Tiva C launchpad ICDI connection

Andrew,

What version of TI Emulators do you have installed? You can find the version in Help->About Code Composer Studio->Installation Details. I tested a clean CCS5.5 installation and I could see some of the errors you described. I then updated to TI Emulators 6.0.14.0 and the Tiva is connecting fine. You can update from Help->Check for Updates.

Thanks,
Mark

Thank you for your reply.

I have a bit troubles with update. I skip it with cancel and try to install new software manually. But i see just Ti emulation updates for Windows in list  of available software. What site should i add to be able to update my emulator?

Andrew,

I have the update site for TI Emulation listed as:

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_ccstudio/CCSv5.1/Updates/Emulation/linux/full

Can you try updating just TI Emulation?

Thanks,

Mark

Okay, done it with your link but still have the same error when try to launch configuration.

Andrew,

Just to confirm, have you run the ccsv5/install_scripts/install_drivers.sh script as sudo?  This is a required step for ICDI to work under linux.

Thanks,

Mark

Andrew,

I believe I see the same problem as you now. I must have been confused with which version of CCS I tested with. I was able to duplicate the error with the new TI Emulation package. It looks like the older version of libstellaris_emu.so that comes with CCS5.5 doesn't have the RPATH set correctly. I don't think you will see the same issue with CCS6.0. I was able to manually adjust the RPATH of libstellaris_emu.so and connect to the Tiva using the following.

cp libstellaris_emu.so libstellaris_emu_save.so
sudo apt-get install chrpath
chrpath -r '$ORIGIN:$ORIGIN/../../common/bin:$ORIGIN/../../../eclipse/xulrunner/' libstellaris_emu.so

Let me know if this works.

Thanks,
Mark

Yes, i made install_drivers.sh after i've installed CCS.

Okay i tried to change RPATH as you mentioned ang got following result:

"new rpath '$ORIGIN:$ORIGIN/opt/ti/ccsv5/ccs_base/common/bin:$ORIGIN/opt/ti/ccsv5/eclipse/xulrunner/' too large; maximum length 83" 

As i understand after some searching about this error, new RPATH can't be longer than original one, isn't it? So i have no ideas how to change it this way.

Andrew,

Did you use the relative path that I listed in the chrpath command? This will make the RPATH shorter than 83 characters.  I'm not sure if chrpath will fill in the absolute path in any circumstance.  My output looks like this:

chrpath -r '$ORIGIN:$ORIGIN/../../common/bin:$ORIGIN/../../../eclipse/xulrunner/' libstellaris_emu.so

libstellaris_emu.so: RPATH=$ORIGIN:$ORIGIN/../../common/bin
libstellaris_emu.so: new RPATH: $ORIGIN:$ORIGIN/../../common/bin:$ORIGIN/../../../eclipse/xulrunner/

Thanks,

Mark

Oh, my bad. I was sure that i need to fill .. with my real path. It helps and now i can launch configuration but still can't connect to the target.

I'm getting : "CORTEX_M4_0: Error connecting to the target: Frequency is out of range."

I've heard it could be if  i didn't change udev rules permission for user but as i suppose i can avoid it starting CCS with sudo. I tried sudo but i see same error.

Andrew,

Can you run install_drivers.sh as sudo again? The rules may have changed with the new emulation update. If you aren't already, you may want to start CCS from the console. There may be error messages in the terminal window that might help. If you don't see any, try running with the console parameter (./ccstudio -console). You can run ccstudio from the ccsv5/eclipse directory.

Thanks,
Mark

You might also want to make sure you are plugged into the "Debug" USB port and not the "Device" USB port on the LaunchPad. Also, make sure the power switch is set to "Debug".

Thanks,
Mark

Sure. I tried to run it again but nothing changes.

Console is available for me even with common start CSS. Everything that shows there looks like:

CORTEX_M4_0: GEL Output:
Memory Map Initialization Complete
CORTEX_M4_0: Error connecting to the target: Frequency is out of range.

Forgot to answer about port connection and switch position - sure i used debug port and same switch position. I've already checked Launchpad - CCS connection on other PC with Windows OS. It was ok, so it should be soft\driver troubles.

Andrew,

I think you are referencing the console within CCS. My suggestion was to run CCS from the terminal (where the messages would be display).

E.g.
mark@host:~/ccs_clean/5.5.0.00077/ccsv5/eclipse$ ./ccstudio -console
osgi>

This should display any error messages that might be occurring with the ICDI drivers after a failed attempt. Can you confirm whether or not any messages appear here?

Thanks,
Mark

Thanks a lot. Your alst link helped a lot.

I'm also getting : "CORTEX_M4_0: Error connecting to the target: Frequency is out of range." problem in ubuntu 14.04 32 bit.. i think ccs6 does not support ubuntu 14.04 32 bit.
Any solution..?
