i have an issue where my sensors are not saved after a power loss or reboot of my brewpi setup.
my setup consists of
Odroid-x (like a ras pi, little different)
freetronics eleven arduino Uno clone
my onw custom made sheild with the SSr’s to control the fridge and heater.
i had a bastard of a time getting the hex file to flash through the brewpi software, and ended up using xloader (after looking for hours on end to find the hex code) and since then it seems to work well enough
but when there is a power loss or i reboot the odroid, it loses device settings.
i have looked around and tried to re-flash the hex and updated and what not, nothing there helped. and i even ran the command to re-set the eeprom. but that still didnt work.
The problem is that the odroid is sending ‘E’ over serial during the reboot, which is the reset defaults command.
I actually don’t know how you can prevent it from doing that.
so does that mean that a ras-pi will do the same thing? surely not?
as the system is still linux and the script is just python it shouldnt matter the os should it? how can i be the only one with the issue? how come ‘E’ is sent every boot?
The raspberry pi can occasionally send a character, but not every boot.
I am releasing a software update for the Spark later to prevent it from happening (requiring ‘E’ to be followed by \r or \n.
OK, so still not saving sensors upon a reboot. surely there must be a way around this. I have gone as far as having it on a ups so that it keeps going if there is a power outage.
ok, so its done it again.something rebooted, and then lost all settings. i havent checked it for a day and it want heating all day. can anyone help to determine whats causing this?
here is the stderr

I have run an “uptime” command in terminal, and the system has been running for 4 days nonstop. so the odroid isnt rebooting, but something is causing this.

Yes
The duino is powered from an external 12v source. As well as the odroid. I will try another cable tomorrow. I have also gone as far as powering it off a UPS to eliminate spikes and whatnot.
Is there something I can run to see what commands its sending g that’s causing the reset. Seems odd that I am the only person with this issue.
As it runs in python I wouldn’t have thought it would make a difference. Perhaps it does. I had the odroid spate and didn’t want to spend the 80aud to get a pi.
What if I try installing it on a Linus laptop I have. Or would that possibly have hardware issues aswe
