Hello @gylmd1 ,

I have a couple of clarifying questions. Could you please tell us what exactly are you trying to build? Have you installed one of our BSP images from the Toradex Easy installer, that ships along with the modules? or perhaps you are trying to build a own custom image with Yocto?

BR, Janani
