UART not working despite labeled RX/TX/GND pads on Android 11 board
Reverse engineering an Android 11 OTT board. It has labeled LINUX_RX, LINUX_TX, GND UART pads, but connecting a 3.3V USB-TTL adapter (TX↔RX, GND↔GND) gives no boot logs at any common baud rate (115200, 9600, etc.).
Am I missing something, or could UART be disabled? Any tips?
