Debug Server Script (*.js) to control power to the micro controller

Nikhilesh Saggere

Hi,

I have the following requirement,

1) i would like to power up the micro controller before i begin the test case execution, complete the test execution and at the end power down the micro controller.

I would like to do the power up/down via .js script files, either through calling a external .js or internally in the same script by writing certain commands.

Please help me if there is any way to accomplish this.

Microcontroller (TIVA C series) - is powered with external power source.

Any mechanism or approach to either communicate to the external power source or turning off/on the power internally should be good.

2) In certain test cases i would like to write a particular memory location and then wait for certain time, such that

software running on the controller reads the (written value) and perfroms the computation and then i want to measure

or monitor the updated value after some time (say 5 seconds)

Please help me with this as well.

Thanks,

The most commonly used solution is a type of remote power reboot switch like below:

For those remote switches, there is often a way to toggle the switch via some command-line command. You can call this command from your script.

You can either do an asynch run and then wait 5 seconds before reading memory or you can do a standard (synchronous) run with a 5 second timeout and then read memory.

Thanks

Thank you Ki.
1) Can you point me to any example (if available) to show how we can call the external commands or other .js using javascript.
2) SetScriptTimeout is the API that are you referring? or can we introduce wait in some other format/DSS API?

Appreciate your help.

You can use Java Runtime.exec. But there are several gotchas as in the article below:

http://www.javaworld.com/article/2071275/core-java/when-runtime-exec---won-t.html

I wrote a little javascript (Runtimejava.js) include help file that you can include to your script. There is a synch and async run function you can call

You can download the script from: http://software-dl.ti.com/ccs/esd/apps/include_js.zip

Example:

load("./include_js/RuntimeJava.js");

var rt = new Runtime();

ret_val = rt.runSynch("cmd /c copy R:\\" + resultsFileName + " " + resultsPath + " /y");

yes, that is the API.

Or you can use any standard Java wait routine:

Thanks Ki - one question what is the significance of "/c" in the command, could not understand that.
Anyways i have tried a sample copy and execution of perl script using this command; it is working.

That is specific to the DOS "cmd" command
