CODECOMPOSER: CCS3.x to CCS12 migration

Bonjour Adrien,

I was told that newer versions of CCS have Cygwin, and cp is a linux command that would not be recognised in earlier versions of CCS. However, the error occurs in CCS12, which does have it. 

CCS 12 does come with a subset of cygwin in <CCS INSTALL DIR>/ccs/utils/cygwin, which is used by various tools. Note that the path to cygwin is not known to the CCS IDE project system hence it will not be able to execute "cp" without the full path to it.

A second issue, right now, is how to integrate older versions of DSP/BIOS in newer CCS. The old DSP/BIOS used for this project doesn't have the eclipse plugin folder in it, and I don't know how to add it in the toolchain.

CCS no longer ships with DSP/BIOS. You will need to manually download/installl it. Only DSP/BIOS 5.4x will work with CCS Eclipse. You can download it from:

https://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/bios/dspbios/index.html

I recommend installing it in C:\ti.

Once installed, make sure it is "discovered" by CCS:

Please note that DSP/BIOS has been heavily deprecated in support, especially with CCS 12. IDE Integration is minimal and DSP/BIOS RTA is no longer available.

Thanks

How do I tell the project the path to cygwin ?

I assume you are calling cp as a pre/post build step? You can call cp using an absolute path. I believe adding it to the system PATH would also work.

but not BIOS 5.31.09.16.

You would need at least DSP/BIOS version 5.4x to properly use it with CCS Eclipse. From what I understand, v.5.4x is binary compatible with 5.3x with the main changes being additional "hooks" to allow it to be used with the CCS Eclipse IDE.
