Hai Jingyang,

  • We have only option to test the incoming data to HPS from Custom IP's of AXI read channel is done through user application or devmem .
  • In u-boot, reading the incoming data through md command.

We checked this three methods and in all three methods we are getting zeros.

Note: The Custom IP is generated from Xilinx HLS and we are using those RTL files for Quartus in agilex board.

Other than AXI read data channel all other channels(AW,W,AR) are working fine.

Regards,

Manikanta
