Re: SLP2 FAQ
What's the difference between stereopi-*.csuf and cosmostreamer-ng-*.csuf ?

Re: SLP2 FAQ
SLP2 is the special version of Cosmostreamer RaspiOS, focused on stereoscopic features. If you install the cosmostreamer-ng-*.csuf, you'll get the Cosmostreamer image without the specific StereoPi settings, which is useless.
It is better to install only the stereopi-*.csuf update files. All links on our Wiki are pointing to "stereopi-*.csuf" files.
BTW, Cosmostreamer desktop apps (for Mac and Windows) can be used with SLP2-equipped StereoPi out of the box.

Re: SLP2 FAQ
Hi I've been trying to get the stereo pi to booty but have been unsuccessful, I am getting an error during and can't even to a command line.
However when I use the sd card a raspi 2 it loads and I can get to web page (nothing really works but it does boot and run).
The error I am getting is:
brcm-pcie fd5000000.pcie: link down
mmc0: error -110 whilst initializing SD card
I see various related stuff but nothing that has the same error, any ideas what could be the issue?

Re: SLP2 FAQ
OK, I was able to get it to boot by using a different SD card ( a rather cheap 32gb ONN ) and reinstalled everything and it was able to boot.
Although i'm not too familiar with the specifics, it seems as RPI4 has issues with certain SD cards (Primarily sandisk from what I can tell).

Re: SLP2 FAQ
Lion XL, could you please try to record SLP2 image on the original card?
I'm trying to understand, is this a micro SD issue, or the supplier's image recording method issue.

Re: SLP2 FAQ
We prepared the big update for the SLP2. The updated image is available on our download page under the name beta-version-slp2-0.11.19.zip The size is 850Mb. It is recommended to write the full image to the micro SD card.
Key fixes:
1. Kernel updated to fix the "magenta issue" for Sony-based cameras (IMX219, IMX477)
2. HQ camera photo mode fixed
3. Extended video conversion options added (MP4, MKV for 3D upload to YouTube, TS container with the audio support).
4. Camera warm-up time moved to parameters. By default, it is 500ms, which sometimes is not enough for the camera to auto-adjust settings in the overlight conditions.
5. Video freeze in administration panel fixed (Safari browser issue).

Re: SLP2 FAQ
Hello Realizator, I installed the beta-version-slp2-0.11.19.
However, there is no stereopi.conf in this update.
Am I doing something wrong or is it the wrong file?

Re: SLP2 FAQ
I purchased a Stereo PI V2 and II have been unable to boot the Stereo Pi, I am new to using a PI and followed the online tutorial.
I have added the operating system (beta-version-slp2-0.11.19) on a micro SD card, when I boot the system it is just a black screen with the following error message:
1.7653611] brcm-pcie fd500000.pcie: link down
1.9478671] hub 2-0:1.0: config failed, hub doesn't have any ports! (err -19)
4.7156931] sd 0:0:0:0: [sda] No Caching mode page found
4.7157721] sd 0:0:0:0: [sda] Assuming drive cache: write through
I completely lost here. I have looked online for solutions and can't seem to find out what the issue is. I have also tried the micro sd card issued with the package, as well as being a brand new micro SD card to see if that would work and nothing, with the same error.
Could some please advise on what I can do?

Re: SLP2 FAQ
Hi MJB83,
In most cases the issue is poor camera ribbon cable connection, or CM4 connection. Since you are talking about tscreen messages, I guess you have a monitor connected, so you can do a few tests.
Since you are new to Pi, let's go a bit simpler way for the hardware test.
1. Please use another micro SD card from the kit with the OpenCV image. This RaspiOS image is designed for the monitor/keyboard/mouse mode and will simplify your first tests.
2. Please disconnect all equipment from the StereoPi (like tiny screens, buttons, etc). Just keep CM4, cameras and keyboard/mouse. Please check CM4 sits firmly!
3. Boot the device. After boot you should see the desktop. Run terminal, and type this command:
raspistill -cs 0
If you see the 5 seconds image preview - your first camera is working fine.
Then run this command:
raspistill -cs 1
If you see the image preview on the screen, youre second camera is fine too.
Please try these steps and let me know how it is going.

