You can’t just grab the newest board manager files. You have to make changes to what gets downloaded with that. Files are missing and so are some needed exe’s. Directories are also named incorrectly. So far nothing will compile on any Artemis board I have.
To clarify the issues im having:
Variant.cpp and .h are missing from SparkFun\hardware\apollo3\1.0.9\cores\arduino\ard_sup\
artemis_svl.exe is missing from /tools/artemis/windows/artemis_svl.exe
The directories in Arduino_Apollo3/variants/ still say blackBoard in the Board manager downloaded files.
The latest SparkFun Apollo3 board package version is 1.0.11 and is available using board manager. It fixes the directory names and thus the missing variant.h problem. I do not use windows so I do not know if it fixes the missing exe problem.
