OLED display on OrangePi Zero H5

[Matthai]

Hi, I have a OLED display on OrangePi Zero H5. OLED is SSD1306 (128 x 64 pixel) and is detected with i2c scan. I used this library: https://github.com/codelectron/ssd1306 and it was working just fine.

 

However, after some time (it is possible that it was after some update) OLED display stopped working - it is showing just random pixels. I checked soldering (it is OK), even replaced OLED with another one, but no luck.

I am running fully updated Armbian (10.9), uname -a says:
 

Linux myopi 5.10.21-sunxi64 #21.02.3 SMP Mon Mar 8 00:45:13 UTC 2021 aarch64 GNU/Linux

 

Is there any tutorial how to set up OLED display with OrangePi Zero H5 and H3 version and any hint what could be wrong in my case? Because as I said, display was already working, and I did not change anything in hardware...
