QDMA on ZCU106 board not recognized by Host

Jump to solution

Hi

I try to use QDMA IP on the ZCU106 board (xczu7ev-ffvc1156-2-e) but it is not recognized by the host (lspci on ubuntu host). 

I use the example design of QDMA on Vivado 2019.2.
I tested XDMA IP and all is ok,  but QDMA is not recognized.

According to the state of PL-LEDs user_resetn='0' user_lnk_up='0'.
(sys_resetn='1' and user_clk_heartbeat[25] toggle)

I also try to use the pcie debug :

Is there a specific configuration for QDMA on the ZCU106 board ? 

 

Thanks,
Nicolas

In the QDMA IP configuration, if the board interface for pcie is not Custom, the lane width is X16 and can not be changed.
I have to set Board interface to custom to be able to change the Lane Width to x4 which is the maximum for ZCU106 board.

Then the board is recognized by Host

 

If set to pci express x1:
