Hello lin, I meet the same problem with you .
As you say "I updated IBL to apply to our board and have implemented pcie bootmode. Now we use pcie bootmode.
The cause for enumeration failure is that pcie switch has used a SSC ,but DSP and swtich doesn't use a
common clock source. Now the PC host can enumerate two DSPs and allot resources to them"
what is SSC? what did you do to solve this problem . my C6678 use local clock ,not same with PC.
can i have your email?
