  1. Hello, I'm trying to get http://www.digilentinc.com/Data/Products/ATLYS/Atlys_AXI_Web_Server_Demo_v_1_02.zip to work on my Atlys board but I'm running into errors in SDK. After I clean & build, the elfcheck passes: 10:39:52 **** Incremental Build of configuration Debug for project Atlys_Webserver_Demo **** make all 'Building file: ../src/additional_sf_ops.c' 'Invoking:
