GCC compiler downgrade Issue

[AdithyaJayaram1996]

We want to change the compiler from GCC 10.2 to GCC 6.3 version. Made necessary changes for the same in Toolchain editor window, C/C++ Build settings – Target processor etc.

We see that language.settings.xml file has some reference to compiler version where the build configuration used in the project is mentioned.

From where does it read this information on compiler version? If we try to manually edit this file to reflect the new compiler version, it gets overwritten every time after the build.  How to edit this file, to remove older compiler reference from here.

Also the toolchain id is appropriately updating in the .cproject file with the changes made in the project properties. Please give us pointers as to how to identify the compiler change has happened correctly.

There is an option for choosing GCC version.

Libraries it is needed to rebuilt as well.
