Hi, Rafael,

The first point: 
Typing the comnand:
d.rast map=xxxx 
you don't load the file. You just display the already imported map from existing mapset
So be sure you files are imported to the  current mapset 
You may check this by the command:
d.list rast (maybe some differences in syntax depending on grass version)

Second: check the projection in your workspace and imported files

Hope it helps

Best regards,

Maria V. Kozlova
