I am trying to create an application for EXANIC X10 and learning about the process. The only material I found is the "Cisco Nexus 3550 FDK User Guide - Overview [Cisco Nexus 3550 Series] - Cisco.pdf". Is there any more detailed material to guide to the Firmware creation? For instance, I am getting warnings when running make PLATFORM=x10 VARIANT=eval TARGET=bridging_example CRITICAL WARNING: [DRC HDTC-19] Stage 1 Tri-state IO buffers should be driven by Stage 1 cell: Tri-state buffer 'sfp_i2c_scl_IOBUF_inst/OBUFT' has been added to Tandem stage 1, but the driving logic on the tri-state pin 'exanic_x10_devkit_inst/instance_0d901239223aa6dfd670fa433d6ad513' is part of stage 2. This will result in undefined behavior on the tri-state pin for the stage 1 IO. To correct this condition, the cell driving the tri-state pin for stage 1 IO should also be added to Tandem stage 1 design. No idea what need to be done. I noticed that if NOTANDEM=1 is added to the make call, it does not appear but on the other hand NOTANDEM=1 is not recommended.
