Debug tvp5150 in DM365 circuit

Other Parts Discussed in Thread: TVP5146, TVP7002, TVP5150

I’m debugging a circuit of DM365, which is designed by us. At the same time, TI’s design has been as reference. The embedded system can run, and burning flash is ok. I have removed tvp5146, tvp7002, mt9t001, mt9p031 and so on. When it runs demo, it is error. The error is like this:

 

root@ DVS365:/opt/dm365# ./encodedecode                                    

Encodedecode demo started.

 layer.pix_fmt.width = 720,                                                    

 layer.pix_fmt.height = 480,                                                   

 layer.pix_fmt.sizeimage =529920                                               

DavinciDisplay DavinciDisplay.1: pixfmt->width = 720,                          

 layer->layer_info.config.line_length= 736

vpfe ccdc capture vpfe ccdc capture.1: vpfe_get_std_info: Error in set std in decoder

Error: Failed to detect video standard, video input connected?

When I type “./encodedecode” again. The error has changed. It’s like this:

 

root@ DVS365:/opt/dm365# ./encodedecode                                    

Encodedecode demo started.

I want to know, what does result in this problem? What shall I do?

 

Thank you.
