Using TI ARM compiler v5.1.5 installed in CCS 6.0.0.00190 a problem was found with the debug information produced by the compiler. Due to the problem, wanted to install older version of the TI ARM compiler to see if the problem existed in older compiler versions.
Using the CCS 6 "Install New Software" screen un-ticked the "Show only the latest versions of available software", and the screen then allowed me to select installation of TI ARM compiler v5.1.0:
However, when select "Next" CCS then displays an error saying it can't complete the installation of ARM compiler tools v5.1.0 because a "a newer version is already installed". The "Next" and "Finish" buttons are greyed-out and are unable to install the ARM compiler tools v5.1.0:
Since each version of the compiler is installed in a separate directory, why is CCS 6 not allowing an older version to be installed?
Notes:
1) From memory CCS 5.5 didn't have this issue.
2) A separate thread was raised on the TI C/C++ Compiler - Forum about the problem with the debug information from the TI ARM compiler - this thread is only about why CCS 6 doesn't allow installation of older compilers.
