camera not enabled

[guy111a]

Hello

I got a bananaPI M2 Zero and got the recommended camera module. Trying to follow this manual, downloaded the image, it is working.

when trying to init the camera i get this: pi@banana:~$ sudo media-ctl --device /dev/media1 --set-v4l2 '"ov5640 2-003c":0[fmt:YUYV8_2X8/1280x720]' Failed to enumerate /dev/media1 (-2) pi@banana:~$ sudo media-ctl --device /dev/media1 --set-v4l2 '"ov5640 2-003c":0[fmt:YUYV8_2X8/640x480]' Failed to enumerate /dev/media1 (-2) pi@banana:~$

I activated all io of the board (i2c etc') no help.

From DMESG: pi@banana:~$ dmesg | grep capture -a3 -n5 109-[ 1.192517] libata version 3.00 loaded. 110-[ 1.192815] usbcore: registered new interface driver usbfs 111-[ 1.192863] usbcore: registered new interface driver hub 112-[ 1.192910] usbcore: registered new device driver usb 113-[ 1.193053] mc: Linux media interface: v0.10 114:[ 1.193087] videodev: Linux video capture interface: v2.00 115-[ 1.193217] pps_core: LinuxPPS API ver. 1 registered 116-[ 1.193225] pps_core: Software ver. 5.3.6 - Copyright 2005-2007 Rodolfo Giometti [email protected] 117-[ 1.193245] PTP clock support registered 118-[ 1.193965] Advanced Linux Sound Architecture Driver Initialized. 119-[ 1.194992] NetLabel: Initializing pi@banana:~$

Thank you.

I'm not sure what's causing your problem. It looks like a hardware problem. Are you 100% sure that you have the OV5640 camera suitable for the BananaPIi-M2? There are OV5640 cameras with opposite wiring.

I downloaded the image again and tested it on my BPi. No problems here. I have listed a number of diagnostic screens below.

Thank you for your comment, i was following the next : https://github.com/Qengineering/BananaPi-M2-Zero-OV5640 And bought the camera mentioned there : https://nl.aliexpress.com/item/32660117929.html

The one that I got looks the same as the photos by the manual and the aliexpress dealer.

Let me test the things you show in the screen shots.

Thank you

Guy

In that case it should (eventually) work; you use the same hardware.

I experienced this problem with the same board and camera. Initially, on first boot I successfully used the camera following the instructions in the readme. I then updated all packages in aptitude and rebooted. Afterwards, /dev/media1 and /dev/video1 were no longer present.

pi@banana:~$ v4l2-ctl --list-devices
cedrus (platform:cedrus):
	/dev/video0

pi@banana:~$ ls /dev/video*
/dev/video0
pi@banana:~$ ls /dev/media*
/dev/media0
pi@banana:~$

After this I restored a fresh image and the camera worked once more. Looking at scrollback from my earlier session, I noticed that one of the packages that was upgraded was linux-image-current-sunxi. I suspect that doing so caused my problems, although I haven't confirmed. If appropriate, I would suggest putting a hold on that package in aptitude.
