Title: Permanent Restart
Post by: Balle on June 01, 2014, 08:20:56 PM
Hi,

During the weekend I was wiring up my ATXRaspi Rev2 and experienced some issues.
1. After wiring it up and finally doing the power connection, the Raspi was directly starting (without pressing the button).
2. After 10-20 sec the lights on the Raspi went down for about a sec and the Raspi was restarting. This will go on forever.
I have measured the power output of the ATXRaspi and I noticed a power drop below 5 Volt when the Raspi does down.
Without the ATXRaspi it is running fine.

Thank you in advance for your support,

Balle

Please be sure to have the software part installed and wiring done correctly. That's what I would check first.

Hi Felix,
I have the wiring rechecked and software reinstalled. Everything OK now. Don't know what the issue was, but that doesn't matter.
Thanks for this great product and your support.

Hi,

I was wiring up my ATXRaspi Rev2.8 and experienced some issues.
1. After wiring it up and finally doing the power connection, the Raspi was directly starting (without pressing the button).
2. After 10-20 sec the lights on the Raspi went down for about a sec and the Raspi was restarting. This will go on forever.


Thank you,

Bryan,
Not knowing what switch you used, Is it possible you are wired to the normally closed contacts instead of normally open?  It could also be too much solder on your header pins which could cause a short under the plastic separating the pins.  Possibly disconnect everything and ring out the switch pins.

Also, if you could post some pictures it might help.

bryan321,
What type of switch are you using?

I guess I should have added, is the switch momentary?

Did you try and re-load the software like mentioned above?  Felix or others will have to help ya if it's a software issue. You happen to meter the switch, it's open correct?
Title: Re: Permanent Restart
Post by: bryan321 on November 03, 2018, 08:46:01 PM
yes i re-load the software and the switch is open.

What are the ATXRaspi LEDs doing all this time?
What is the output in the console reporting (specifically coming from the ATXRaspi script)?

The LED is Green and then it starts up. Then I get the Red Trigger Light and it shuts itself down and then restarts. Sometimes it shuts itself down, but does not restart.

Where would I find the Console Output Reporting?

On the console output, at the end of the booting wall of text.
Or do you boot into a desktop?
Title: Re: Permanent Restart
Post by: bryan321 on November 03, 2018, 09:29:35 PM
No I'm not booting into a desktop. I have RETROPIE and at the end it says Trigger Detected or something trigger. It happens so fast you can't read it.

Hmmm. Not sure what's going on.
Try setting it up on a clean latest raspbian, it is known to work on that.
Otherwise in the interest of saving time you're welcome to send it back and I will take a look at it if you want.

The guide, video and all resources in this forum pretty much explain how it's supposed to work. You can test the ATXRaspi board by itself to verify it works, again I will point you to the guide for that and I wont repeat it here. It's all well documented and the board has a very simple principle of operation and uses the 2 feedback pins to determine the state of the Pi and to trigger a reboot/shutdown. The shutdown script has to be installed and working properly. Boot into your console to ensure it is running.

The ATXRaspi will not issue restarts/reboots without a user button press. So I suspect those random restarts are caused by something else. Your wiring looks OK but I've seen shorts between pins caused by improper soldering and corrosion. I would really double check that and make sure there is no residue between any of the atxraspi soldered pins.

Just had this thought:

If the feedback pins are not correctly wired to the Pi or they are flimsy, those GPIOs on the Pi side can float around randomly, causing the shutdown script to issue random restart/shutdowns, which could explain the behavior.
Double check those connections, maybe with the Pi off check for continuity.
Booting in console would allow you to see what triggers the reboot/shutdown, if they are caused by the SHUTDOWN pin or not.

I discover a short in the board. I disconnected the led and the button. While  holding it with my finger it turn it on and then triggered a shutdown. So just ordered a new one. I didnít I could send it back to be looked at .
