that's what I did.
There is another problem:
Downloading the latest version of Tivaware create a folder with the following name "TivaWare_C_Series-2.1.0.12573". If a workspace is used with a file containing this path in vars.ini , then CCSv6 always look for a shorter path equivalent to "TivaWare_C_Series-2.1" and the tivaware library are not included!!.
To solve the problem I had to duplicate the folder with the short name.
Can you check this problem?
Thank you in advance for your response,
Sorry for the verified answer, it is a mistake on my part
