The resources.yaml file does not exists at the beginning of the db-prepare calls
but the environment wants to read it which leads to the following error:
Preparing artix7 files
============================
Traceback (most recent call last):
File ".../prjxray/utils/create_environment.py", line 62, in <module>
main()
File ".../prjxray/utils/create_environment.py", line 55, in main
environment = get_environment_variables()
File ".../prjxray/utils/create_environment.py", line 37, in get_environment_variables
part_info = get_part_information(db_root, part)
File ".../prjxray/prjxray/util.py", line 44, in get_part_information
"Mapping file {} does not exists".format(filename)
AssertionError: Mapping file .../prjxray/database/artix7/mapping/parts.yaml does not exists
Do not dump the environment during this stage because the XRAY_PART is the only
neccessary information which is set in the <family>.sh script.
