Unable to read data from h2f_master port from HPS linux

[Manikanta123]

Hai Team,

I'm  using Agilex board and trying to interface  Axi4Lite IP to HPS via h2f_master  port and wrote small application in linux to read from h2f_master port but we are unable to read data  from read channel of the AXI4-lite port.

When i'm trying to read the data from h2f_master memory mapped address ,it is always showing zeros on memory mapped address.

could please let us know what could be the issue

Here i attached the screen shot of the design and the port is highlighted.

Hai Jingyang,

  Sorry for late replay .Thanks for you continuous support. We wrote our own AXI interface protocol  in verilog and all the channels are working fine when interface with HPS via H2F master port.

Regards,

Manikanta
