Zynq UltraScale+ MPSoC Processing System IP - AXI ACP Limitations

Description

The ACP interface on Zynq UltraScale+ MPSoC accepts only the following (cache-line friendly) transactions. Masters targeting ACP should account for these limitations:

  • 64-byte aligned 64-byte read/write INCR transactions. All write-byte strobes must be the same (either enabled or disabled).
  • 16-byte aligned 16-byte read/write INCR transactions. Write-byte strobes can have any value.

All other transactions return an SLVERR response.

Solution

Transaction converter code is currently not planned to be provided by Xilinx. 

Consider using the coherent HPC ports instead of ACP which have broad AXI transaction support along with coherency.
