AR0521 Camera Firmware Issue

ajsnp · November 22, 2024, 9:08am

Hello dear community,

I am currently trying to set up e-con Systems camera “5MP AR0521 Color” via MIPI CSI interface with a Toradex SoM. My issue is regarding camera firmware errors and missing recognition of the camera by the device.

Here is my setup:

Verdin IMX8M Plus on Dahlia Carrier Board
Yocto-built tdx-reference-multimedia image (OS) with added bitbake layer for camera driver and device tree overlays (as described at First Steps with CSI Camera Set 5MP AR0521 Color (Linux) | Toradex Developer Center)
Image was flashed in Recovery Mode with Toradex Easy Installer
CSI Camera Set 5MP AR0521 Color (V1.0A)

Notably, “tdx-info” outputs that I am on a Verdin Development Board, but I am definitely on a Dahlia Carrier Board. Has this to be specified when building OS image with yocto? I couldn’t find this specification. Also “Toradex Version” is set at “V1.1A” although I am setup with “V1.0A” (intermediary adapter between camera and board).

Also, I am getting error logs in the kernel message buffer (see below). It seems that camera firmware is an issue. As stated at (First Steps with CSI Camera Set 5MP AR0521 Color (Linux) | Toradex Developer Center), I did not interrupt the system upon start up for at least 5 minutes to not corrupt camera firmware.
Is it possible to reset the camera firmware? And if, how?

I2cdetect cli tool reports a signal at position 0x42 for i2c-2 (see below). According to the device tree overlay (cannot post link due to newbie forum restrictions… its at github meta-toradex-econ), I would expect this signal for i2c-3. Is this correct behaviour? Deactivating the device tree overlay removes this signal.

Output of “tdx-info” cli tool:

Hi @ajsnp!

To change the HW model on tdx-info, you’ll need to change the device tree on U-Boot. To do that, you’ll have to stop it on U-Boot by pressing any key while it is booting, then you can use the following commands:

setenv fdt_board dahlia
setenv fdtfile
saveenv

After that, you can reboot the module and it should show the correct HW model on tdx-info.

About the Toradex Version, it is related to the version of your module/SoC (Verdin iMX8MP, in this case) and not to the camera or its adapter.

Going back to the camera issue, the signal reported on i2c-2 is correct. If you check the file imx8mp.dtsi, you can verify that the node i2c3 is “pointing” to i2c2, which is where you’ve found the signal.

About the error, it means that the device could not be found, so I will ask you to verify if it is correctly connected to the board (you can send a picture), and be sure that you didn’t bend the cable, as it could break it. Could you try with another cable too?

Feel free to ask if you have any doubts or issues.

Best regards.

Hello @lucas_az.tx,

thank you for your reply!
I have attached images of the physical hardware setup:

I was able to verify electronical connection of the ffc cable with a multimeter by measuring resistance on the pins. So this seems to be fine and I did not try with another cable since I do not have any at hand. Also, when I connect the ffc cable flipped-alongside, I can not measure low resistance on the pins anymore.
However, I could not yet verify connection between camera and board overall, i.e. from camera module board to dahlia carrier board. Is there an extensive datasheet about this or do you have an idea which pins/parts I could measure resistance on camera and board to verify full connection?

Regarding the “tdx-info” output, I was able to enter boot menu over the serial interface and change board information as described. “tdx-info” now outputs the correct carrier board but the issue remains with same logs in “dmesg”.

Since the camera driver outputs return values like “-6” and “-110”. Is there any documentation on what these return values mean?

Also, hardware clock reports an error (“rtc-ds1307 0-0032: hctosys: unable to read the hardware clock”). Could this be an issue?

Thank you for your support!

Best regards,
Aljoscha Rydzyk

Hi @ajsnp!

We have never faced this issue. This camera is validated, and, as far as we knew, it was working properly.

That said, I would ask you to try to recover the camera because the firmware is probably broken. For that, what we tested before was:

Use a Torizon OS 5 image with the camera overlay: First Steps with CSI Camera Set 5MP AR0521 Color (Torizon) | Toradex Developer Center
Boot the board and wait for the firmware update (5 min+)
Install the new image that you’ll use with the new firmware
Boot the board and wait for the firmware update (5 min+)

Could you please do these steps and verify if it solves the problem?

About the error codes, you can check them on two files in the Linux kernel:

Feel free to ask if you have any doubts or issues.

Best regards.

Hello @lucas_az.tx,

I followed your proposed procedure to try and recover the camera.
After some tries I have finally able to flash TorizonCore 5 (“Torizon OS 5” is not a thing, right?) with added device tree overlay for AR0521 onto the device.
It worked by using TorizonCore Builder with SSH deployment on the already running device (“torizoncore-builder deploy…”). Notably, it did not work using the Toradex Easy Installer (“image not compatible with this module”) but this is probably a different issue.

