Periods(.) are not allowed in build artifact name in AVR Studio 5.1 beta
When you want to mention the name of the .elf/.a file for a project, you can do it from Project –> Right click –> Properties –> Build Tab –> Artifact Name.
We found that this feature misbehaves when the artifact name had periods (.). There are two known workarounds that will sound a bit obvious
1. Don’t use periods
2. Please download the public release build of 5.1
Have a good time. with studio
