Cannot find DMA FIFO in Host.VI

[john308]

I am using the USRP2944. In the "Simple NI-USRP Streaming" example, I created a new DMA FIFO (host to target) in FPGA, but I can't find this FIFO when I reference the FPGA handle in host.VI. I can't solve the problem? my computerhost.VI

Right-click on that Refnum constant wired into the primitive that casts the FPGA interface.  You will have to update the underlying type by importing the compiled bitfile or the FPGA VI... then it will find the new controls, indicators, and FIFOs you may have added.

Wow, I have to say that I am very grateful for your reminder, it turns out that I overlooked this detail. Now that the problem has been solved, and thank you again ！
