Which branch of meta-toradex and which branch of poky did you use. It
looks like they're somehow not compatible with each other. You'd have to
contact the people maintaining meta-toradex for help really. We require
Yocto Project Compatible layers to have a README file with information
like this, there isn't one in that repository :(.

Its unlikely its line 2 of that file, its line 2 of the do_rootfs
function.

I'd suspect this line:

do_rootfs_prepend () {
     export NATIVE_ROOT=${STAGING_DIR_NATIVE}
}

from trdx-extra.inc

and I'd therefore say this layer is not compatible with daisy or master
since do_rootfs is a python function there. This layer therefore
probably works with some earlier release, hard to say which one for
sure.
