[quote user="AartiG"]This is indeed a bug but I have not been able to reproduce it in CCSv6 beta3 so the bug appears to be fixed. If any of you have this version installed, would you mind giving it a try and confirming it is no longer an issue?[/quote]I confirm that the bug no longer occurs with CCSv6 beta3 - imported the blinky example and changed the compiler version without the additional startup file being added.
[With CCSv6 beta3 also checked that when a new project was created, a startup file was added]
