FTCJTAG.dll error/issue .... FAQ/Work Around

Hi Ed,

Have you put them here?  Do you still get the same error?  Have you done a reboot afterwards?

C:\ccsv5\ccs_base\DebugServer\drivers

Please keep us informed.

Best Regards,

Lisa

Lisa,

My CCS install is in c:\ti\CCS5.2\ccsv5\ccs_base\DebugServer\drivers

I have put both files in that directory as well.  Same results.

Hi Ed,

what target are you using? Did you try a reboot?   Have you tried downloading the standard ftdi drivers from the web?

Eg we post a version of Stellaris ones here:

Hello Lisa,

I am using a Stellaris EKS-LM4F232 Evaluation Kit. I have rebooted repeatedly. The specific error I am getting in CCS is :

CORTEX_M4_0: Error initializing emulator: Error loading FTCJTAG.dll. Please make sure that the file exists (C:\ti\ccsv5\ccs_base\DebugServer\drivers\FTCJTAG.dll)

Which of course it does exist. I did the FTclean. I did an update to the drivers you hyper-linked above. Windows reports the drivers are correct and the Stellaris In-Circuit Debug Interface is working correctly.

I am sure this is something subtle if the working around is working for the rest of the CCS community. I can run CCSv5.0 on my laptop (Windows 7 also). I have been hesitant to update it to ccsv5.2 if that means I can't run CCS on either machine.  It comes up and gives me the ftd2xx.dll error, but clinking OK lets it go off and proceed.

Do you want to link up on Skype and I can share the desktop so you can see what I see and we can probe the depths of windows together? I use this computer for all my engineering work. I mostly use another computer with a Linux distribution for almost everything else. So the machine is not overly cluttered. 

I just confirmed that I can run the qs-logger application and get data off the eval kit through the USB port. I also can use LM Flash Programmer to program the flash on the eval kit through the Stellaris In Circuit Debug Interface which would seem to indicate that the USB drivers are working OK. 

That is all I can think to providefor now.

Hi Ed,

a couple things.  Are the mentioned drivers also in your system32 directory?  Just to double check.  Have you tried a fresh workspace and project?

If you are still stuck after that, then perhaps I can see about arranging a webex.

Hi again Lisa,

Yes the drivers are in system32 dir. I have tried projects that work perfectly on my laptop from the class I took with Scott Bland. I did a complete reinstall of CCS. The only I haven't done it install ccsv5.0 like I have on my laptop to see if that makes a difference. But I was hoping to use the latest (v5.2) and move on.

Ed

Hello Lisa,

I installed CCS v 5.1 and it gives me the ftd2xx.dll error, I click OK and on we go. So CCS 5.1 works and 5.2 doesn't. There seems to be a definite problem in 5.2. Just thought you should know.

Ed

Hi Ed,

this is a known issue, but I am surprised the work around did not do the trick for you.  Let me see if I can get some development colleagues to help dig into this for you.

Best Regards,

Lisa

Hello Lisa:

I am thinking about doing a complete uninstall of all verion and components of CCS, SYS/BIOS, XDC, etc. And do a clean install of ccs v 5.2. What are your thoughts.

Ed

Hi Ed,

it may be worth a try, but you would still need to implement the work around.   If you do try this please keep us informed.

Best Regards,
Lisa

Hi Ed,

thanks for the feedback and patience here.   That is good to know a previous install may interfere.

All the best with development.

Best Regards,

Lisa
