I created a C++ Project with the Atmel Studio 7 using a Atmel START configuration file. I described the step-by-step procedure in an article at Portal Embarcados : https://www.embarcados.com.br/iniciando-um-projeto-c-no-atmel-studio/ (the article is in portuguese)
The project is compiling very well.
My hardware is one SAMD21 M0-Mini and I'm using one JLink-Edu as debugging tool.
After I have started the debug section, the debug didn't works appropriately. Bellow there the print screen of the debug section.
For sanity check, I created another project with the Atmel START and imported into AS7. The debug worked very well.
I'd like to know what is going on...
