Hello All, On the BBB Rev C schematic the tri-state buffer for UART0, U15, is wired with a pull-down for the 1A input (pin 2 on the device). For TTL level serial I/O, the high state is idle and ground is the start bit. So it seems to me the pin should have been pulled-up, not down, so that the input looks idle on start-up. What am I missing?
The reason I ask is I have BBB's mysteriously while performing a 'reboot' (no power cycle). When I attach a UART0 console to track it down the problem seems to go away, which makes me wonder if it isn't the UART itself.
