Query on mounting an sd card and stereo support in compute module 3

Tue Sep 12, 2017 11:32 am

Can anyone please put up a detailed step by step procedure for the following:

1. How to mount an sd card on a compute module 3 (with emmc)? For the compute module without emmc the procedure is same as how we work on rpi2/3 right (just to make it sure)?

2. Setting up a stereo camera (the hardware part) can be done from the following website:
https://www.raspberrypi.org/documentati ... -camera.md
but what are the necessary installations to enable stereo support (in order to use it for depth perception)?

I am a beginner who wants to use compute module just for the stereo support. There are no proper documentations which I could follow hence makes it so unclear and it gets so confusing! Can anyone please help me about it?

Stereo vision is something that I've been working on also but the project is on hold right now. This thread may give you some help viewtopic.php?f=98&t=183038
The most important leg of a three legged stool is the one that's missing.
It's called thinking. Why don't you try it sometime?

You can only do that as a USB device. The same interface that is used for the eMMC module is used for the SD interface.

FYI...there is a sub-forum specifically devoted to the Compute Module.

Thank you. But yeah I managed to make the cameras work but I am trying to find ways to synchronize both the cameras as I am using it for depth perception.

Y

Yeah thats the reason why the pi does not detect an sd card when we use compute module with emmc. There is a way to do it but I don't find how.

Yeah I saw that. What do they mean by wiring gpio from 22-27?
I am sorry and I am quite new to these. Could anybody please explain?

They mean to enable one of the SD interfaces on GPIOs 22, 23, 24, 25, 26 and 37. If that doesn't make any sense then you need to download a copy of the BCM2835 ARM Peripherals guide and read the GPIO section.
