hello Daixiwen,

I have add the tightly coupled data master to the CPU, individually connected to the packet memory's s2 interface.

and connect the m_read and m_write masters to the packet memory's s1 interface,

after that i have assign the base address through menu-->assign base address

i have got the two error saying "descripter_memory.s1:appear at more than one address" and "ddr2_bot.s1: apper at more than one address", though i have reassign base address but nothing happen and these two error remain there.

please see attached print screen of my sopc builder , am i doing wrong connection ..?
