Hello,

 

I am trying to interface the TVP5147M1 Video Decoder with i.MX53 processor through its CSI1 Interface port.

The Decoder is interfaced with 8-bit data bus, DATACLK, HSYNC & VSYNC of CSI1 Port.

 

The camera output is a composite VGA resolution video which is connected to TVP5147M1 Composite Video Input port.

 

With use of Camera test application i was trying to test the video steaming. Upon execution of test command, i am getting few errors, the log for the same is provided below.

---------------------------------------------------------------------

 

The Video decoder is able to get detected during the boot up through the I2C interface which is used for configurations.

 

After 10 seconds of above test command execution, i am seeing a blurred back & white still image on LCD seen by the  Camera.

The LCD Display is connected on LVDS0 port of i.MX53 processor.

 

Has any one successfully integrated TVP5147M1 Video decoder with i.MX53?

Please let me know if i'm missing anything.

 

Thanks in advance!!

 

Regards,

Gopi
