amptest(1) Qualcomm Atheros Open Powerline Toolkit amptest(1)
NAME
amptest - Qualcomm Atheros PLC Test Applet Loader
SYNOPSIS
amptest [options] [file] [file] [...]
DESCRIPTION
Download and execute one or more test applets on the local Qualcomm Atheros PLC device. An applet is a small firmware
image that can be started by the bootloader and that returns to the bootloader when done. This program is an alternative
to program int6ktest but has been replaced by program plctest.
A Qualcomm Atheros firmware image file may contain one or more applets. Each applet is preceded by a header that speci‐
fies the image size, load address and start address. Program amptest sequentially downloads and executes each applet
found in each image file specified on the command line. It waits for each applet to complete before downloading and exe‐
cuting 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 chains to be executed using one command. A chain may consist of one file containing multiple applets
or multiple files each containing one applet or any combination of single and multiple applet files. The chain 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 Qualcomm Atheros Powerline Toolkit contains a set of legacy applets in folder applets. These were designed for use
with program int6ktest and most will not display console messages properly using this program. A new series of compati‐
ble applets are under development and should be available through 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 Sequentially execute and re-execute all applets in all files on the command line until the program is terminated
with ^C.
-q Suppresses normal progress and status messages.
-t milliseconds
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 hexadec‐
imal 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 Cause the program to exit on the first error instead of moving on to the next applet. Error exits return a non-
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.
# amptest abc.nvm
The following example will sequentially download and execute the images in each file abc.nvm, def.nvm and ghi.nvm in
turn.
# amptest abc.nvm def.nvm ghi.nvm
