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 ```auto [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. ```auto from pypylon import pylon tl_factory = pylon.TlFactory.GetInstance() devices = tl_factory.EnumerateDevices() for device in devices: print(device.GetFriendlyName()) ``` ---

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? ---

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](https://github.com/SolidRun/linux-stable/tree/lf-5.10.72-2.2.0-sr). I am still working on fine tuning the memory allocations for the 1GB SOM variants. ---

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? ---

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. ---

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 ---

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](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: [Feb 9 11:14] : Unregistered all entities [+0.061861] basler\_camera\_driver\_vvcam: loading out-of-tree module taints kernel.
