarding this, and I've seen some good guides online.
However, none that I have seen will do EVERYTHING that I can think of....
I'm assuming that my 8GB SD card will be limited to only a selection of these specifications, however, here's a list of what I'd like the solution to be capable of, and if anyone knows any reason why this isn't possible, please give me a heads up :)
So...
I'd like a front-end GUI (on a 7" touchscreen monitor) with a menu to navigate the options, which will include
From this menu, I'd like to be able to select (and of course, run) the following:
Media center (I've seen things like XBMC etc.) - I'd like this to be capable of taking over the radio unit and playign mp3's etc (possibly from my iphone!?)
GPS/SatNav - I don't know how possible this is and I assume i'd need a 3G card or something...
Reverse parking camera (stick a webcam in the rear view window) etc (I've seen good tutorials for this)
Connect my phone with a bluetooth thingy(?) so that I can add a USB mic and play the receiver audio through my speakers (acting as a hands free kit)
I'll add more ideas too...
I'm not questioning if each of these individual specifications are possible, I am asking if they are all possible through one solution as a whole, with a GUI to navigate through them?
Thanks for any help.
Cal.
It is all possible, all in one bundle. 8gb is more than enough for everything, it'll only limit your music collection. The only question is: how much work are you able/capable of doing. That will be the limiting factor, not your Pi.
Short answer is yes, all exist and the pi can handle it. But you'll be writing a lot of custom software to make them interoperate.
