To reproduce:
python workspace_tools/build.py -m K64F -t GCC_ARM --rtos
python workspace_tools/project.py -m K64F -i uvision5 -n RTOS_1
You will see that there is no built RTOS library included, just header files. If I repeat with the following:
python workspace_tools/build.py -m K64F -t ARM --rtos
python workspace_tools/project.py -m K64F -i uvision5 -n RTOS_1
The built RTOS library is included along with the header files.
In the first case, I would expect this to error with something along the lines of:
Library 'RTOS' was not found, please build with toolchain 'ARM'
OR it should just build it for you :)
