Issue in STM32H563ZI SAI_DMA Configuration

[Srmssenthil]

Hi,

 I am using PDM mems microphone to configure the STM32H563ZI SAI_A with GPDMA. I have attached the image of configuration details. After configuration I generate the code, But GPDMA initialization details not showing in the code.

Hello @Srmssenthil and welcome to the Community :),

GPDMA initialization code can be found in the generate stm32h5xx_hal_msp.c file.

I tested this behavior with STM32CubeMX6.12.0 version and the GPDMA is well initialized in the generate stm32h5xx_hal_msp.c file.
