Hello Tomas Fors,
I assume that you are using QorIQ SDK 2.0.
SDK 2.0 can be built in your local PC without networking environment.
Please download both "QorIQ Linux SDK 2.0 SOURCE ISO" and "QorIQ Linux SDK V2.0 PPCE6500 Yocto Cache.iso"
from Linux® SDK for QorIQ® Processors | NXP , and install them in the same path.
The source ISO includes recipes and source tar balls, the Cache ISO is used to accelerate the building.
Thank,
Yiping
