MSP430 Fet firmware downgrade

Other Parts Discussed in Thread: MSP-FET, MSP430-FLASHER

Hello,

I'm following the instructions on: http://processors.wiki.ti.com/index.php/MSPDS_Debugger_Up-_and_Downgrade#Downgrade_back_to_old_MSP430.DLLv2

But after the last CCS v6 update my start menu looks like this:

(I can start CCS using the CCS 6.0.1 icon)

It reports 6.1 though:

I'd like to invoke the downgrade tool directly (command line if possible).

Where can I find the downgrade tool in the CCS directory?

Regards,

Lo

    The UpdateTool.exe resides in c:\ti\ccsv6\ccs_base\DebugServer\drivers

    Lo2,

    The downgrade utility was a temporary fix for a specific compatibility issues when upgrading between some of our older DLLs and certain older versions of IDEs. This is no longer needed and is discouraged. We encourage all users to update your MSP-FETs to the newest version. this will be done automatically when downloading code when using CCS (or other IDEs). Please make sure your IDE is up to date to ensure the latest version of the DLL is loaded onto the MSP-FET.

    Any particular reason you are trying to downgrade your FET? What issue are you having here?

    Regards,
    JH

    Hi Jace,


    thanks for the reply. Yes there is a very specific reason: I'm working (maintenance) on old project which uses an old version of the IAR embedded workbench.

    This one requires firmware V2, hence the downgrade. I tried upgrading to a newer workbench version but that would require quite some bit of reworking of code parts which I'd rather leave untouched. So I resurrected the old development environment. Now I've got two MSP-FETs one V2 and one V3.

    It would be nice to have a download on the wiki for V2 firmware (including the update tool binary) similar to the MSP430-Flasher.

    I hope I was the last one who tried to do this but I'm afraid I'm not.

    Regards,

    Lo

    Lo,

    After doing some digging, I was able to find the same utility within my CC6 installation. You will have to navigate to where you installed CCS6 from there go to ccsv6 -> ccs_base -> DebugServer -> drivers . In this folder you should see quite a few things, but the important ones are UpdateTool.exe and a few .bat files that say V3V2 and V2V3 . The V3V2 is the v3 to v2 down-grader and the other is the up-grader.


    For my installation I had to go to C: ->TI -> ccsv6 -> etc.etc.
