After you've got the CCS6.1 installing file(exe file), just click on it, and accecpt the terms of the license aggreement.
It is unneccessary to intall all the processors support if you are just using UCD3138 family. So just select the feature what you want.
- Select the ‘digital power’
2. If you would like to have JTAG function, then select ‘Spectrum Digital Debug Probes and Boards’.
Sometime if you found that you've forgot to install some features, there is no need to re-intall the entire CCS6, because it will takes a long time to install it completely. The way to solve this is just click on the exe file and then select the feature you would like to have.
