Technical Support Request for STM32U585 - Low Power Mode and UART DMA Issue

Dear STMicroelectronics Support Team,

I am working with the STM32U585I-IOT02A development board, and I need assistance with the following:

  • Entering and waking from low power modes (STOP2 or STANDBY) using the RTC wakeup timer
  • Configuring UART1 with DMA and ensuring it resumes correctly after waking up
  • Handling interrupts before and after sleep modes

I have tried implementing the configuration using STM32CubeIDE and HAL libraries. However, I'm encountering issues where UART DMA does not resume correctly after wake-up.

I would appreciate any official guidance or example code specific to STM32U585.