With TorizonCore 5 installed, the camera driver started properly! Full log to camera driver:

Although, it did not seem as if the camera would update its driver. Excerpt from the log:

When I tried (after at least 5 minutes) to reflash the device with Torizon OS 6 (yocto-built with AR0521 layer), the same old error log appeared like earlier.

Also, on TorizonCore 5, I tried to go one step further and run Weston container following documentation at First Steps with CSI Camera Set 5MP AR0521 Color (Torizon) | Toradex Developer Center.
However, it did not come up healthy. Docker log:

Is there a specific “torizon/weston” version that was proved to work on this setup?
I also tried enabling device tree overlays for HDMI (“verdin-imx8mp_native-hdmi_overlay.dtbo”). Notably, the device tree overlays for DSI-HDMI are not pre-compiled on TorizonCore 5.

From the results, I would assume that the camera works with the provided driver under TorizonCore 5. If with the current driver, it is not possible to upgrade to Torizon OS 6 or 7, I would appreciate support for making video capture possible with TorizonCore 5.
Thanks for your support!

Hi @ajsnp!

Yes, Torizon OS was called TorizonCore in older versions.

Regarding the weston container, I noticed that you used torizon/weston-vivante:3.5, but in our article, it uses torizon/weston-vivante:$CT_TAG_WESTON_VIVANTE, and, if I’m not mistaken, for TorizonCore 5, the variable CT_TAG_WESTON_VIVANTE should be 2.

Could you try to run the container again, please? But using $CT_TAG_WESTON_VIVANTE instead of the version itself.

Best regards.

Hello @lucas_az.tx,

sorry I did not mention that I already the exact command like in the article.
With this command I get similar output.

However, I tried to re-enable the device tree overlays “verdin-imx8mp_lt8912_overlay.dtbo” and “verdin-imx8mp_native-hdmi_overlay.dtbo” which were enabled by default when launching TorizonCore 5 but got disabled when I added the device tree overlay “verdin-imx8mp_ar0521_overlay-1.dtbo”.

With this, I was able to start the weston container and also start a wayland-container, successfully capturing video data and display through HDMI on screen!
That is great so far. So on TorizonCore 5, it seems I can get the camera to work.

For Torizon OS 6, the problem still exists. Presumably, the tested driver at GitHub - toradex/meta-toradex-econ does not work with Torizon OS 6. Are there any efforts taken to make this setup compatible with Torizon OS 6 or even Torizon OS 7?

Thank you for your support so far!

Best regards,
Aljoscha Rydzyk

Hi @ajsnp!

I’ve tested it on Torizon 6, and it worked. Basically, I followed this article, but I had to do some changes that I’ll explain below.

I had to build the image using Yocto as explained here. Then I installed the image on the Verdin iMX8MP.

It is important to say that you should disable the verdin-imx8mp_dsi-to-hdmi_overlay.dtbo overlay to use the native HDMI, which means delete it from overlays.txt and leave the other overlays.

With the image installed, I followed the below steps:

First, I built the gstreamer container using the following Dockerfile and command.

Dockerfile:

ARG BASE_NAME=wayland-base-vivante
ARG IMAGE_ARCH=linux/arm64/v8
ARG IMAGE_TAG=3
ARG DOCKER_REGISTRY=torizon

FROM --platform=$IMAGE_ARCH $DOCKER_REGISTRY/$BASE_NAME:$IMAGE_TAG

RUN apt-get -y update && apt-get install -y --no-install-recommends \
        libgstreamer1.0-0 \
        gstreamer1.0-plugins-base \
        gstreamer1.0-plugins-good \
        gstreamer1.0-plugins-bad \
        gstreamer1.0-plugins-ugly \
        gstreamer1.0-libav \
        gstreamer1.0-tools \
        gstreamer1.0-x \
        gstreamer1.0-alsa \
        gstreamer1.0-gl \
        gstreamer1.0-gtk3 \
        gstreamer1.0-pulseaudio \
        v4l-utils \
        && if [ "${IMAGE_ARCH}" = "linux/arm64/v8" ]; then \
                apt-get install -y --no-install-recommends \
                gstreamer1.0-qt5; fi \
        && apt-get clean && apt-get autoremove && rm -rf /var/lib/apt/lists/*

ENTRYPOINT ["gst-launch-1.0"]

CMD ["videotestsrc", "!", "videoconvert", "!", "videoscale", "!", "waylandsink", "sync=false"]

Command:

docker build . -t gstreamer:test

After that, I ran the Weston container:

docker run -e ACCEPT_FSL_EULA=1 -d --rm --name=weston --net=host --cap-add CAP_SYS_TTY_CONFIG \
             -v /dev:/dev -v /tmp:/tmp -v /run/udev/:/run/udev/ \
             --device-cgroup-rule='c 4:* rmw' --device-cgroup-rule='c 13:* rmw' \
             --device-cgroup-rule='c 199:* rmw' --device-cgroup-rule='c 226:* rmw' \
             torizon/weston-vivante:$CT_TAG_WESTON_VIVANTE --developer --tty=/dev/tty7

