Hello,

 

I'm trying to output video throug the AD7171 stamp,

 

I have just plugged the AD7171 board on the BF537-STAMP

 

but I don't get really nothing with "video-test" or "jpegview"

 

I use the uclinux-dist-R2008 but I find only the AD7393 in the menuconfig.

 

Can I do this ?

 

plz help me

 

Regards

ADV7171 is an encoder, not a decoder.  it doesnt make any sense to try and use programs that generate video ooutput with it.

7171 is never supported by blackfin uClinux release since 08R1. Use 7393 instead.

Hello

 

 

Thanks Mike and Sonic for your reply

 

 

Yes I see that the ADV7171 is an encoder (ITU-R BT601/656 YCrCb to PAL/NTSC Video Encoder), so we can output an PAL/NTSC signal through it ??

 

 

Sonic, can I copy the ADV7171 frame buffer files from the R06 to the R08 drivers directory and configure them with the menuconfig ?

 

 

Regards

If you copy it from 06 to 08, you are on your own.
