Trouble connection target from CCS

Helge Kruse
Intellectual 435 points

I experience problems to connect the MSP430 target with the MSP-FET430UIF JTAG adapter. The most frequent error message is:

Error: MSP430: Error initializing emulator: Unable to load C:\Program Files (x86)\Texas Instruments\ccsv4\DebugServer\drivers\msp430.dll because The specified module could not be found.

Other errors are:

Error: MSP430: Error initializing emulator: No USB FET was found
Error: MSP430: Trouble Reading Memory Block at 0x13d2 on Page 0 of Length 0xb: Could not communicate with FET

The error can be solved by terminating CCS, power cycle the FET and restart CCS. This is very annoying when I need to restart CCS for each debug session.

CCS version is 4.2.4.00033
OS version Windows7(64-bit)

Is CCS incompatible with the 64-bit version of Windows7? How can the problems be fixed?

    Hi Helge,

    when you connect your FET to the computer, how does it appear in the device manager?  Are there any warnings?  Does it appear as a CDC USB device or as a different type of USB device?  Do you see the virtual MSP COM port?  Do you know what MSP430 dll version you have?

    Best Regards,

    Hi Lisa,

    there is no "CDC USB device" visible in the device manager. All I can see is a "MSP-FET430UIF - VCP (COM11)" entry at the Ports "(COM & LPT)" node. There is no warning at this device or any other communication device.

    The version of the MSP430.dll is 2.4.8.2, modification date: 2011-03-10, size: 364.544..

    Regards,
    Helge

    Hi Helge,

    ok, yes you are using the v2 dll.  A few more details may help us debug what might be triggering this

    -do you have multiple CCS versions installed?

    -does CCS ask you to upgrade the firmware on your FET?

    -do you have to do this for all of your projects?

    Your device does seem to be being recognized properly.  It seems like the firmware version on your FET could be a potential source of the problem.

    Best Regards,

    Hi Lisa,

    I have additionally installed CCSv5. The purpose for this was an evaluation for another microcontroller. This evaluation is completed and I don't use CCSv5 anymoore.

    When switching between the CCS version I was promted to upgrate the firmware of the FET. Since this last transition from CCSv5 use to CCSv4 I was not asked anymore.

    I have currently only one active workspace with one executable project. The other projects in the Eclipse workspace are libraries used by the executable. So I can't say if this problem resists when using another debug configuration or in another project. I could try to use another workspace after the weekend.

    Best Regards,
    Helge

    Hi Helga,

    ok please try the following two things

    1- please look at this wiki.  Grab the upgrde/downgrade utility.   Make sure to run the downgrade and try this.

     

    http://processors.wiki.ti.com/index.php/MSP_Debug_Stack

     

    2 - the free flash programmer from elprotronic can be found here www.elprotronic.com  

    This is also a good tool to manage FET firmware versions.  Try to roll back a version or two.

     

    Please give these things a try and keep us informed.

    Best Regards,
    Lisa
