Hello daixiwen,

I have connected my packet memory according to your previous post

1. S1 of packet memory is connected to m_read & m_write of SGDMA

2. S2 is Connected to the data master of CPU

by doing so data master bus clash with flash (please see the attached print screen of SOPC) if i remove flash connection , there is no reset vector for CPU

as you mentioned in your previous post, please suggest how do i direct the memory allocation function to use packet memory..or what changes do i made in ipport.h..so that the memory allocation functions use the packet memory.?

With Regards
