CCS/UCD3138: There has no Linker Files\cyclone_64.cmd & Linker Files\cyclone_64_headers.cmd for UCD3138 of ccs3.3 , Where can I find the files ?

I'm not sure what you are asking for. The files you mention are for the UCD3138064. The corresponding files for the UCD3138 are just cyclone.cmd and cyclone_headers.cmd. Can you see those? '

Are you writing a code for the UCD3138, or for the UCD3138064?

Our EVM codes online now support multiple devices, so they come with several header files for different devices. They are for CCS 6, but the header files should work for both, I think. If you are starting from scratch, I would suggest starting with CCS 6 and a new EVM code.

If you want to convert a code from the UCD3138 to the UCD3138064, I'd suggest using the UCD3138064 header files from a new EVM code and the UCD3138064 Programmer's Manual at www.ti.com/lit/ug/sluuad8b/sluuad8b.pdf. It is designed to explain how to convert from the UCD3138 to the 064.
