Raspberry Pi Camera not working

afeser · August 1, 2022, 12:20pm

Hi, I’m trying to run Raspberry Pi camera with RockPi 4 Plus V1.72.
I use debian. I enabled the modules and installed gstreamer, but I the images I get are quite bad looking and almost completely dark.
With this command:
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! jpegenc ! filesink location=test.jpg
I get:

This is not only present in debian, but also in linearo image here -> https://wiki.radxa.com/Rockpi4/MIPI_Camera
When I run this: test_camera-rkisp1.sh
I get this result (green thing is the led of rockpi, without it it’s almost black)

Can this be due to a kernel module?

Edit: the camera is imx219

You possibly need the help from libcamera: https://libcamera.org/

Thank you for the response.

I tried installing the master branch, but it failed(giving some syntax issue in one of the header files), therefore I used an older source from (https://github.com/kbingham/libcamera/commit/e2d00fbcbb1a9b2da50fa2e280817a0de1a7d286)[this link] and installed that one. Finally, it compiled and installed, but now it doesn’t recognize my camera:

I’m a noob and don’t know the relation between /dev/media* and /dev/video*, but I found this one https://github.com/raspberrypi/libcamera-apps/issues/270.

I’m stuck at this point, any help is appreciated

That means your kernel is missing the newer v4l2 io control that libcamera is asking for.
See here:
https://www.kernel.org/doc/html/v4.9/media/uapi/mediactl/media-ioc-g-topology.html
And here:
https://patchwork.libcamera.org/patch/399/

Maybe you need to find a patched libcamera version for your kernel.

To clarify things:
What is the output of:
uname -ra

and what is the sensor?

afeser · August 2, 2022, 8:23am

Currently installed kernel is:
Linux rockpi-4b 4.4.154-116-rockchip-g86a614bc15b3 #1 SMP Mon Jan 10 12:03:08 UTC 2022 aarch64 GNU/Linux

The camera sensor is: imx219

I think in the link you shared they say prior to kernel 4.19; therefore I tried upgrading the kernel to 4.19 from https://github.com/rockchip-linux/kernel/tree/develop-4.19

I also enabled this one from kernel config: Hidden v4l2 configs for GKI (NEW)
but the result is compilation fail:

Maybe you could try this: https://gitlab.collabora.com/koike/linux/-/commit/7d93fa0b60450d1a725a77d81a77ae116f178782

afeser · August 2, 2022, 1:25pm

Ok thanks, I will try this, but I wanted to first finish this kernel thing because after 5 hours of fixing bugs(C compile issues, disabling modules), I finally compiled and installed the kernel. However, I cannot boot anymore; no IP, no display, I can use keyboard but I can only reset. The blue led blinks with some constant frequency.

I disabled these modules:

It could be a kernel config or you missed to enable HDMI and eth in dts. Both things are related.
For this case, you need a USB-TTL serial debug.
BTW, i found some cheap imx219 cameras, just ordered one and i will test it on Rock 3A and see what i get.

I connected using serial, I am attaching logs.

It gets stuck at:

I have missing files inside dtbs/4.19.206-rt87 do you know how can install them?

avaf · August 3, 2022, 11:36am

I don’t know which u-boot you are using.
Read buildroot scripts, it may help.
Looks like you need something like: https://fossies.org/linux/buildroot/board/firefly/roc-rk3399-pc/extlinux.conf

afeser · August 3, 2022, 12:12pm

I don’t know how to check which u-boot I’m using. I’m using extlinux.conf file to change the boot order.

I think the problem is my bad because I assumed rockchip kernel would work on rockpi. It might be the kernel not supporting rockpi4 because there is no such file as rk3399-rock-pi-4b.dtb inside the build directory (but I have tons of dtb file there), it might be this kernel -> https://github.com/rockchip-linux/kernel/tree/develop-4.19 will never work on rockpi4b.

The error is:
** Unable to read file /dtbs/4.19.206-rt87/rockchip/rk3399-rock-pi-4b.dtb

avaf · August 3, 2022, 1:03pm

You need to create a new dtb for your rockpi 4b. rockchip-linux support their evb.
You have a few choices:

create the dtb for your hardware and name it rk3399-rock-pi-4b.dtb
go for a kernel with dts that support the hardware
look for the android kernel and get some inside info there, if i don’t mistake is 4.19.219

good luck

afeser · August 4, 2022, 9:53am

Could you help me creating dtb for the hardware?

The android kernel is 4.19.111 #22 Thu Oct 15 11:16:14 CST 2020 and works without any problems
