Dear USRP users and Ettus support team , 


I synthesized your Vivado project for XG Ethernet from the E320 FPGA folder. I 
noticed that the AXI crossbar connects the e320_core design with the e320_ps 
side. I understand that the e320_core design processes commands based on 
timestamps. However, I could not find an example project for Vitis that helps 
me understand how this is controlled on the SDK or Vitis side. 

Specifically, I observed that the e320_core part is connected to the m_axi_xbar 
which maps to the address range 0x4001_0000 to 0x4001_3FFF. I believe the 
timekeeper accesses this range with specific offsets, but please correct me if 
I am wrong. 

I am aiming to develop and deploy a design on the board using Vitis. 

Could you please assist me with this? 


Thank you.
