Hi everyone,
I'm developing a project in CCSv6 targetting a F28335 Delfino device using the floating-ponit unit. I'd like to share this code to someone else who is still using CCS v3.3 and the same device.
I've installed CCS v3.3 on my PC (same PC where CCSv6 is installed) to try to do this successfully but seems impossible or very tricky. I know that Code Generation Tools are not the same, but I've installed v6.4.2 on CCS v3.3. Does it crash with CCSv6 compiler version?. I'm also doubting if it supports FPU. In order to migrate the project to this older IDE version, I'm copying source, include and library files directly to another directory where I create a new project (Project->New).
Copying this files has no issues, but when compiling it, some undefined symbols appear. I copy them:

Variables are global and defined and initialized in proper files. Don't know why this "undefined symbols" error appears. There are other arithmetic functions which use float words like "cos", "sin" or "sqrt". In this case, I deduce that this intrinsic functions are not defined in this compiler version or something similar. About the rest, I soppose that come from asembler code, but don't know the origin of the error niether how to solve it.
Could you please give me a hint on what should I check, update or how to import the project to CCSv3.3 successfully?
Tanks,
Alex
