HOW TO GIVE JPEG IMAGE INTO DM6437

Karthiraj,

I don't have the exact solution. But looking at the problem, what I understand is the following. When you feed a live image the data might not be compressed. It might be in a raw format which can be RGB/YUV format. When you are giving a JPEG input, which is a compressed format, which will not be recognized by your simulink. So better you try and uncompressed format. 

Thanks for your reply Renjith..

           Already I stored JPEG image in my PC. How to give that JPEG image to my dm6437 board..And how can i view the output of that image..

Help me Renjith.

Karthiraj,

I don't have a DM6437 board setup to tell you exactly what to do. But I've given my idea on what is wrong with what you are attempting in the previous post

Hi Karthiraj,

Is there any issue in using file operation for reading and writing back JPEG streams through a debugger like JTAG? Do you have this set up?

Hi Karthiraj,

Please see if you can use "fread" in your program to read the jpg file from PC and allocate buffers (malloc) in your program. Once fread is successful, the jpg content is available in the buffer which is in DDR.

Hi Karthiraj,

You dint answer for the question " how to view the output of this image in another monitor",from where should we have to take output wheather from DAC or S -Video outputs...............?

your answer is appreciatable and m facing same problem.

thank you.
