Hello Renesas Community,
We are developing a custom board using the RZ/G2L.The output signal of the camera unit is input to the RZ/G2L in parallel for the CRU. (YUV422_16bit)MIPI-CSI is not used.The camera unit automatically outputs video after the system is powered on, so no control from the RZ/G2L is required.Therefore, we believe that I2C drivers such as sensor drivers are not necessary.
I'm trying to create a dts file using the following as a reference, but /dev/video0 is not created. There is no evidence in the kernel log that the CRU driver has been loaded.
Accessing Digital Parallel Interface for camera module instead of MIPI.
I think I need to install some kind of dummy sensor driver so that /dev/video0 can be created.With this system configuration, could you please tell me how to support the kernel in order to input parallel to the CRU?
Regards.
Hi morimori,Can you please share your dmesg log?Is it connected on i2c0?Do you use the adv7180 video decoder?What is the output of the commands: i2cdetect -y 0media-ctl -pKind Regards.
Hi, PT_Renesas,
Thank you for your reply.I have attached the following files.
・dts settings・dmesg log・Configuration diagram of the custom board and camera unit
When the power is turned on, the microcomputer inside the camera unit sets up the camera and the camera unit begins outputting video data.Simply turning the power on will cause the camera unit to continue sending video data permanently.Therefore, there is no need to configure the camera unit from the RZ via I2C, so there is no I2C connection between the RZ and the camera unit.Only the video signal is connected between the camera unit and RZ.
The question is how to configure the kernel driver in this configuration.In the attached dts, /dev/video0 is not created, and it seems the CRU driver is not loaded either.I think it will probably be necessary to create a driver for an empty camera unit that does not set any H/W settings (registers, GPIO pins).Otherwise, I believe there will be no way to provide information such as video resolution.
