�?STM32F446(WLCSP81)】 How can I implement DMA for UART5.

SNaga.4

I have an application for STM32F446.

And I want to use DMA for UART5.

But I can't set DMA for UART5 on STM32Cube IDE.

Specifically I would set it on Device Configuration Tool And I would set DMA Request for UART5.

But ​There is no choice for UART5 on DMA Request.

How can I do it?

Hello SNaga.4,

let me welcome you to ST community. It should not be a problem to configure DMA for UART5. First you will enable the UART peripheral with setting the mode. Then you can in the DMA tab click on Add and there you are able to select the UART5_TX or UART5_RX DMA request and related setting. Please see attached screenshot:
