sptest Command-Line Syntax

dev=device_name

Identifies the serial port(s) to test. There is no default value. You must specify a device name such as: 

• se0,

• zs0, zs1

• zs2, zs3

• ..., ...

porta=port_name

The name of the first device of a serial device pair. The default is a.

T=test_type

Specifies the type of test to run: 

• a= runs the test on port a.

• b= runs the test on port b.

• a_b= runs the test on ports a and b sequentially.

• a_b_concurrent= runs the test on port a and port b concurrently.

• a_to_b= runs the test from port a to port b.

L=loopback_type

The type of loopback connector attached to ports: 

• No_modem_a_to_b

• Internal_a_to_a__b_to_b

• Plug_a_to_a__b_to_b

• Modem_a_to_b

M=mode

The default test mode is asynchronous. Specify one of the following modes: 

• asynch

• synch

• both

D=data_pattern

Selects the data pattern to transfer. The user can select: 

• Random

• Sequential

• Alphanumeric

• 0x00-0xFF

AB=async_baud_rate

Asynchronous baud rate (default = 9600). The valid values are between 110 - 460800.

Note: Some platforms can only support asynchronous baud rates up to 38400 or 76800. For baud rates greater then 153600 the serial line drivers must be set for RS-423 mode and not RS-232 mode.  

S=async_data_size

Asynchronous mode total number of bytes to write; from 1 to 10000 bytes. 

par=none|even|odd

Parity used in the async loop test. Default value is none. 

BS=1|10|100|1000| 3000| 5000|10000

Number of bytes in each write during async loop test. Default value is 100. 

F=flow_control

Asynchronous mode flow control: 

• Hardware (RTS/CTS)

• Software (xon/xoff)

• None

B=sync_baud_rate

Synchronous baud rate (default = 9600). The valid rates are between 110 - 256000.

Note: Some platforms can only support synchronous rates up to 38400 or 76800. For rates greater then 100000 the serial line drivers must be set for RS-423 mode and not RS-232 mode. 

DP=sync_drop_tolerance

Synchronous mode drop packet tolerance (default=20 percent). 

P=sync_poll_waitt

Synchronous mode additional wait time during poll (in seconds).