Then, I ran the gstreamer container:

docker run --rm -it -v /tmp:/tmp -v /var/run/dbus:/var/run/dbus -v /dev:/dev -v /sys:/sys \
    --device /dev/video0 --device /dev/video1 --device /dev/video2 \ 
    --device-cgroup-rule='c 226:* rmw' --device-cgroup-rule='c 199:* rmw' \
    --entrypoint=bash gstreamer:test

After these steps, you should be inside the container, and then you can run the pipeline with:

gst-launch-1.0 v4l2src device=/dev/video2 ! video/x-raw,width=1920,height=1080,framerate=65/1 ! fpsdisplaysink text-overlay=false video-sink=waylandsink sync=false -v

At this point, you should see the video captured by the camera on your display/monitor.

Feel free to ask if you have any doubts or issues.

Best regards.
Lucas Azeituno.

Hey @lucas_az.tx,

unfortunately, Torizon OS 6 still does not work (original post), even with removing the verdin-imx8mp_dsi-to-hdmi_overlay.dtbo overlay. The camera driver still throws the mentioned errors in dmesg.
On initial start, my overlays.txt looks like this:
fdt_overlays=verdin-imx8mp_hdmi_overlay.dtbo verdin-imx8mp_dsi-to-hdmi_overlay.dtbo verdin-imx8mp_spidev_overlay.dtbo verdin-imx8mp_ar0521_overlay.dtbo
Removing dsi-to-hdmi overlay does not change the result in dmesg (I surely rebooted after each device tree overlay change).

Nevertheless, I can build and start weston and wayland containers but (because the camera driver is not working I suppose), I get gstreamer error:

root@a7e9cd08bd02:/# gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=1920,height=1080,framerate=65/1 ! fpsdisplaysink t
ext-overlay=false video-sink=waylandsink sync=false -v
Setting pipeline to PAUSED ...
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Could not open device '/dev/video0' for reading and writing.
Additional debug info:
../sys/v4l2/v4l2_calls.c(622): gst_v4l2_open (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
system error: Device or resource busy
ERROR: pipeline doesn't want to preroll.
Failed to set pipeline to PAUSED.
Setting pipeline to NULL ...
Freeing pipeline ...

Tried this for video0 and video1 device, there is no video2 device.

Maybe something is wrong with my yocto-built Torizon OS 6 image? I followed the article you posted and use docker. Basically, this command
docker run --rm -it --name=crops -v $PWD:/workdir --workdir=/workdir -e MACHINE=verdin-imx8mp -e IMAGE=torizon-core-docker torizon/crops:kirkstone-6.x.y startup-tdx.sh
only that I execute the scripts commands one by one to be able to introduce the bitbake layer.

I will share my build artifact with you by sending an email to toradex support.
Thank you!

Best regards,
Aljoscha Rydzyk

lucas_az.tx · December 11, 2024, 2:45pm

Hi @ajsnp!

I’ve tried your image, and it didn’t work. I’ll ask you to try again following this article.

First, create a folder and do all the steps within this folder, for example:

mkdir ~/yocto-torizon6
cd ~/yocto-torizon6

Second, prepare the environment for a Torizon 6 (I used 6.8.0) build as you would do it natively. For example, after you’ve configured your git, do the following:

repo init -u git://git.toradex.com/toradex-manifest.git -b refs/tags/6.8.0 -m torizoncore/default.xml

Then you can use repo sync.

After these steps, follow this article to add the meta-toradex-econ layer to your project.

Once you’ve added the econ layer to your project, run the following container:

docker run --rm -it -v /home/<user>/yocto-torizon6/:/workdir crops/poky:ubuntu-22.04 --workdir=/workdir

Now you should be inside the container. You can run:

MACHINE=verdin-imx8mp source setup setup-environment

And you’ll be ready to build the image and deploy it to the Verdin.

After you’ve deployed the Torizon 6, follow the previous steps to run the Weston container and the GStreamer container and pipeline.

I did this, and it worked for me. Please feel free to ask if you have any doubts or issues.

Best regards.
Lucas Azeituno.

Hey @lucas_az.tx,

with these steps, I was able to build an image with working camera driver!
Notably, I ran the “setup-environment” script before adding the bitbake layers because before there would be not bitbake utility.

This is great, thank you for your support.

I am currently figuring out what made the difference to my initial approach. As far as I can see, it is only using the tag 6.8.0 instead of branch kirkstone-6.x.y and/or using the crops/poky:ubuntu-22.04 image instead of torizon/crops:kirkstone-6.x.y. I am figuring that out.

Best regards,
Aljoscha Rydzyk

lucas_az.tx · December 16, 2024, 7:13pm

Hi @ajsnp!

I’m not sure what was wrong with your build, but I’m glad to know that it worked.

I’ll mark my answer as a solution and consider this topic closed, okay? If you face any other issues, please feel free to open another topic in our community.

Best regards.
