6.2.2 Built-in Help
The admin console has a built-in help system which is accessed by the
help
command. The
help
command will print a list of all top
level commands:
WPK> help
*************** Root commands ****************
aem AEM Configuration and Information Commands [ avg, calibrate, calinfo ]
boardid Commands for board ID probe. [ list, probe ]
dbg Debug interface status and control [ info, mode ]
dch Datachannel control and info commands [ info, message ]
discovery Discovery service commands. [ key ]
net Network commands. [ dnslookup, ip, mac ]
pti Packet trace interface status and control [ config, disable, dump, ... ]
quit Exit from shell
serial Serial channel commands [ vcom ]
sys System commands [ crashlog, nickname, reset, ... ]
target Target commands. [ button, go, halt, ... ]
time Time Sync Service commands [ client, disable, info, ... ]
user User management functions [ login,]
The
help
command can be used in conjunction with any top level command to get a list of sub-commands with descriptions. For exam-
ple,
pti help
will print a list of all available sub-commands of
pti
:
WPK> pti help
*************** pti commands ****************
config Configure packet trace
disable Disable packet trace
dump Dump PTI packets to the console as they come
enable Enable packet trace
info Packet trace state information
This means that running
pti enable
will enable packet trace.
6.2.3 Command Examples
PTI Configuration
pti config 0 efruart 1600000
Configures PTI to use the "EFRUART" mode at 1.6 Mb/s.
Serial Port Configuration
serial config vcom handshake enable
Enables hardware handshake on the VCOM UART connection.
6.3 Virtual UART
The Virtual UART (VUART) interface provides a high-performance application data interface that does not require additional I/O pins
apart from the debug interface.
The Wireless STK makes the VUART interface available on TCP/IP port 4900.
6.3.1 Target to Host
Target to host communication utilizes the SWO-pin of the debug interface through the ITM debug peripheral. This approach allows a
sleepy target device to enter all energy modes and still wake up intermittently to send debug information. The baud rate of the SWO
data is locked to 875 kHz.
VUART utilizes ITM stimulus port 0 for general purpose printing. Silicon Labs' networking stacks utilize ITM stimulus port 8 for debug
printing. The data on port 8 is encapsulated in additional framing and will also appear in the Simplicity Studio Network Analyzer.
