A problem about burst read in ADV212

Hi.

I  met a problem when i use ADV212 for encoding YCbCr image. I use the burst mode to transfer data to/from ADV212, and the EDMODE0 is set to 32'h01120000 while EDMODE1 is set to 32'h01100000. When i finish all burst writes and  and read the first busrt length of compressed code, the begining of which proves to be the head of JP2, which seems correct. The question is that when the second time of burst read goes on, the data read from the ADV212 are tatolly the same as the data i read in the first cycle of burst. And the rest data from burst read are also the same as the data read in the first burst read cycle.

Could it be the mis-configuration in encoding and indirect registers?

 

Thanks

LEE
