x-linux-ai: recipes-samples: fix CSI DCMIPP camera support
This commit fixes several issues related to the initialization of AI demos when using CSI cameras (OV5640 and IMX335) with the DCMIPP peripheral. All configurations have been moved to an additional setup_camera.sh script and removed from the main demo launcher. https://onedigi.atlassian.net/browse/DEL-9486 Signed-off-by: Arturo Buzarra <arturo.buzarra@digi.com>

Subject: [PATCH] setup_camera_main_isp: fix support for CSI DCMIPP cameras
|
||||
|
||||
This commit fixes the configuration stream for CSI cameras connected to the
|
||||
internal DCMIPP peripheral, including the following changes:
|
||||
|
||||
- Since the /dev/media* indexes are not guaranteed by the Linux kernel and can
|
||||
cause errors, this commit hardcodes the DCMIPP node to be used with the
|
||||
media-ctl command
|
||||
|
||||
- Keep the dynamic check to find the preferred resolution and format for the
|
||||
IMX335 camera sensor. However, use hardcoded values for the OV5640 sensor, as
|
||||
it occasionally reports incorrect values, causing capture failures.
|
||||
|
||||
- Add support for applying horizontal mirror (flip) mode to the camera video
|
||||
image.
|
||||
|
||||
- Print configuration commands to display to the user the settings applied by
|
||||
the script.
