Help! Naked Stereo pi with cm3+ 32G; Impossible to setup?
Posted: Thu Feb 25, 2021 5:33 pm
So I think I made two mistakes which are making my life difficult:
Mistake 1: getting the naked stereopi
Mistake 2: getting the 32Gig cm3+ (ie not getting the "Lite" version)
My GOAL: Two stereopi's with 4 of the V2 camera's and I want them setup per the blog about synchronous 4 camera shots.
I would prefer it to use the usb connection that gives "ethernet over usb". But no way to set that up w/o being able to ssh in.
OR I soldered on a EDImax wifi dongle, so using that to get on my network or phone hotspot.
Main issue: With the "naked" version there is no possible way(for me) to SSH to the pi in order to setup the "ethernet over usb" magic or compile the C program etc.( I realize it is probably possible for someone...)
Question1: With the OpenCV image - is there anything I can do from windows in the boot partition to "activate/setup" the "ethernet over usb" (or get my EdiMax to work) ?
Question2: Does anyone have the OpenCV image with the ethernet over usb already setup?
So I have been trying very hard to get this working all this week. I am a bit defeated.
What works:
0) I can connect the jumper, connect the micro-usb and successfully flash the CM3+ [using the raspberry pi foundation flasher seemed to work best]
1) I can connect the jumper, connect the micro-usb, run the script "rpiboot.exe" and see the boot partition and other partition as mapped drives on my windows10 laptop.
2) I can connect the HDMI; With SLS image I can see the video from the cameras
So eventually I was able to get the Flash the SLS image and get it to work by:
1) updating to the stereopi.conf to activate wifi and connect to my home network.
2) soldering an EdiMax wifi dongle directly to the extra USB pins
Then it gets onto the network; the app on android effortlessly finds it, and seems fine, can ssh in. all is good from a hardware/testing perspective.
However, I need the "OpenCV" image... when I image that to the cm3+/stereopi I can't figure out how to get the EDIMax dongle to work. And I have no other way to be able to SSH and setup anything... totally thwarted. I was using the image from the wiki - the buster one: OpenCV Buster Google Drive Image
I also do have 4 other raspberrypi's I can use. A RPi3B V1.2 ; A model B+V1.2; A RPi4 Model B; A RPi2 Model B V1.1;
My thought right now, is to image the OpenCV to the RPi3B V1.2; SSH in. Setup per https://stereopi.com/blog/synchronizing ... opi-boards (compile the script, set it up in the scheduler, test it with the one camera on that pi. Try to setup the usb-ethernet gadget.
Then I hope to copy the SD card and image it back to the CM3+.
If anyone has another better, easier, smarter, faster way of achieving my goal, please let me know. Or if my plan is stupid and won't work, let me know.
