|
NuttX per default reorders the serial ports (/dev/ttySx) so that the
|
|
console is always on /dev/ttyS0. If more than one UART is in use this
|
|
can, however, have the side-effect that all port mappings
|
|
(hardware USART1 -> /dev/ttyS0) change if the console is moved to another
|
|
UART. This option disables that re-ordering for 16550 UARTs.
