XAPP1052 64 bit AXI support

Hi,

 

I'm using XAPP1052 ( Bus Master DMA Performance Demonstration Reference Design). It works perfectly fine when I configure the core in 128 bit AXI mode. I have used the driver and the software app to read data from the FPGA and it works fine.

 

However, I want to use 64 bit AXI mode since I'm planning to use this in a X1 PCIE bus. When I configure the PCIE core to 64 bit,  mode and set the parameter C_DATA_WIDTH at the top level to 64, the driver gets incorrect data from the FPGA. Looking at the code it seems that BMD_128_RX_ENGINE and BMD_128_TX_ENGINE would only work for 128 bit case.  

 

May I know whether there's a 64 bit version of the BMD?

Have you consider trying the xdma IP

that is DMA/Bridge for PCIE , and it can be found in IP catalog
