Tool/software: Code Composer Studio

Hello,

In our application, as part of the software build process, we used armhex.exe(v5.0.4.0) to convert from *.out to Tektronic Hex format. Now we are migrating to an another version of CCS(v6.0.1.00040) which has the armhex.exe( v5.1.6.0). We would like to know whether these 2 versions(v5.0.4.0 and v5.1.6.0) of the hex utility generate the same output.

Similarly please let us know for TMS320F28335 processor, whether hex2000.exe versions v6.2.0.0 to v6.2.7.0 generate the same output.

Thanks,

Sundaram

The format of the hex utility output is the same. But building with different versions of the compiler will cause many low level differences.

Thanks and regards,

Thanks George.

Will these low level differences have any application level/functional impact?

Thanks,

Sundaram

No. For an example of what I mean ...

When you change versions of the compiler, it is often the case the more recent compiler uses more and better optimizations. This causes the compiler generated code to be a bit faster and smaller. And, yes, different from the previous version. But, in terms of the computation performed, it is the same.

Thanks and regards,

-George
