NAME
plctest - Qualcomm Atheros PLC Test Applet Loader
SYNOPSIS
plctest [options] [file] [file] [...]
DESCRIPTION
Download and execute one or more test applets to the local Qualcomm Atheros powerline
device. An applet is a small firmware image that can be started by the bootloader and
will return to the bootloader when done. This program replaces int6ktest and amptest
because is supports both old and new image file formats and the old and new powerline
device boot methods.
Qualcomm Atheros firmware files may contain one or more applets. Each applet is preceded
by a header that specifies the image size, load address and start address and other
information. Program plctest sequentially dowloads and executes every applet in each
image file named on the command line. It waits for each applet to complete before
downloading and executing the next one. The program terminates once all applets in all
files have been executed or some applet fails to complete within 60 seconds.
Most applets return to the Bootloader on successful completion so that another applet can
be downloaded and executed. This allows applet sequences to be executed with one command.
A sequence may consist of one file having multiple applets or multiple files each having
one applet or any combination of single and multiple applet files. The sequence will
break, after a timeout, if any applet in the chain fails to return to the Bootloader in
time. Failure to return in time may be either a good thing or a bad thing depending on
applet design.
This program is part of the Qualcomm Atheros Powerline Toolkit. See the APT man page for
an overview and installation instructions.
COMMENTS
The Powerline Toolkit contains a set of legacy applets in folder applets. These were
originally designed for use with program int6ktest and most will not display console
messages properly using this program; however, a new series of compatible applets are
under development and should be available through Qualcomm Atheros Field Application
Engineering.
Assuming a good set of applets are available, this program is ideal for testing reference
designs for performance and production units for defects. Applets may become available
for testing onboard connections, memory integrity and noise immunity. Consult with
Atheros Field Application Engineering for applet availability.
OPTIONS
-e Redirects stderr messages to stdout. By convention status and error messages are
printed on stderr while primary program output is printed on stdout. This option
prints all output on stdout in cases where this is desired.
-i interface
Select the host Ethernet interface. All requests are sent via this host interface
and only reponses received via this host interface are recognized. The default
interface is eth1 because most people use eth0 as their principle network
connection; however, if environment string "PLC" is defined then it takes
precedence over the default interface. This option then takes precedence over
either default.
-l Execute all applets in all files on the command line until the program is
terminated using ^C.
-p frequency
The polling frequency expressed in polls-per-second. For example, 1 means one poll
per second and 10 means ten polls per second. Overall wait time is count/frequency
where count may be modified using option -c. Overall wait time is always
approximate since operating system overhead and latency are not taken into account.
The default frequency is 5.
-q Suppresses normal progress and status messages.
-t timeout
Read timeout in milliseconds. Values range from 0 through UINT_MAX. This is the
maximum time allowed for a response. The default is shown in brackets on the
program menu.
-v Print additional information on stdout. Specifically, this option prints incoming
and outgoing frames in hexadecimal format on stdout. Output can be directed to a
text file for analysis.
-w seconds
Application timeout in seconds. This application will wait this long for an applet
to terminate and return to the bootloader before reporting an error and proceeding
to the next applet.
-x Exit program on first error instead of proceeding to the next applet. Error exits
return a non-zero value to the shell.
-X Exit program on first applet load instead of waiting for the applet to complete.
This exit returns a zero value to the shell.
-?, --help
Print program help summary on stdout. This option takes precedence over other
options on the command line.
-!, --version
Print program version information on stdout. This option takes precedence over
other options on the command line. Use this option when sending screen dumps to
Atheros Technical Support so that they know exactly which version of the Linux
Toolkit you are using.
ARGUMENTS
file The name of an Atheros image file. The image file may contain one or more images.
Each image will be downloaded and executed in turn until all images are executed or
an image fails to return to the Bootloader within 1 minute for some reason.
EXAMPLES
The following example sequentially downloads then executes each image in file abc.nvm in
turn. Each image must complete and return to the bootloader before the next one
downloads. Observe that no device address is needed because Atheros powerline devices use
address 00:b0:52:00:00:01 when in bootloader mode.
# plctest abc.nvm
The following example will sequentially download and execute the images in each file
abc.nvm, def.nvm and ghi.nvm in turn.
# plctest abc.nvm def.nvm ghi.nvm
