SPI Global Interrupt cannot be disabled when DMA is used for SPI in Cube MX V6.5.0

[TA1]

I cannot disable SPI global interrupt in SPI Settings--> NVIC sub settings when DMA is used for SPI. When DMA is activate, SPI global interrupt check box became deactive. I am not sure if it is a problem or not. I suspect from everything because I have faced many problems in V6.5.0. I have an old project for STM32F745 and SPI global interrupt can be disabled in NVIC settings. Therefore I suspect about it.

you can check my sample ioc file.

Hello @TA​ ,

After further check, it turns out that this is a normal behavior. For all STM32H7 MCUs, the SPI global interrupt must be enabled when DMA is used.
