When I follow the office document to install all configuration.I can use i2cdetect oled.But run the example console the error: sys_info.py: error: I2C device not found on address: 0x3C.
I hava 2 128x64 oled and one on ubuntu pi is ok another on this raspbian arm64.When I switch 2 oled on ubuntu one every is ok.Here is the detail console for raspbian arm64(I add one line print(args) in demo_opts.py#line51, python version is 3.9):
