Raspberry Pi 4 restarting at random
December 29, 2023, 23:32
I have been experiencing RPi4 Restarts at random. Attached are the /var/log/syslog for a boot following the crash.
I would appreciate any guidance you can offer on how to track down the source of the restarts
whats your power supply rating
sometimes there isnt enough power for the pi and it can cause issues unknowingly
another cause is that your sd card might not be fast enough
We have about 65 units deployed on a Custom PCB. I believe the chip's output is 5V1 @ 3A but I will double check. We are only seeing this issue at 1 of 3 locations.
Should be fast enough, yes?
ye
5.1v and 3a is enough
is it set up in a cluster
thats might be a issue
No clusters. These are 1 PCB + 1 Pi mounted to Go-Karts.
oh darn
I appreciate the thoughts. Ruling out is still helpful!
could be a minor case of corupption?
maybe the write was successful but corrupted a tiny bit
There is a string of random characters printed either before the power cycle or after. idk if that's useful info but it's data.
just relised your using dietpi
try reflashing
it seems like the image may have gotten a tiny bit corrupted
so redownload it too
I was going to start with that and realized the plethora of changes required to do it. I think that's a great idea and will be proceeding with a fresh install. I am not convinced that is the source of the issue but...¯\_(⊙︿⊙)_/¯ Ya never know.
yeah
ive never really delt with huge amounts of pi's
you said they were mounted in go-karts
Regretting it over here. While they are nice, they're definitely prototypal devices at best.
yeah
Yea, electric go-karts 🙂
thats rules out power
and since storage is ruled out
it also cant be heat since the rpi to throttle its speed to stay in temp
We were seeing the karts drain too low and causing our boards to power cycle. I am wondering if that had the potential to fry a pi?
no
and what you just said means that the sd cards might be corrupting
Whereby that SD card should not be reused? A fresh SD installed?
fresh install
So the SD itself should be fine?
yes
Brilliant!
its just the data on the sd card is corrupting a lil bit each spike when the go-carts go
What could be corrupted that causes it to run fine except power cycle every once in a while?
ye
We did also get a "RPi Logo" Screen the other day on one of the karts. Power cycling resolved the issue.
that sometimes happens
i did it once
Do you know the cause? Surely corruption would keep it from successfully power on?
it happens if you power cycle too quick
its fine though
What is your experience with the Raspberry Pi?
stable, reliable
and pretty smooth
What I mean is what work do you do with them?
yes
How do you utilize them
just 1 though
for home use
I see. What is your profession?
just a programmer
What languages?
um
javascript
As for this issue, I will consider it answered. I appreciate your time! I will work on the new image and flashing an existing one on 2 of the karts giving us issues right now. See if one or the other resolves it.
all right
Web development, back-end or full-stack?
back-end
TypeScript?
yes
I have a lot of TypeScript in my shop.
I came from a fullstack Java and web background
