Two questions : I2c error and arago install.

when I use NFS to boot dm365 and run the  encode demo. It prints follow message.

root@192.168.0.222:/opt/dvsdk# ./encode -v test.264 -y 2
Encode demo started.
i2c_adapter i2c-0: tvp514x_setinput:lost lock]
i2c_adapter i2c-0: tvp514x_setinput:lost lock]
i2c_adapter i2c-0: tvp514x: no input connected
i2c_adapter i2c-0: Set input failed, err = ffffffed
vpfe ccdc capture vpfe ccdc capture.1: vpfe_doioctl:error in setting input in decoder
Error: Failed to detect video standard, video input connected?
Error: Failed to create video encoder: h264enc

I have rebuild uboot,but  still no working.

Another promblem is about arago. I follow http://arago-project.org/wiki/index.php/Setting_Up_Build_Environment  to set up bulid enviroment, on the step of bitbake arago-base-image,the shell print :
ERROR: Importing sqlite3 and pysqlite2 failed, please install one of them. Python 2.5 or a 'python-pysqlite2' like package is likely to be what you need.
I install two package, but still print the same message.

 

Anybody who can help me!

  • Hello,

    Is the video input connected? Also is the input standard correct? I think -y 2 corresponds to PAL video (not sure, but you can get this information from command help).

     Is python in your $PATH?

  • Thanks for replay!

    I have connected a camera using PAL video. And the demo can be run success before some days.

    The uboot and filesystem are made by myself.

    I guess if the device such as 5146 is broken? Otherwise the driver ?
