I just upgraded my GCC toolchain to 6.3.1. (was 5.3.1). It was comparable simple because the directory structure found in https://developer.arm.com/open-s... just needs to be replaced by the one that was on my harddisk in the ATMEL installation directory.
When I build my project I still get the message 'Invoking ... 5.3.1'. This is just a text message because when I compile in verbose mode I can see that the project is compiled by the new toolchain. The 'Invoking ...' message comes from the Makefile. However, I couldn't figure out how to change this. Does anyone know how to do this?
Additionally I find out that in my project properties dialog box the entry 'Toolchain->ARM/GNU common->General' still has the old default paths. I couldn't find a way how to change this as well. In the AS7 help pages this entry is simply ignored. Any hint is welcome.
