For the last week of so my Farmbot was rebooting randomly a few times a day. I tried a new power supply brick and the same thing happened. Today I started the debug and my RPi was not showing up on my network. I rebooted and the status lights on the RPi we solid for power and blinking in a pattern for sync. I then reflashed the Farmbot OS and now the RPi is rebooting continuously. See the video https://photos.app.goo.gl/VoFwVRLaD4WqJw1WA. I’m not sure what next step to be taken.
Hi @tvromero try flashing another
known good SDHC card ?
I got it working. I placed the SD card into a different RPi I had and then the proper booting happened. I replaced the card back into the original RPi and the same no boot happened. I then removed all the attachments to the RPi and booted just with the card and power and the boot worked as expected. I reconnected all the attachments and now the original RPi and original SDcard are all working as expected. I will need to wait a few days to see if the reboots are still happening.
About two weeks ago we had freezing temps here over night, maybe 2-4 hours at 29 to 30F for 5 days. Is the RPi or the farmbot face board susceptible to freezing temps?
In an appropriate enclosure ( where frozen water can’t interfere with the Pi PCB too much ) these temps are not likely to damage the RPi, especially if the RPi is powered On and running.
The PCB has some components spec’ed for 0 … 70 C limits and one may have failed in your case.
I found this RaspberryPi forum thread relevant to your question
I am still having issues with fairly constant reboots which eventually result in the Farmbot not booting completely. The reboots seem to be random over a 24 period but do seem worse at night. I am also getting an undervoltage and throttle issue.
@tvromero Sorry to hear you’re having issues. Can you please email us at firstname.lastname@example.org if you haven’t already and we’ll investigate your issue further and send replacement parts free of charge if necessary.
Thank you for sending additional cables. I have been able to verify that the faulty cable is the power cord from the Farmduino to the RPi. Once that cable was replaced the farmbot has been up and running for over 6 days. I went back to the original power cable today and was not able to get the RPi to fully boot. Replaced with the new power cable and all is working fine.
I appreciate all the help.
