Trying to figure out how to add UDP and TFTP to LwIP using the RawAPI

Ok, any specific STM32 platform? Custom board?

STM32F765 CPU, custom board, using STM Cube generated code without an RTOS. It should be a simple question. I am trying to incorporate TFTP so that I can easily update internal code. I am having a problem getting a handle on how to incorporate this into this code set. Unfortunately, I cannot determine how UDP decides that a TFTP request has been made from a TFTP server so that I can route the packet to the appropriate TFTP process code.