Re: SLP2 FAQ
Hi Realizator,
I’ve managed to get the OpenCV image file to boot on with the desktop running and I am using a monitor via hdmi.
The beta-version slp2.01.11.19 that’s not booting with the same error message.
have added the operating system (beta-version-slp2-0.11.19) on a micro SD card, when I boot the system it is just a black screen with the following error message:
1.7653611] brcm-pcie fd500000.pcie: link down
1.9478671] hub 2-0:1.0: config failed, hub doesn't have any ports! (err -19)
4.7156931] sd 0:0:0:0: [sda] No Caching mode page found
4.7157721] sd 0:0:0:0: [sda] Assuming drive cache: write through
I am unable to achieve booting slp2 to use the SLP2 interface use and see the stereopi.local
Any suggestions on what to do?

Re: SLP2 FAQ
Hello MJB83,
1. Could you please confirm that with OpenCV image you have a success with 'raspistill -cs 0' and 'raspistill -cs 1' tests? That's important.
2. For the SLP - did you try another micro SD card?
3. Try this thing. After recording the SLP2 image to the micro SD card, connect this card to your PC again to see the /BOOT partition files. Download the latest update file using this link and copy it to the BOOT part of the card. This is a way to update your SLP2 without booting. After that, please try to boot again.

Re: SLP2 FAQ
Hi Realizator,
Just to confirm that it was successful with OpenCV running raspistill -cs 0 & raspistll -cs 1 test ok for both cameras.
I have tried your recommendation for SLPs image using the existing and brand new SD by copying the stereo.csuf file to the boot card on a few occasions with no luck. the same error message on system boot during startup:
1.7653611] brcm-pcie fd500000.pcie: link down
1.9478671] hub 2-0:1.0: config failed, hub doesn't have any ports! (err -19)
4.7156931] sd 0:0:0:0: [sda] No Caching mode page found
4.7157721] sd 0:0:0:0: [sda] Assuming drive cache: write through
Also the screen goes black for around 3 to 5 secs showing the following:
/boot/splash.png: loading FAILED
this displayed at the bottom of the screen, then back the the original error message. All in all the same as before?

Re: SLP2 FAQ
Hi Realizator,
Do you have any recommendations/update on my SLP2 not working? I really need to Hager this up and running for a project I am working on.
Is there another version of StereoPi worth buying to get this feature running?
Any update would be greatly appreciated.

SLP2 and CM4 with 32GB eMMC
Hi Realizator,
I'm struggling to get my Stereopi v2 to boot. I have mounted the CM4 eMMC on Mac OS via the terminal using the below guide:
https://www.jeffgeerling.com/blog/2020/ ... mc-usbboot
This allows me to use the Raspberry Pi Imager to find the eMMC under the storage button. I downloaded the img file here:
https://www.mediafire.com/folder/nzr90vj8wp1l3/SLP
I can only use the file called slp2-0.8.19.img.zip because both the OpenCV image and the beta version both give the attached error when I go to write to the eMMC.
I write the slp2-0.8.19 image successfully, then when I go to boot, it starts, but doesn't complete and I get the attached messages in an endless loop.
Please can you let me know how I can solve this?
Thanks in advance!

Re: SLP2 FAQ
Hey MJR2022,
Older SLP V1 (i.e. slp2-0.8.19.img.zip) won;t work with StereoPi V2, since this version is old and doesn't know about CM4 existence. Thus it's not booting.
Did you try to unarchive image file first, and record it to the eMMC then?
Your screenshot says you're on Mac. I'm using Balena Etcher, and it writes both images from the "mediaflare" successfully. Could you please check it this way?

Re: SLP2 FAQ
I just recently bought the StereoPi v2 Camera Kit and the links above refer to stereopi-*.csuf files that don't exist anymore and cosmostreamer's website states it is $150, do we have to buy it now?
I guess what I'm asking is what are the new 2024 instructions to go from a blank microSD card to an up to date working StereoPi v2?

Re: SLP2 FAQ
Hello Fred,
I've fixed the broken links.
We also have two updated images (OpenCV and SLP, 2024 edition). The links can be found in the Download section of the Wiki, and here is the direct link: https://www.mediafire.com/folder/nzr90vj8wp1l3/SLP
