H264/MPEG4 encoder does not work on DM6446 DVEVM when booting from NAND

libin

If DM6446 DVEVM boots from NOR flash with this u-boot(u-boot-567-nor.bin), the H264/MPEG4 encoder works perfectly.

But if the DVEVM boots from NAND flash with this u-boot(u-boot-567-nand.bin), the H264/MPEG4 encoder does not work anymore. It stuck at the encoding process.

The kernel and filesystem are totally the same. So I think it is because of the u-boot. Perhaps somehow some part the chip is not enabled, like the DSP module.

I also tried the latest u-boot-1.2.0 for NAND flash. Does work either.

Do you have a quick answer for this?

Thanks.

Libin,

Are you booting kernel via TFTP and file-system via NFS (to esnure they are the same) in both cases? If not, can you try this. I will give this a try myself tomorrow (working off-site today).

Yes. The kernel is through tftp and the filesystem is nfs. The kernel is built from the latest download of DVSDK.
