I'm trying to get this example to work with my custom hardware. The TX works fine. I can't get the RX to work.* This example was developed for the NUCLEO-F411RE board and my processor is an STM32F439ZIT6, not F411. Could this be the problem?* I ha...

Yes, thank you Piranha for your helpful comments. I did read the chapter in question. This chapter clearly states that the DMA must be restarted. While I'm sure the information I need is embedded in this text, it would still be nice to have some e...

Yes, the Rx interrupt from the DMA stream. Yes transfer did complete with the first message. Can you provide sample code that shows how to restart the DMA? I tried running the Configure_DMA(); again after receiving the first message, but even that...

OK, I now have the Rx interrupt working once and only once. It works the first time after starting the program, but all subsequent messages are ignored. Is there some flag that needs to be reset upon receipt of the first message?
