Camera Module V2 ENOSPC Error

[daveyg_71]

I am running a time-lapse script on a pi3 with the new camera module. It will run for about 2-3 hours then crash with the error below. I am running the same script on a pi2 with the original camera module with no problem. The pi2 has been running for about 2 months with no errors.

This is the error:

mmal: mmal_vc_component_enable: failed to enable component: ENOSPC
mmal: camera component couldn't be enabled
mmal: main: Failed to create camera component
mmal: Failed to run camera app. Please check for firmware updates

This is the script:

Code: Select all

#!/bin/bash

DATE=$(date +"%Y-%m-%d_%H%M_%S")

raspistill -o /home/pi/camera_2/$DATE.jpg -t 2000 -vf -w 1920 -h 1080

exec $0

No help??

I tried changing the time from 2 seconds to 20 seconds and still get the error.

Sounds similar to the problem I reported as well:
viewtopic.php?f=43&t=147744

Which distribution and kernel are you using? Did you do

Code: Select all

-> sudo rpi-update

and is you distribution up-to-date?

Code: Select all

-> sudo apt-get update
-> sudo apt-get upgrade

Some debug output would help. As soon as the error occurs, type these commands on the console and copy the output into "code"-Tags:

Code: Select all

-> uname -a
-> sudo vcdbg malloc
-> sudo vcdbg reloc
-> sudo vcdbg log msg

Add the line

Code: Select all

start_debug=1

to your /boot/config.txt, force a sync on the command line:

Code: Select all

-> sudo sync

and reboot.

Now, when the cam crashes, you can also get a log of asserts:

Code: Select all

-> sudo vcdbg log assert

Maybe also useful:

Code: Select all

sudo raspi-gpio get

This is the summary of all the debug data I collected on my Pi A+. Maybe there are some similarities.

Thank you - I hadn't seen this one wherever it had originally been posted.

It does sound the same as Koepi's issue and is being investigated - please watch the other thread.

Was reading the manual.
https://www.raspberrypi.org/wp-content/ ... tation.pdf
Page 4 has ENOSPC error, running out of GPU memory.
GPU code memory leak?
Increase gpu_mem, see if it takes longer to crash?
V2 needs more bytes because it is nearly double the size of the 5Mp.
10bit ADC - 2bytes x 3284 x 2164 x BGGR = 56MB, to do demosaic maths x 3?
168MB? 128MB not enough?
Got Pi2 or 3, make gpu_mem=256?
Got Pi B+ gpu_mem=192

No, there's no memory leak. We're fairly certain we know where it fails in the code from Koepi's issue, but need to work out why the hardware is misbehaving.

Will request mods lock this thread in the absence of any other data.

Locking as requested.
