TM4C123GXL launchpad debug issue in CCS5.4 in ubuntu 14.04

Hello,

I have been trying to connect to the TM4C123GXL launchpad with CCS 5.4 installed on my ubuntu 14.04 32 bit laptop. I have been able to successfully build a project and the corresponding binary file. However on asking the CCS to debug, it gives the following error even when the board is powered On with the microUSB connected to the board's DEBUG port:

CORTEX_M4_0: GEL Output:
Memory Map Initialization Complete
CORTEX_M4_0: Error connecting to the target

     Hi, why are you using this old version? Can you upgrade to latest 6.0.1?

     Did you launched install_drivers.sh in the folder installscript? (root privilege required)

    Hi Roberto,

    I tried CCS v5.5 as well. But with that the problems were even worse. I had to make links of some 8 files as mentioned in an another post. But that didn't work either. Besides I think with ubuntu 14.04 and CCS v6 there are numerous other bugs as I have read on the wiki page of TI. Their fixes have also been provided with some packages but only for the 64 bit OS. I am not quite sure if they would work with my 32 bit OS. Hence I am a bit skeptical of upgrading to the latest 6.0.1 version as a solution. Besides the Grace version does have other bugs as I read through the posts related to it.

     Hi, I am using Linux Mint 17 64 bit so I patched all library and launched install script and all work fine. Same for 5.5 release.

     Release are not colliding so both version can run independently.

     see capture of desktop where on left is version 6.0.1 and right 5.5 running on same session.

    Hello Roberto,

    I think the problem is with ubuntu 14.04 32 bit OS and CCS. The TM4C123GXL board I have works seamlessly with CCS 5.4 on WIndows 7 both on the 32 bit and 64 bit OS. I also checked on a machine with MInt 17  64 bit OS and it works with CCS 6. I did run the install_scripts file with root permissions as well. Nothing seems to work.
