I installed it and it works fine, but the LCD flickers. I’ve attached a video to help explain.

Thanks

The forum does not support attaching a video file directly. You can upload it to Google Drive, Dropbox or any cloud server and share a link to it.

Did you reboot RPi after installing the firmware? The LCD requires fast I2C speed. The firmware build script sets that, but it is only effective after a reboot.

The link is not shared or the file doesn’t exist. Did you try to reboot RPi?
