Can you say where you have got your version of libcamera from?

It sounds to me like you're running something horribly old, and any even vaguely recent version of Picamera2 will never work.

If you have a spare SD card, are you able simply to install an up-to-date image to test your camera? Can you say why this doesn't work for you? Thanks.

@davidplowman
What is not obvious is the compatibility of the libcamera/picamera2 versions.
For example, currently for me it is OK with the current distributions 3.14 and up to date libcamera distrib.
Should I expect a similar problem if I wanted to try 2.16?

[davidplowman]

We always recommend updating libcamera, rpicam-apps and Picamera2 from apt together, because we always ensure they work together. The root of the problem is that libcamera doesn't have a stable API, though I think things are getting better with some of the version numbering, so that's something we could try to improve.

I think we'd make Picamera2 have a minimum supported libcamera version. We're unlikely to keep newer versions of Picamera2 backwards compatible with older libcameras unless it's straightforward to do and doesn't complicate code paths internally.

[juanmf]

okay, I could start from scratch (before I was tied to kernel 5.13.32) due to the camera driver issue.

Initially it didn't detect the camera again but some of these steps in issue 218 made the trick.

setup for reference, after clean image of :

Ready to start debugging my own app. Thanks!
just a note from your comment on #849 (comment)

request = picam2.capture_request(flush=True)
array = request.make_array('main')
request.flush()

AttributeError: 'CompletedRequest' object has no attribute 'flush'

I'm closing this issue. Thanks for your fast response.

I tried all above changes mentioned in the last comment by @juanmf , yet i am facing the same issue.

I am using a raspberry pi camera V2 NoIR on raspberry pi 4b

With OS as :

It sounds as though you may be running an older version of Pi OS and have tried to install a version of Picamera2 that is newer? I would recommend:

• Upgrade to Pi OS Bookworm if you can.
• If you need to use an older version of Pi OS, only use the version of Picamera2 available in apt, as this will be the correct version for the OS.

@davidplowman , I am using Bullseye OS.

 $ cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
NAME="Debian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

I will try with Bookworm OS once and Update. Thanks for the quick response.
