adam Posted May 11, 2017 Share Posted May 11, 2017 The device gets unbearably hot as soon as it gets turned on, after ~30 seconds the Ethernet ports start to flash and the red light flashes for ~.5 of a second. I'm assuming it's toast, right? Link to comment Share on other sites More sharing options...
jhpadjustable Posted May 12, 2017 Share Posted May 12, 2017 Could be a bad/insufficient/old power supply, bad/counterfeit/mis-inserted SD card, bad/wrong/corrupted image, .... you really should view the serial console[1] to see if there's any useful message or any legible output at all. If you must fly blind, first try rewriting the SD card, making sure you're using the correct stable image for the board and verifying that it was downloaded, extracted, and written to the card properly. [1] See http://lucsmall.com/2017/01/19/beginners-guide-to-the-orange-pi-zero/ (read the note on the USB-to-serial converter voltage level before the "Software requirements" heading, then skip to "Alternative strategy, using USB-to-serial converter") 2 Link to comment Share on other sites More sharing options...
adam Posted May 12, 2017 Author Share Posted May 12, 2017 @jhpadjustable Tried reflashing the SD and another power supply, no die. I can't get the serial output without cracking out my trusty ol' arduino I had the device working for two days (on and off), I left it running over night, so I think the SoC overheated and shorted itself internally, ordered another one anyway.

hillz Posted May 13, 2017 Share Posted May 13, 2017 I also had the same problem for me the culprit was the LAN cable faulty. With pi zero you really have to apply a fan or your board will get really hot about 80C and it'll restart frequently Link to comment Share on other sites More sharing options...
kisio Posted May 13, 2017 Share Posted May 13, 2017 What are You doing with it? Did You try h3consumption? Mine runs for 3 weeks and barely gets warm. Never over 50. Wysłane z mojego LG-D855 przy użyciu Tapatalka Link to comment Share on other sites More sharing options...

Overheating has been associated with insufficient power supplies. Even in the black box with no heatsink, I have never exceeded 62°C when powering the device from a decent adapter.

It's in a really tiny enclosure (picture) providing no airflow with just a heatsink glued to the SoC. Which OS are you running on your Zero?

I had setup a WiFi access point with it. it wasn't going to be an actual router, I was just testing my Android App with it pushing config files ect. I am unable to even boot the device, it heats up without an SD card too.

I'm using the standard quick charger from my S7 edge with a decent microUSB cable, it shouldn't be a problem. I've also tried it with my computers USB ports (max 500mA). Maybe my unit just had a defective SoC. 8 hours ago, tkaiser said: Which OS are you running on your Zero? I was running the legacy kernel listed on the Orange Pi Zero page. I can't measure the temperature of the SoC however if I place my finger on it and apply power it gets unbearably hot within ~2 seconds. Link to comment Share on other sites More sharing options...

Sounds defective. There's a testpoint called 1V2C on the board. You should measure voltage between this testpoint and ground. Should be either 1.1V or 1.3V and if it exceeds the latter voltage regulation on your board is broken. Link to comment Share on other sites More sharing options...

I am running openwrt and using the built in wifi as an AP, perhaps that's what causes the temp to go really high. Anyway I just found out there's an already available image of openwrt in the orange pi website http://www.orangepi.org/downloadresources/orangepizero/2017-05-05/orangepizero_f76137cbe2e0f38f8d5b32c.html Link to comment Share on other sites More sharing options...
