Can't run video_copy on DM8168

zhengyang wu

I'm using a DM8168 with EZSDK 5.04.00.011 and I can't get the video_copy example to run. The version of Codec Engine is 3.22.01.06.

Wu,

Looks like you are trying to allocate memory from the kernel's memory area using ioremap. Can you share your kernel bootargs?

Wu,

Can you try to reduce it, say some where around 100M and see the behavior?

Wu,

Also can you try to adjust the "phys_start=0xa0000000 phys_end=0xa07fffff" values? Looks like it is only 8MB memory that you've allocated for cmem.

Hello Renjith

I reduce the bootargs to 100M and it can run well.

Thank you very much
