有一个DM368的开发板，使用的sensor为MT9P031，将内核make menuconfig 里的其他解码器去掉，系统出现我问题了该怎么解决？

你好，
建议使用IPNC的软件。对RAW输入支持更好。

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,
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 MT9T001davinci_capture.device_type=1 for TVP5146davinci_capture.device_type=2 for MT9T031davinci_capture.device_type=3 for MT9P031davinci_capture.device_type=4 for TVP7002

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。

Juke，
EVM上是没有MT9P031sensor的，你是外部接了一个sensor到板子上么？

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。 

Juke，
你使用的不是TI的DM36x EVM。
能否尝试vpfe_capture.interface=1？

 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。
