the power source may be ok on paper, but not necessarily in action. One way to verify it would be to connect an oscilloscope to record the voltage. After you shudtown the pi, do you see any strange spikes with the voltage going down and coming back up again. if so, that will restart your pi.HannuT wrote:Nothing on gpios.
Connected are: TV (HDMI), lan-cable and power supply.
Power is Deltaco USB charger (2,1A) so I concider that quite ok power supply.
Oh, you still had the +5V supply to the Pi plugged in? I assumed it was disconnected. The Pi does not have a true "OFF" mode from software, I think the processor (either ARM, and/or the GPU) simply goes into an endless loop that could end in a reboot and restart if there is anything that interrupts it, possibly including some random ESD event, signal from TV, AC line power fluctuation etc.HannuT wrote:Ehe ehe Kriss...
That is what I do now so I do not need to wake up in the middle of the night when the Pi wakes up the TV... Disconnecting power is the only way to keep Pi from booting on its own.
one of the RF switched sockets would also do the trick (allowing you to turn it on and off without getting up)Joe Schmoe wrote:It just occurred to me that the best way to handle this problem (handle, not fix)
would be to get a normal electronic timer - the kind used to turn Christmas lights on and off at set times.
I don't know about you, but I have lots of these devices laying around my house...
Then you could set it to turn power off when you don't want the Pi to be on.
Note: This solution actually addresses the "I want my Pi off for some fixed, known part of the day, and I want it on at other fixed, known times." I.e., say you want it on from 7 AM to 7 PM. Then this little timer doodle is the perfect solution (*). I don't know if this is exactly the OP's situation or not...
(*) Of course, you program the Pi to do a "init 0" at, say, 6:55 PM. Then the power gets cut at 7, and comes back on (rebooting the Pi) at 7 AM.
Huh?I'm not sure if this would work by what not leave the Pi completely On, turn off the TV but leave the Pi running.
re-reading the original post, he has already tried that, which I missed somehow.Joe Schmoe wrote:Huh?I'm not sure if this would work by what not leave the Pi completely On, turn off the TV but leave the Pi running.
