Power on and off

Capeman

Ok, so i bought the ebay power button that was mentioned above. There is one comparison that i can make to the Petrock Powerblock.

When the petrock powerblock shuts down, it seems to run a longer process, I am not sure what this process is or why it's needed (i'm guessing its a script that cleanly exits emulation station so that all xml files are saved? Maybe a dev can elaborate on this). But it takes upwards of 20 seconds to fully turn off.

The ebay IR power HAT seems to simply send a SUDO HALT command to the pi, which supposedly safely shuts it off, but does so in a pretty abrupt way. I am not sure if this is safe for a retropie installation, considering it's a software shutdown that probably instantly crashes out all running apps, it's probably still safer than pulling the plug because nothing will be "interrupted" but it seems odd that it shuts off this quickly.

This seems to be the same speed shutdown as the single button GPIO method detailed in the video by ETAprime in a previous post. Can anyone elaborate on if this is a safe way to shutdown?

@Capeman As far as I know... A HALT command in Linux does not kill any process. It basically tells it to stop whenever it is safe to do so. It may or may not have finished doing what it is doing but it is sort of a semi-forced end to on-going processes. I'm sorry that is such a vague answer but you will probably get another 20 or so conflicting answers! That's Linux!

Hmmm, it appears the service for this HAT is causing my Pi to heat up for some reason. I tried to remove the powerblock driver from my spare installation before putting on drivers for this HAT, there is probably something conflicting.

Must be a conflict on mine, i pull the heat icon after about 15 minutes of leaving it on, i'll try it again on a fresh install.
