Hi Andrew, Quick thoughts: - Are you setting SIMPLE_MODE(0) in the axi_wrapper? - Are you propagating tuser into and out of the axi_rate_change block?
The axi_rate_change block updates tuser, which the axi_wrapper uses to create output packets when SIMPLE_MODE is disabled. Also, have you run in a simulation testbench? Simulation should be able to expose these issues before targetting hardware to make debugging a bit easier.
