TI中文支持网嗨喽，我有一个DM368的开发板，使用的sensor为MT9P031。
我有将内核make menuconfig 里的其他解码器去掉。选中MT9P031
有在static struct vpfe_subdev_info vpfe_sub_devs[] 添加
.module_name = "mt9p031",
.is_camera = 1,
.grp_id = VPFE_SUBDEV_MT9P031,
.num_inputs = ARRAY_SIZE(mt9p031_inputs),
.inputs = mt9p031_inputs,
.ccdc_if_params = {
.if_type = VPFE_RAW_BAYER,
.hdpol = VPFE_PINPOL_POSITIVE,
.vdpol = VPFE_PINPOL_POSITIVE,
},
.board_info = {
I2C_BOARD_INFO("mt9p031", 0x5d),
/* this is for PCLK rising edge */
.platform_data = (void *)1,
},
},
我的bootargs为
setenv bootargs dm365_imp.oper_mode=0 mem=48M console=ttyS0,115200n8 noinitrd rw ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs video=davincifb:osd0=720x480x16,4050K davinci_capture.device_type=4;
现在内核启动信息出现问题为：
i2c /dev entries driver
Linux video capture interface: v2.00
ths7303 1-002c: chip found @ 0x58 (DaVinci I2C adapter)

请问该如何解决呢？
Chris Meng：
你好，
建议使用IPNC的软件。对RAW输入支持更好。
JUKE CHEN：
回复 Chris Meng:
恩，这个是我基于以前同事的基础上改的，他之前有什么添加改动我没法乱改。 IPNC可以作为实验测试。现在我这个MT9P031 出现的问题是怎么造成的的呢？该怎么解决？谢谢了。
JUKE CHEN：
回复 Chris Meng:
DVSDK 4.02 存在MT9P031传感器的驱动吗？
你能给我个明确的答案吗？
还有如果不存在？ 那个 kernel/drivers/media/video/mt9p031.c 这个文件是什么作用呢？
Chris Meng：
回复 JUKE CHEN:
Juke,
能否修改davinci_capture.device_type=3，再试试？
http://processors.wiki.ti.com/index.php/U-Boot_Usage
davinci_capture.device_type=This defines which driver to use. Use the following settings:
davinci_capture.device_type=0 for MT9T001 davinci_capture.device_type=1 for TVP5146 davinci_capture.device_type=2 for MT9T031 davinci_capture.device_type=3 for MT9P031 davinci_capture.device_type=4 for TVP7002
JUKE CHEN：
回复 Chris Meng:
我将 davinci_capture.device_type=3 for MT9P031 还是不行的。就是检测不到MT9P031芯片。 而且没有/dev/video0设备节点。 我使用i2c工具 i2cdetect -y 1 也没有检测到 0x5d的设备地址。
Chris Meng：
回复 JUKE CHEN:
Juke，
EVM上是没有MT9P031sensor的，你是外部接了一个sensor到板子上么？
JUKE CHEN：
回复 Chris Meng:
这是我的板卡。 我是自己制作了一块MT9P031 sensor的板卡，拆了一个旧的摄像头。
Chris Meng：
回复 JUKE CHEN:
Juke，
你使用的不是TI的DM36x EVM。
能否尝试vpfe_capture.interface=1？

回复 Chris Meng:
嗨 Chris Meng
还是不行的,我的I2C设备地址 为0x5d。这点我确认的。

Juke，
感觉可能是sensor板的问题。你能否测量一下sensor板上的时钟等信号是否都正常？如果正常，测量一下I2C上的信号。
