    Hi all! I’ve been using Raspberry Pi 3 and Controllino MEGA on a manufactured product for the past 2 years and we have recently move to the RPi4. We’ve been noticing UART pins failing (GPIO14&15) in our product recently. The only notable difference beside the RPi3 to 4, is a change from ttyAMA0 to serial0 communication port. Did anyone experience a failure of this kind? Any insight on what could be causing the pins to fail?

    Thanks!
