Camera Module

  • sys_config.fex config

See the 13 chapter page 37 to page 52 sys_config guide


  • kernel menuconfig

                       <M>   imx317_mipi sensor driver

the imx317 sensor driver code

kernel/drivers/media/platform/sunxi-vin/modules/sensor/imx317_mipi.c

if you want to support a new sensor, you can add the driver code in this path, and modify the Makefile and Kconfig like imx317. Of course you should config the sys_config.fex first.


  • insmod the sensor module

1.cp the driver ko to debian/target/lib/modules/4.4.55+/

2.replace the imx317_mipi with the new sensor ko's name in this file

device/eagle/rootfs/etc/modules-load.d/mpp.conf

3.build the sdk


  • User Interfaces

1.Use the MPP interfaces. see the MPP Interface Usage page 20-53,

The demo code is here sample_virvi2vo

2.Use the /dev/videoX directly, you can see the demo in Camera Driver Guide
