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.

---help---
|
|
The bit width of registers. Options are 0, 8, 16, or 32.
|
|
Default: 8
|
|
Note: 0 means auto detect address size (uintptr_t)

config 16550_WAIT_LCR
|
|
bool "Wait for UART before setting LCR"
|
|
default n
|
|
---help---
|
|
Before setting the Line Control Register (LCR), wait until UART is
|
|
not busy. This is required for Synopsys DesignWare 8250, which
|
|
will trigger spurious interrupts when setting the LCR without
|
|
waiting. Default: n
|
|
|
|
config 16550_SET_MCR_OUT2
|
|
bool "Set MCR OUT2 bit high"
|
|
default n
|
|
---help---
|
|
Some platforms require OUT2 of MCR being set for interrupt to be triggered
