Stereo pi (cm3+)

Help / Getting Started
1

Hello,

Can someone give me advice on how to use open HD with an CM3+ in combination with a stereo pi io board?

I have 2 CSI camera’s connected. Open HD doesnt recognise them and boots as an ground station. Same with only one camera connected. When i add the air.txt the pi thinks there is a usb camera (there isnt) but no official camera.

With the stereo pi image (S.L.P. Raspbian image) on the CM3 both camera’s are working as expected.

Hi :slight_smile:

You’ll have to grab the dt-blob.bin file from the stereopi wiki, unzip it and place the file in the /boot or OPENHD partition where the openhd-settings-1.txt file is located.

https://wiki.stereopi.com/files/dt-blob.bin.zip

I think we can just start including that file in our images for now, there aren’t that many compute module carriers and even fewer that would be useful on a drone, I only know of 2 at the moment.

Only thing i am struggeling with now is to enable both camera streams. Is this possible at this time?

Sure, put -3d sbs in the EXTRAPARAMS line in openhd-settings-1.txt
