### DPS Stall in DM6446

Hello

 

I have a custom board running with DM6446. The ARM AND DSP clock rates match the eval board from TI. We are running DDR2 at 32-bits at about 110 MHz, slightly slower than eval board.

When using the "encode" sample from TI, we get what appears to be a DSP stall. Meaning, it will run along fine encoding at 30fps. Then one frame will take nearly 500ms to 1 second to encode. The encoded frame is correct in the MPEG output stream, but we obviously drop our inbound frames. We have worked around this a bit right now, and are encoding at 15fps. Input is NTSC/PAL/D1

This seems like an internal bus contention or huge cache miss or something?

Can someone assist please?

Thanks
