About REZ function of DM365.

gomo

Hi all:

At recently, I had meet a very strage problem.

On DM365, program based on IPNC, I get YUV422 data(pix:2432x2050 ) from ISIF, use RSZ to convert to YUV422. and then contrast the data in hex like this:.

After RSZ, Compared to original data, I found two lines in front have missed, it start from the third line. and the last two line repeated two times.

I have no idea about the setting of RSZ.

Anybody can help me?

Thanks a lot.

The IPIPE/RSZ the width of the input image is limited to 2176 pixels on DM36x.

In this case, clearly, the width is beyond the limit (H=2432 > 2176).

Yes, I know the limit of width. I had split data to two part , resize and combinate with EDMA. It's not the problem.

Anybody have idea?

The RSZ does not have any known problem like what you encountered.

To see what is wrong, you may have to explain more clearly on how you implemented it.

What is problem you see on the RSZ output for each half after your splitting?

A register dump of the resizer will also be helpful.
