Basler MIPI CSI not detecting

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.
