Problems launching FRAM_GUI.exe for MSP-EXP430FR5739 Experimenter's Board

Matt Hosler

Other Parts Discussed in Thread: MSP-EXP430FR5739

I am trying to use the GUI in the MSP-EXP430FR5739 Expiermenter's Board. I have downloaded SLAC492.zip file and unzipped it. When I launch the file FRAM_GUI.exe that is contained inside, I get a Java Virtual Machine Launcher error that says "Could not find the main class. Program will exit!".

What do I need to do to get the FRAM GUI working?

Incidentally, Section 1.5 of the MSP-EXP430FR5739 FRAM Experimenter Board User's Guide (http://focus.ti.com/lit/ug/slau343/slau343.pdf) says to double click "MSP-EXP430FR5739GUI.exe to load the PC application." Since that file is not located anywhere in the SLAC492.zip file, I am assuming that this an error in the User's Guide and they are referring to the FRAM_GUI.exe.

Thanks.

Matt,

I get that same error when I don't unzip and extract the files to my hard drive. Are you sure you copied all the files to the same individual folder? It sounds like a Processing error.

Thanks,

Jacob

Yes, I unzipped them all to the same folder. And I launched it from that folder once it was unzipped and saved there.

Hmm. Have you deleted and re-downloaded to try again? Can you verify on another machine?

What is your machine setup?

Thanks,

Jacob

I re-downloaded and re-installed and had the same results. I do not have a second machine to verify on.

My machine setup is:

Windows XP version 2002 service pack 2

Intel Core 2 Duo P8600 @ 2.4 GHz

Java Version 6 Update 26 (build 1.6.0_26-b03)

Matt,

I don't know what to tell you. I am on virutally the same machine, but I have XP Service Pack 3. I only have Java up to update 22, so I guess you are ahead of me on that.

I am thinking that something strange happened when you were downloading the zip file and it glitched on install. That happens to me sometimes when I am not on the LAN at the office and am on my WiFi at home.

I don't see any reports of the same problem, but I will forward to our tools team to see if there are any known incompatibilities and get back to you.

Thanks,

Jacob

It is possible that the Java class loader has a problem with a too-long path to the main JAR file (or the exe) or if the path contains accented characters or spaces.

I had the same problem with the LaunchPad GUI and the FRAM GUI.

I resolved it by:

updated Java to Version 6 Update 26
removed Java Web Start
removed Java 2 Runtime Environment, SE v1.4.1_02
removed J2SE Runtime Environment 5.0 Update 6

One or more of these caused this problem.

Dan,

Thanks. That worked for me. I was already at Java version 6 Update 26. Then I uninstalled all version of Java 2 Runtime Environment and all version of J2SE Runtime Environment 5.0. Then the GUI worked!

Thanks for your help.

Looks like the GUI requires Java 6, but the default JRE was one of the previous installations.
