When I analysis the package of the MPC8548 SRIO, I found it just can't send complete Nwrite package. I use the DMA and don't bypass ATMU unit, I have set the WRTYP field of ROWARn as 0100(NWRITE). But when I capture the SRIO package of MPC8548, the type of the last package is Nwrite_R. It confused me. Can MPC 8548 send all of the package as type NWRITE(including the last package)? Can anyone give me some suggestion? Thanks!
By design the DMA always issue NWRITE_R on the last payload of the DMA transfer. There is not a way to prevent this.
