Change the cameras or camera parameters (YOCTO Linux PD16.1.0 and higher)
At the moment is only the VM-010 camera series supported. The driver is compiled in the BSP and will be loaded at the boot sequence.
You can only change the color type of the camera between "color" and "monochrome".
If you need a higher resolution or more than one camera, we recommend using a phyCORE-i.MX6 or phyFLEX-i.MX6 SOM.
For more information see on FTP:
ftp://ftp.phytec.de/pub/ImageProcessing/phyBOARD-Segin-i.MX6UL_linux_PD17.2.0/
The configuration in the config-expansions file must match with the camera models that are connected to the camera interfaces.
Note that model, interface type and I²C-addresses must be set correctly. Otherwise the camera(s) are not working.
Please check, if the correct camera model is set in the config file. If not, please follow the steps below to set the appropriate configuration.
Changing the setting of the camera-bootarg parameters
Depending on the camera there has to be set a corresponding entry in the bootloader Barebox.
At the moment you can only change between the -COL (color) and –BW (monochrome) versions of VM-010.
To change the device-tree use the Barebox environment:
- type 'nv linux.bootargs.mt9v022="mt9v022.sensor_type=color"' <enter>, for color version
- type 'nv linux.bootargs.mt9v022="mt9v022.sensor_type=mono"' <enter>, for monochrome version
- type 'saveenv' <enter>
- type 'reset' <enter>
After login, change into the directory: \gstreamer_examples\..
cd gstreamer_examples <ENTER>.
Now you can start working with the GStreamer demo-scripts. Detailed information about the GStreamer examples can be found in the phyCAM-Manual L-748.
