Hi All

After building an identical project in Creator 3.3 SP2 and 4.0, no component updates (against the Cypress recommendation), toolchain appears identical however the binaries files are quite different. I have perused the release notes http://www.cypress.com/file/318921/download, can't see a reason.

Have I carelessly overlooked details in release documentation, could this be linker order or is this the expected result moving to Creator 4.0?

Many Thanks
Greg

I did not check, but most probably a new GCC version is installed with this version. This might do different optimizations, and code generation, so it will produce different output.

Also, Cypress might have changed the way  how they do component placement and routing to produce better results. This also affects the output.

Thanks for the reply, I also believe the latter in your email to be correct. Building two projects without any components in Creator 3.3SP2 and 4.0 yields the same binary file.

Thanks

Yes Greg,

The placement and routing algorithm is updated.

Thanks
