Hi All,
I have just followed the instructions for building kernel + sgx modules and the sgx drivers were not installed after reboot.
Going through the /opt/gfxinstall/sgx-install.sh script I found that /sbin/insserv was not installed. After installing the package and reboot all is fine.
Can somebody please confirm that this is the correct solution and that I did not have some other mistake in producing the sd card according to these instruction
