I`m trying to add driver for specific hardware at startup.
Module file is located at /lib/modules/4.4.0-66-generic/kernel/drivers/misc/
.
Also I've tried /lib/modules/4.4.0-66-generic/kernel/drivers/misc/
.
Module is successfully loaded with command:
$ sudo insmod /lib/modules/4.4.0-66-generic/kernel/drivers/misc/tmk1553b.ko d0=1 t0="MRTAI" nrt=8 misc=1
But couldn’t load module at startup.
Configuration:
OS: Ubuntu 16.04.2
$ uname -a Linux dmitry-ws2 4.4.0-66-generic #87-Ubuntu SMP Fri Mar 3 15:29:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
$ cat /etc/modules # /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line. Lines beginning with "#" are ignored. tmk1553b d0=1 t0="MRTAI" nrt=8 misc=1
Made command:
$ depmod
After restarting computer or service systemd-load-module module tmk1553b
doesn’t appear into loaded kernel modules list.
Diagnostic returns Failed to find module "tmk1553b ..."
error.
$ sudo systemctl restart systemd-modules-load.service Job for systemd-modules-load.service failed because the control process exited with error code. See "systemctl status systemd-modules-load.service" and "journalctl -xe" for details.

What is going wrong?
UPDATE 1:
$ cat /lib/modules/4.4.0-66-generic/modules.dep | grep tmk1553b kernel/drivers/misc/tmk1553b.ko:
modprobe
command returns with success
$ sudo modprobe tmk1553b d0=1 t0="MRTAI" nrt=8 misc=1
UPDATE 2:
Actions I made during driver installation:
$ cp tmk1553b.ko /lib/modules/`uname -r`/kernel/drivers/misc/ $ echo tmk1553b d0=1 t0="MRTAI" nrt=8 misc=1 >> /etc/modules $ depmod $ reboot
This sequence works well on Ubuntu 14.04 but fails on Ubuntu 16.04.2
