Re: #DRAWS oddity, GPS and ALSA headaches #draws
Ok.... now, I did not notice that set of TEMP lines in the output because I

was so focused on the sound device/ALSA and GPS lines. I have heatsinks on the Pi. I have not heard that lack of ventilation of the Pi on a Sunfounder display is an issue even with hats in place... I do not use a wallwart. The Pi has seemed to run happily off the aux 5V USB power out from the Sunfounder 10' display. The display is fed from a 25A 13.9V power supply via 3A fused line from a multi-powerpole type distro panel. No problems in over a year 'til now. I did notice the undervoltage lightning bolt on the X display however. A crappy old DVM says the voltage is 13.77 at the plug to the display with all other devices on the buss operating. I don't have a USB voltage monitor around, so I don't know what the display USB line is putting out but obviously the Pi thinks it is low. The Pi did not seem to be acting sick by itself. Could it be the power source or should I not trust the PI at all? If you think I can trust the Pi, I could always take a different power supply tactic and use the buck supply line in the DRAWs card for the Pi and feed the display from a separate line. Thanks for playing Doc! Jack - KD4IZ

First Pass at your console output. Drivers are loading fine, no software faults, hardware is definitely stressed, gps not working, codec not working Second Pass at your console output. Your RPI is running at over 150F and will soon catch fire if you don't DISCONNECT THE POWER. From vcgencmd throttled=0xd0005 - Temperature limit has occurred - Throttling has occurred - Under voltage has occurred The RPi is currently running throttled & under-voltage Just recently I have seen someone else's RPi start running really hot. Also check your 5V RPi wall wart. Is it warm/hot? /Basil n7nix See embedded below. Jack Spitznagel <kd4iz@frawg.org> writes: Hi Basil,Nope.
