Cross-wired Uart Ports between two Pine Boards via Cat5 Cable

I have noticed similar behaviour, but the other way around - if the serial adapter is connected to the pine but not plugged into the usb. I don't think you did anything wrong in your setup, there was just enough bleed through of power via the usb-to-serial to make the pine64 power led stay lit.

Edit: And unsurprisingly, there is a mention of this exact behaviour on the linux-sunxi page for the pine64...

Quote:A connected UART cable is leaking power and this causes some annoyances. For example, unplugging and plugging back a power cable does not reboot the board cleanly. Thus ensuring the availability of a reset button is recommended for doing any reasonable software development.
