Cam utility is not listing the camera in RPI 3B+ #52

Closed savidha777 closed 2 years ago

savidha777 commented 2 years ago

Hi

In RDK-C RPI camera image, Added "dtoverlay=imx219" in /boot/config.txt file and rebooted the system.

Once system rebooted , tried to list out available camera in RPI system with 'cam -l' utility.

But it is not listing the camera. After the some prints binary is hanged.

But able to list out camera in RPI system with oldest libcamera revision

Any dependency or configurations are needed to list out camera in latest libcamera source code.

Are you running an up to date kernel and boot loader firmware (from RPi) as well?

Used latest libcamera revision : https://github.com/kbingham/libcamera/commit/8b02645845bf404fba83910818b285b652f14f89 (20Jul2022)

This isn't the latest libcamera revision. The master branch currently has 74ab3f778c848b20cbf8fe299170756ff6ebab1a is already a fair few commits on. It's worth checking the latest master which has some updates from RPi for camera stability - but I don't think in this instance it will have much effect.

Observing same hang issue with this latest revision 74ab3f778c848b20cbf8fe299170756ff6ebab1a.

Currently we are using below kernel and boot loader version for RPI

Kernel: SRC URI : git://github.com/raspberrypi/linux.git Branch : rpi-5.4.y

Boot loader: https://github.com/raspberrypi/firmware/archive/1eb8921ae7158249894f89e8bb6c4bfb04ec7377.tar.gz SRC_REV : 1eb8921ae7158249894f89e8bb6c4bfb04ec7377 (19Nov2020)

Requesting to share libcamera required RPI kernel and boot loader version.

Requesting to share libcamera required RPI kernel and boot loader version.

That's really a question for Raspberry Pi ... and perhaps should be asked on their forums.

Alternatively, could you move this issue to https://github.com/raspberrypi/libcamera please?

savidha777 commented 2 years ago

Okay

savidha777 commented 2 years ago

Is this hang issue is really based on RPI kernel and boot loader version or some thing else creating the issue?

any idea on this...

kbingham commented 2 years ago

I don't know yet. It sounds very Raspberry Pi specific to me ... hence lets move it to RPi.

kbingham commented 2 years ago

Closing here, we can reopen if it's not RPi specific.

savidha777 commented 2 years ago

Hi,

We are observing same hang issue with upgraded rpi 5.15 kernel as well.

please find below used libcamera revision and rpi kernel revision.

libcamera : 685da13d02c01ed0a2bb7080f95b7ac56e80f221 (21Sep22)

RPI Kernel : rpi-5.15.y version - 5.15.74 revision - dbd073e4028580a09b6ee507e0c137441cb52650 (Sep22)

Based on the analysis, Observing the hang issue in below API calling

device_enumerator.cpp addDevice() -> devicesAdded.emit();

Please find this attached break point output 04Nov22_cam_utility_HangIssue.txt

Thanks!!!

Please make sure you have all logging enabled too.
