Configuration example for ADV7182 decoder with IMX6 Solo processor

marcosal — Thu, 22 Nov 2018 15:05:33 GMT

Hello everyone,

I have a custom board that has an IMX6 Solo processor and it is connected to a video decoder ADV7182. I want to configure it to capture video from an analogue camera. I have seen many examples and applied some patches but I cannot even see a printk I wrote in the probe and init methods from the i2c/adv7180.c file. I am using kernel 4.9.88 and I activated in the kernel configuration the options:

CONFIG_V4L_PLATFORM_DRIVERS=y
CONFIG_VIDEO_MXC_OUTPUT=y
CONFIG_VIDEO_MXC_CAPTURE=y

CONFIG_VIDEO_MXC_IPU_CAMERA=y
CONFIG_MXC_CAMERA_OV5640=m
CONFIG_MXC_CAMERA_OV5640_V2=m
CONFIG_MXC_CAMERA_OV5642=m
CONFIG_MXC_CAMERA_OV5640_MIPI=m
CONFIG_MXC_CAMERA_OV5640_MIPI_V2=y
CONFIG_MXC_CAMERA_OV5647_MIPI=m
CONFIG_MXC_TVIN_ADV7180=y
CONFIG_MXC_IPU_DEVICE_QUEUE_SDC=y
CONFIG_MXC_IPU_PRP_ENC=y
CONFIG_MXC_IPU_CSI_ENC=y
CONFIG_VIDEO_MXC_IPU_OUTPUT=y
CONFIG_VIDEO_MXC_PXP_V4L2=y
CONFIG_SOC_CAMERA=y
CONFIG_SOC_CAMERA_PLATFORM=y
CONFIG_V4L_MEM2MEM_DRIVERS=y

If more information is required please let me know. Any clue or recipe would be great.

Thanks in advance!

Hi Marcos

for adv7182 configs one can look at sect.6.1.1.2 OV5642 Using parallel interface

attached Linux Manual, dts file and driver sources:

capture\mxc\platform\media\drivers - linux-imx - i.MX Linux kernel

linux-imx6/imx6qdl-sabrelite.dtsi at boundary-imx_4.9.x_2.0.0_ga · boundarydevices/linux-imx6 · GitHub

Best regards
igor
