  • First please ensure you have a proper connection between the Kindle and serial adapter - at first glance you seem to have some kind of short between Rx and Tx or some problem with the GND connection (please also unplug the USB when using serial just to prevent some strange problems).
  • Also check if your serial adapter runs in 3.3V (ideally 1.8V, but they are sometimes hard to get), as 5V might be too much for the UART circurity.
