Hi Everyone,
After some years I'm returning to DIY projects. I build streamer based on RPI 3A+, with Protodac, USB hub, and supercapacitor for filtering. Setup is running on 5A power supply based on LM1084. Case is old&dead Kenwood CD player. It includes Waveshare 4.3'' display connected using DSI and I get flickering issue.
Tested so far:
-different power supply[ RPI micro usb port 3,5A] - no change
-only RPI + screen[nor external boards] + different power supply - no change
That would take hardware problem out of equation, for software:
- Installation performed via RPI Imager
- GPU acceleration in Moode setting is OFF
- from Waveshare FAQ - "sudo rpi-update pulls/6417" - throws error on incorrect tar/zip file
-Changing or adding "dtoverlay=vc4-kms-dsi-waveshare-800x480" in config.txt- no change
What can be done to fix this issue?
