This defines an overlay for the dma channels when executing the tests/drivers/uart/uart_async_api on stm32 nucleo boards:

  • disco_l475_iot1
    through overlay for this tests.

The DMA must be configured for the UART when asynch api is defined.

on disco_l475_iot1: UART 4 is used for testing : DMA 2 channel 3 & 5 and request 2 is selected (uart4 is already selected for this board)

UART Tx pin must be connected to UART Rx pin on the board.
It also helps when running the test on other stm32 boards or running other test (ex. tests/drivers/spi/spi_loopback) with dma on those boards.

tests: drivers: uart stm32 run uart_async api on l475 disco
f87cf25 
This sets the dts of dma for using the uart asynch api.
The stm32l475 has a dmamux with request 2 for Tx/Rx usart4
The Tx&Rx pins (PA0, PA1) of the usart4 are connected
on the disco_l475_iot1 board to pass the test.
