NetFPGA 1G CML Getting Started Guide - Error at Step 3

[eertraw90]

Hello,

i just tried the 'NetFPGA 1G CML Getting Started Guide' tutorial and run into an error at Step 3 (make cml_cores).

Can someone help me out?

Thank you!

Hello,
It seems like you are using a Vivado version which is more recent that the one supported by 1G-CML. You need to update the version numbers of some IP cores (namely, pcie_7x and MIG) used by the project. The following did the trick for me:

diff --git a/lib/hw/std/pcores/dma_v1_20_a/data/pcie_generate.tcl b/lib/hw/std/pcores/dma_v1_20_a/data/pcie_generate.tcl

Also, you might want to have a look at this commit, as going to version 3.3 of pcie_7x will require some code changes.

Hope that helps!

One problem about this issue. After modifying the files pcie_generate.tcl and mig.xco, "make cml_core" seems do nothing as follows:
/////////////////////////////////////////////////
//nf1_cml_interface installed

....
Is the PCIe core installed with this?

tried to make clean first?
