Yes, this is normal expected behavior. The make load target only loads the driver but does not "install" it to be auto-loaded on next reboot. This was a somewhat deliberate choice since /dev/sgx-step should only be used for experiment and not be used on a production machine as it exposes physical memory directly to user space and, hence, compromises system security altogether..
If you'd like, you can always install /dev/sgx-step across reboots, similar to how this is done in install_sgx_driver.sh. I'd also be happy to merge a PR for a similar make install target or so :)

Thanks a lot jovanbulck, that's clear for me! From my point current realization is completely OK. :)
