I have finally had to to revisit this issue and help you replicate it. I was able to fix it by adding copying the xml.gz file from the Atmel Arm Cortex BSP from VisualGDB website and added it to the ATMEL Start BSP folder, and then added the path to it under the MCUDefinitionFile property of the BSP.XML for the ATMEL Start BSP. I also added it to the CMakeLists.txt usingĀ HWREGISTER_LIST_FILE same70b/DeviceDefinitions/SAME70N21.xml
I’m not 100% sure if both places are necessary or not, but it works now so I’m happy. Hopefully that will help anyone else trying to fix this issue as well.
