Does C6670's SRIO support IDLE2?

Expert 2985 points

Hi all

we connect the C6670 to a IDT's SRIO switch. The lane map is below

DSP           SWITCH

Lane0---->Lane3

Lane1---->Lane2

Lane2---->Lane1

Lane3---->Lane0

We want to open the C6670's IDLE2 sequence.

In the SRIO datasheet, it says that the DSP supports it. But I can not find any detailed information about how to open it.

Just find the USE_IDLE1in the PLM_SP_IMP_SPEC_CNTL reg and the bit near the USE_IDLE1 bit is reserved which I find it is USE_IDLE2 in ccs. But I can not set it.

Can anyone give me some helps?

Thanks!
