IMX6 Linux Adding Driver Module

janr_ — Fri, 06 Jun 2014 09:49:12 GMT

Hello Community,

I try to add a driver for ar0330 aptina image sensor in linux.

Here are my steps:

1. Adding a new entry on the ltib Catalog

ltib/rpm/BUILD/linux/drivers/media/video/mxc/campture

=> Editing the Kconfig file

I added this part.

config MXC_AR0330

tristate "Ar0330"

depends on !VIDEO_MXC_EMMA_CAMERA

depends on ARCH_MX6Q

select MXC_MIPI_CSI2 if ARCH_MX6Q

select MXC_CAMERA_SENSOR_CLK

---help---

If you plan to use the ar0330 Camera with mipi interface in your MXC system, say Y here.

2. Editing the Makefile

I added this part:

ar0330-objs := ar0330.o

obj-$(CONFIG_MXC_AR0330) += ar0330_camera_mipi.o

3. I copied the file ov6540_mipi.c and renamed it to ar0330.c

4. Tried to build linux

Error:

make[4]: *** No rule to make target `drivers/media/video/mxc/capture/ar0330_camera_mipi.c', needed by `drivers/media/video/mxc/capture/ar0330_camera_mipi.o'. Stop.

I can't find any camera_mipi.c file for other sensors, however they dont cause errors.

Do you know how to solve the problem?

King regards,

Hi Jan,

suggest to look at

把 ar0330-objs := ar0330.o 这句删掉. 把 ov6540_mipi.c 改为 ar0330_camera_mipi.c.

ar0330-objs := ar0330.o

obj-$(CONFIG_MXC_AR0330) += ar0330_camera_mipi.o

--->

ar0330_camera_mipi-objs := ar0330.o

obj-$(CONFIG_MXC_AR0330) += ar0330_camera_mipi.o
