Basler MIPI CSI not detecting

NXP i.MX8M Plus
1

Hello,

I am trying to get a Basler Dart daA3840 CSI Camera connected and working with the MIPI CSI port on the iMX8 M Plus SOM. I have built the imx-image-full in yocto using Gatesgarth successfully. At runtime I am receiving some errors coming after loading the basler_camera_driver_vvcam kernel module

[    7.406198] i2c_transfer() failed: -6
[    7.409890] basler_read_register_chunk() failed: -6
[    7.414791] basler_read_register() failed: -6

When I try to run one of the simple examples with pypylon The code is unable to detect any camera instances. Here is a snippet of what I am running. Nothing is printed in the output.

from pypylon import pylon


tl_factory = pylon.TlFactory.GetInstance()
devices = tl_factory.EnumerateDevices()
for device in devices:
    print(device.GetFriendlyName())

I have also attempted to access the camera through OpenCV and I am receiving the following dimes prints

That BSP contained a bug in the Basler device connected to the MIPI CSI port used on the SOM. I believe that is fixed in the most recent BSP. I will post a link to a test image. Sorry about the confusion.

Sounds great. If you could also provide a link to the fix I can patch it in. Thanks!

Checking in to see if you have discovered a pending fix in the BSP. I saw some commits regarding the MIPI clock speed in the 5.4.x 2.3.0 BSP but no references to the 5.10 branch.

Hello,

I still have an issue with Basler Dart daA3840 CSI Camera with the latest image.
Where I can find a fixed image?

7

This has been fixed in our latest Yocto BSP that will be released this week. The initial kernel code has been posted here, GitHub - SolidRun/linux-stable at lf-5.10.72-2.2.0-sr. I am still working on fine tuning the memory allocations for the 1GB SOM variants.

8

Thank you

9

Can you share tunning memory results for 1GB memory?
I guess you are talking about VVCAM, ISP_REG_BASE and ISP_REG_BASE in version.h?

10

Those settings are all specific to the device and won’t change. I am mostly working to tweak the Linux kernel settings for CMA memory allocation that are used for allocating large contiguous buffers that are used primarily by the multimedia subsystems.

11

My 1GB Module perfectly works with the camera. It seems the configuration was done correctly. Can you point me to the source tree with these settings?
Thank you

12

This is done in the device-tree file for the board. You can see the memory node that is dedicated to cma.

Hi,

I’m trying to bring-up the Basler Dart daA3840 CSI camera with iMx8 MP solidrun board. (https://wiki.analog.com/_media/resources/eval/user-guides/eval-adtf3175-nxz/som_carrier-datasheet.pdf)

The camera has been probed successfully but I’m not able to capture the frames. Also v4l2-ctl command line tool gives error and not able to detect the frame format.

Here is the dump of dmesg when camera driver is probed:

Which mipi CSI connector do you have the camera connected to? Also please include the output for media-ctl -p

15

The camera is connected on csi1 interface.
