@Serge-V How I can use gpio from debian chroot?

root@Omega-975A:~# uptime
14:47:02 up 5 days, 3:35, load average: 0.11, 0.04, 0.01

I think problem was solved. I have connected omega directly to stabilizer. After it omega hasn't shut down so far.
@ccs-hello Thanks a lot for suggestion.

@Douglas-Kryder USB works with direct connect to omega without any elements. I have checked it with web camera.

Thanks a lot. I will try to improve my scheme by your recommendation.

I am using my own adapter from 2mm to 2.54mm for run Omega.
3.3 V I get from stabilizer LF33CV. Maybe I need some other elements?

Hello.
From time to time my Omega2+ shut down by itself. Some time it can works 2 - 3 days, and some time twice or more by the day. /var/log/lastlog and /var/log/wtmp are empty. How I can detect reason of shuting down? Thanks.

It is amazing. Thanks a lot
