Resolved! I have an product using a STM32l486. It uses USART1 with transmit and receive DMA to communicate over a serial port. Serial port packets are all the same length. My application works in run mode, but not in sleep mode.

I can send and receive packets in run mode, but I never get a RX DMA interrupt when in sleep mode. I do not have any interrupts enabled in the USART hardware, and do have DMAR and DMAT enabled. Any ideas on what might be missing?Thank you.
