devc-seromap
Serial driver for the Texas Instruments boards.
Syntax:
devc-seromap [generic_options] [driver-specific options] [port_num[^port_shift][,irq_num][,k]] where:
- port_num
- The address of the port.
- irq_num
- The interrupt request (IRQ) number.
Runs on:
QNX OS
Targets:
aarch64le
Options:
This driver supports generic devc-ser* options. For information about those options, see devc-ser*
in the QNX OS Utilities Reference guide of the QNX SDP 8.0 documentation.
In addition to the generic devc-ser* options, this driver supports the following options:
- -a
- Use Auto-RTS when hardware flow control is enabled.
- -b number
- Define initial baud rate (default 115200).
- -C number
- Set size of canonical input buffer (default 256).
- -c clk[/div]
- Set the input clock rate and an optional divisor.
- -E
- Set options to "raw" mode (default).
- -e
- Set options to "edit" mode.
- -F
- Disable hardware flow control.
- -f
- Enable hardware flow control (default).
- -I number
- Set size of raw input buffer (default 2048).
- -l 0|1
- Enable or disable loopback mode using the following values:
- 0 — disabled
- 1 — enabled
- -M
- Disables the MSR interrupt.
- -O number
- Set size of output buffer (default 2048).
- -o log=tx|rx|all logging directory
- Enable data logging to specified directory (default directory = /dev/shmem).
- tx — Log transmit communications
- rx — Log receive communications
- all — Log both transmit and receive communications
- -S
- Disable software flow control (default).
- -s
- Enable software flow control.
- -t level
- Set the receive FIFO trigger level. The valid values are 8, 16, 32, 56, or 60. The default is 16.
- -T level
- Set the transmit FIFO data trigger level. The valid values are 8, 16, 32, 56, or 60. The default is 8.
- -v
- Set verbosity level..
Examples:
Disable the hardware and software flow control, start the driver in edited mode using 115200 baudrate with a clock of c48000000/16 with base address 0x48020000 with a port shift of 2 on IRQ 106.
