Hi, I'm trying to connect this
screen to stereopi with compute module 3, but all a got so far is black screen with backlit on.
Running on raspbian buster. I2C and SPI enabled and here's my config:
Code: Select all
hdmi_cvt 1024 600 60 6 0 0 0
I also tried to follow this
tutorial, but nothing really changed.
Any suggestion on what I am doing wrong?

I’ve looked into Waveshare Wiki for this screen.
The first thing I noticed in your config is that you’re trying to load both dpi24 and vc4-fkms-v3d overlays. It is not good idea, as they may give you hardware conflicts.
Second mention is that dpi24 overlay try to rearrange pins, and angry for resources: https://www.raspberrypi.org/documentati ... /README.md
It may affect on stereoscopic cameras support and conflict with our dt-blob.bin, so it is better to do some delicate pin arrangement analysis.
Also I’d like to ask, did you try to run this screen with a classic Raspberry Pi (ideally 3B or 3B+, as they have the same CPU as Compute Module 3/3+)?
