<div dir="ltr">My guess is that the I/O pin on the Pi was accidentally connected to the common pin of the switch. Flicking the switch then caused 5V to be directly connected to the Pi's IO pin that was being driven low at the time.</div><br><div class="gmail_quote"><div dir="ltr">On Mon, Sep 3, 2018 at 12:18 PM Volker Kuhlmann <<a href="mailto:list57@top.geek.nz" target="_blank">list57@top.geek.nz</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I'll bring some ARM devices with me.<br>

For boot loader remote debugging I set up 2 RPis, with one switching the<br>
power of the other. I used a 3-position slide switch, for off, on,<br>
I/O-pin, to switch the gate of a p-channel MOSFET. This turned out to be<br>
a bad idea. Why? ;-)<br>
First prize of a completely dead RPi to the person with the correct<br>
answer, haha...<br>
