Hi,

So if I read the above correctly, you were able to create a new x86-64
bsp using yocto-bsp and build and boot the minimal image?

If so, then the below should also work - at the point you are in the
creation script, there's nothing arm-specific yet.

If not, did you source oe-init-build-env first?  Or do you have some
kind of network problem?

I can't think of anything else - I just tried the same thing here and it
worked fine.  Let me also try the same thing but using the denzil
tarball (using git denzil branch), which is what I assume your using?

Thanks,

Tom
