Variable references empty selection: ${project_loc}

You may receive this warning in the Efinity RISC-V Embedded Software IDE console while launching the Launch Config Generator:
Figure 1. Project Not Selected Error

Reason:

If you have not selected a project, the RISC-V IDE does not trigger any updates for the ${project_loc} environment variable. The Launch Config Generator needs this variable for internal processing.

Solution:

Select the target project in the Project Explorer before launching the Launch Config Generator.
