You are using a small embedded device; it will be necessary to confirm with your device manufacturer the compatible operating systems. On embedded devices the manufacturers provide the drivers, the issue with the video software and network might be related to compatibility.
Now, in regards to log errors, I suggest you to get in touch with your Linux OS support and request the steps necessary to follow in order to get them.
Hi Mike C,
We didn't used an offical linux distribution but built Linux from Yocto-1.5( poky-dora-10.0.0.tar.bz2 ), kernel was replaced by 3.8.0. For drivers, most of them are from Ycoto-1.5, except MIPI CSI driver from Fedora 18, and video driver is Intel_BYT_FC18_CED-LITE32_V36-1-23_RC_2014-09-03_3790.tar from an Intel FE.
