Topic:VSS3530 saMmapLoopback fails <--- 〖Reply to this〗
Hi 
just got 2 VSS3530 boards.

Trying to test video input using the supplied saMmapLoopback program.

I get ...

[root@OMAP3EVM /]# saMmapLoopback
tvp514x 3-005d: tvp5146m2 found at 0xba (OMAP I2C adapter)                      
                                                                                
Capture: Opened Channel                                                         
VIDIOC_G_INPUT: Invalid argument                                                
Error in opening capture device for channel 0                                   
[root@OMAP3EVM /]# 


I am booting with the software that came flashed with the board. Can you suggest what
the problem might be?

I can"t find the source code for saMmapLoopback. 

I notice the program is reporting a tvp5146m2 decoder chip. The decoder chip on the
VSS3530 is actually a tvp5150.

I am using an NTSC (not PAL) video source.
Please help. 

Thanks
Steve

Dear Sir,

What type camera interface you have ? BNC or S-video ?

I am using the BNC composite input connector on the VSS3530 and have an NTSC video
source connected.

thanks,
Steve
