SMP/AMP mode setting about SCU configuration register in zc7020

Hello Expert,

 

I am trying to boot a  zedboard with SMP mode and seeing some problems which are not easy to identify.  After checking the configurations, I found that the value of SCU's configuration register is 0x531. So it looks that core 0 takes part in coherency while core 1 does not. Since this is a read-only register, I can not understand that since this is a multi-core processor, why one core is designed to not take part in coherency? Is there any ways to modify it?

 

My another question is: if one core is not taking part in coherency, then I think this SOC cannot run with SMP mode safety, could you confirm?

 

 

Thanks in advance!
