Hi,
I have a compulab SBC (UCMiMX8Mplus sbev) it is a dev kit.
I am connecting the STEVAL-55GMBI to the board with the edge connector with our custom board. It is connected to the MIPI-CSI2 connection.
I have build the vd55g1 driver with the kernel and the driver is being loaded.
Although it does not create the subdevice nodes in the v4l2-ctl --list-devices.
I do see errors regarding the setup :
[ 10.219820] mx8-img-md: Registered sensor subdevice: vd55g1 4-0010 (1)
[ 10.219837] mx8-img-md: subdev_notifier_complete error exit
[ 10.219847] mxc-md 32c00000.bus:camera: Sensor register failed
[ 10.219853] mx8-img-md: Unregistered all entities
[ 10.219857] mxc-md: probe of 32c00000.bus:camera failed with error -515
I have attached the schematics of the adapter board that we have created to connect the SBC to the ST camera board.
Could there be some issues with the driver configurations ?
