StereoPi Not Booting

My board does not seem to be booting. I have a Raspberry Pi Compute Module 3+ connected (I have no other way of testing this module, but it is brand new). I have two Raspberry Pi Camera v2.1 modules connected. I am providing 5.0VDC at up to 4.0A. The board is drawing between 0.123A and 0.129A steadily, depending on what is connected. The only sign of activity I have is the three red LEDs are coming on labeled 1.8V, 3.3V and another one by USB SLAVE. I do not have the USB SLAVE jumper shorted.

I have tried two different MicroSD cards: one with the SLP image, and another with Raspian that works in a Raspberry Pi. I tried two different monitors. I have tried without the camera modules connected. I have tried without any USB devices connected. I have tried removing and replacing the compute module many times. If I connect an Ethernet cable, I get no lights on the jack. I have waited several minutes each time to see if an image does eventually show up on the screen, but each time, just 3 red lights.

I don't know what else to try. Please help!

Looks like you are using not "Lite" edition of CM3+, but eMMC equipped. Can you clarify this please?

Yes, that is correct. This is not the CM3L. See attached picture. Is the eMMC-equipped module compatible?

Yes, of course. You can upload Linux image to eMMC.
To say briefly, you can use either micro SD, or eMMC (like in reference RPi devboard), as they uses the same SDIO lines.
You can read details here in our Wiki.
One notice for you. If you'll upload our S.L.P. image to eMMC, Linux partition will take 2 Gb of the eMMC size. All other space will be formatted to FAT32 for saving photo and video.

OK, that is good news. Assuming I had bootable images on both eMMC and MicroSD, how would I select between them? Just the presence of the MicroSD?

Thanks for the link to the instructions. I had not seen this information. We should add a link to it on this page https://wiki.stereopi.com/index.php?tit ... e_StereoPi

I am stuck on those instructions at the `rpiboot.exe` step because I am running Ubuntu 18 and not Windows. Is there a similar solution for GNU+Linux? Do these instructions apply? https://www.raspberrypi.org/documentati ... lashing.md

Either micro SD, or eMMC. If you try to use them both, they will conflict.

Yes, thank you. I definitely need to add this link there.

Yes, you can use these instructions for Linux from official Pi guide youre mentioned.

Excellent! I followed the instructions for compiling 'usbboot', writing the image with 'dd' and remounting the RPi partitions. I then edited the 'stereopi.conf' file and changed "video_mode=2D" to "video_mode=3D", then unmounted the device and removed the USB Slave jumper. After reconnecting everything again, everything seemed to work like a charm! Thank you, Realizator!

rlhelinski, I've added eMMC notice in "Basics" in our wiki, and also a comment for Linux users in "Uploading eMMC" section (point 5 in this text). If you have any suggestions or fixes for that articles - please let me know, and I will fix our guides.

I have the similar problem. All settings and Stereo Pi respondings are the same but I use a Raspberry Pi Compute Module 3 lite.

Hi Lashchev,
Please try to do first steps:
1. If you have any classic raspberry Pi, insert your micro SD card and test, that system start boot.
2. Disconnect all equipment from the StereoPi (monitor, RJ45 cable, USB dongles etc.). Just keep power, your CM3+ Lite, micro SD and HDMI.
3. Try to power on.

If boots starts, and red LED near camera connector blinks - it means that system boots.

I did all of these steps. Nothing is changed. Just black screen on a monitor
appears and Red LED near USB Slave is on when Stereo pi is powered on.

У меня та же проблема с Compute Module 3+ . И это похоже на то, что сгорел HDMI порт.
Если использовать SLP image, то программа с Compute Module 3+ в браузере работает как и сами камеры. Raspbian c OpenCV тоже
вроде как грузится, только там вход по ssh по умолчанию отключен как и VNC.
Как его вслепую настроить, чтобы зайти на raspberry без HDMI ? И можно ли зайти по uart на raspberry ?

If your HDMI port seems not working (black screen through HDMI) and you want to use Raspbian with OpenCV.
You have to make blind ssh install to enter the raspberry.
After burn the Raspbian image, connect usb-keyboard, ethernet cable to stereopi and boot.
Then press keys on usb-keyboard blind:
CTRL+ALT+t
sudo raspi-config +ENTER
down key 4 time + ENTER
down key + ENTER
TAB +ENTER
ENTER
ENTER
ESC

After that you will be able to enter the stereopi by ssh: pi - login, raspberry - password.
Further you can make VNC access.

*Will be better if we have Raspbian image+openCV with default ssh and VNC access for such a case.

В SLP SSH дефолтно включен, в OpenCV - включим, идея хорошая.
Чтобы включить ssh вслепую, лучший способ - создать в /BOOT пустой файл с именем ssh или ssh.txt Обсуждение вопроса есть тут: https://www.raspberrypi.org/forums/view ... p?t=169905
Про HDMI - если шнур подключать после старта StereoPi, выход hdmi может выключаться операционкой. У вас это как происходит?

For enabling SSH you can also just add empty file named ssh or ssh.txt to BOOT partition like discussed here: https://www.raspberrypi.org/forums/view ... p?t=169905

Знаю об этой особенности raspberry. Шнур сразу включен в порт. И какое-то время он выдавал видео. Теперь просто черный экран, при этом нет сообщения "нет сигнала" (для ситуации, когда шнур вообще не подключен). Наверно порт убило статикой.

Там стоит защита от статики, но все сценарии конечно не предусмотреть. А с контактами hdmi коннектора всё в порядке? Один юзер сообщал, что у него коннектор отошёл.
