Hi,

you need to rebuild and install the kernel modules:
processors.wiki.ti.com/.../Linux_Kernel_Users_Guide
processors.wiki.ti.com/.../Linux_Kernel_Users_Guide

the kernel modules are installed in the directory "/lib/modules/<kernel-version>/",
where "<kernel-version>" includes also part of last git commit hash (and optionally "-dirty" postfix
if there are uncommitted changes), so it changes with every commit.
(You can check your kernel version from the console with the command 'uname -r' )

Regards,
Yordan

Hi,

Does this happen, when you rebuild your kernel? If so, you could use the top level make file:
make linux
make linux_install
Then rebuild the sgx drivers:
make ti-sgx-ddk-km
make ti-sgx-ddk-km_install

and copy the modules in the /lib/modules/4.4.12-g3639bea54a directory.
Best Regards,
Yordan
