you could go to wifi settings in the console and check to see there is only 1 instance of a network to connect to-namely that router. cause if that network [the router ip] is not the only one then as soon as it drops off the omega2+ will connect to the next available network with highest priority. like if your cellphone is a hotspot. i wonder if it's possible the omega2+ is connecting to your neighbors router and waiting for a password even though it is not on the list.
Being an apt-get and yum guy, I thought the "search" was actually searching repositories. Turns out I guess not, because I basically stumbled across http://downloads.lede-project.org/snapshots/packages/mipsel_24kc/ which has gobs of stuff, including gphoto2, the libraries, and camera drivers already to go. Installed, working, awesome.
Hopefully this helps an experienced linux person but a total noob to embedded systems like me.
power OFF your Omega2+
press and hold down the Reset button (the momentary push button between the FW_RST pin and the +3.3V)
switch the Omega's power ON
and after this you should see the UBoot menu on the serial console...
@Zheng-Tean i was thinking of placing the omega2 in the breadboard adapter and use wires to link all pins except the 2 i2c pins to the arduino dock. never got around to trying it or even if the idea is so stupid it's a waste of time.
You shouldn't need to do anything with a .bin file to fix a jffs2 error, unless you've flashed a .bin file for the wrong board (2 vs 2+, or worse original Omega), or you used one of the bad .bin files that were published months ago (and hopefully withdrawn??)
