AM62A7: OX05B1s camera on AM62A SK EVM results in error with STREAMON 32 (Broken pipe)

Tool/software:

Hi,

I try to get the example from the AM6xA ISP Tuning Guide running and already get stuck at the verification of the functional operation.

I'm using a SK-AM62A-LP where the OX05B1S camera driver was integrated.  For me the query of the device looks ok

root@am62axx-evm:~# v4l2-ctl --list-devices
j721e-csi2rx (platform:30102000.ticsi2rx):

The setup of the adapted Gstreamer pipeline does not work as expected but results in the following output:

I'm a little lost with the error message, it seems not to be a problem of the settings of the camera.

Thanks in advance.

    Hello,

    You'll need to setup the media entity formats and the routes:

    # Set CDNS CSI Bridge
media-ctl -R '"cdns_csi2rx.30101000.csi-bridge" [0/0 -> 1/0 [1], 0/1 -> 1/1 [1]]'
media-ctl -V '"cdns_csi2rx.30101000.csi-bridge":0/0 [fmt:SBGGI10_1X10/2592x1944 field:none colorspace:srgb]'
media-ctl -V '"cdns_csi2rx.30101000.csi-bridge":0/1 [fmt:SBGGI10_1X10/2592x1944 field:none colorspace:srgb]'

# Set j721e-csi2rx routes
media-ctl -R '"30102000.ticsi2rx" [0/0 -> 1/0 [1], 0/1 -> 2/0 [1]]'
media-ctl -V '"30102000.ticsi2rx":0/0 [fmt:SBGGI10_1X10/2592x1944 field:none colorspace:srgb]'
media-ctl -V '"30102000.ticsi2rx":0/1 [fmt:SBGGI10_1X10/2592x1944 field:none colorspace:srgb]' 

# Set video node formats
v4l2-ctl -z platform:30102000.ticsi2rx -d "30102000.ticsi2rx context 0" -v width=2592,height=1944,pixelformat=BGI0
v4l2-ctl -z platform:30102000.ticsi2rx -d "30102000.ticsi2rx context 1" -v width=2592,height=1944,pixelformat=BGI0

    The above configuration will be supported out-of-box in the upcoming SDK 10.0 release.

    Regards,
