CAM500 & Fire3 : ion issue

Moderators: chensy, FATechsupport

I've tried the nanocams program provided with the armhf release of friendlycore, namely s5p6818-friendly-core-xenial-4.4-armhf-20171212.img ... and here is the output of the program :

To run Qt5 demo, type "qt5demo" at the command prompt and then hit the enter key.
To play a video demo, use command "sudo gst-player /home/pi/demo.mp4".

open /dev/ion failed!
E/542: failed to ion_open, errno = 2

I tried twice to format/reload the image, but each time I boot the device, I can see some kernel modules failing :

Code: Select all

[ OK ] Started Remount Root and Kernel File Systems.

The advises systemctl command issues these infos :

What are those 'v' and 'n' modules, I have no clue... Are they related to ion ? :?

Did someone actually manage to have the nanocamps util running, and if so, under which Fire3 image ? :cry:
And by the way, why are the /dev/ion dependencies missing on the OS image ?
