Genesys 2 LwIP echo_server project creation

[SeanS]

Hello, I was following the instructions here https://reference.digilentinc.com/learn/programmable-logic/tutorials/genesys-2-getting-started-with-microblaze-servers/start

to build the echo_server example project, but project creation failed in step 11 with the following SDK Log:

I am running Vivado 2018.2 and have upgraded all IP to their most recent versions.

In Vivado, I have tried deleting the microblaze_0_axi_intc interrupt controller and re-instantiating it, making sure to have Vivado Auto-assign the address, but once I try creating the project again in SDK the same error gets thrown.

Any ideas what could be causing the error?

I did some research on Xilinx.com and found this answer record:

https://forums.xilinx.com/t5/Embedded-Development-Tools/XSDB-Server-ERROR-Hsi-55-1545-Problem-running-tcl-command/td-p/834915

I had two floating inputs on my concatenation block and once I connected these project creation proceeded correctly.
