HAL_TIM_IC_Start_DMA() with dma I am not getting the raising or falling edge ?

I am using the stm32h745 nucleo . I am working with the timers and I am getting the falling capture of the cm7 pulse and going in to the callback function when I am using the HAL_TIM_IC_Start_IT() and also I am able to debug the both cm7 and cm4.

But I am not able to do the same thing While I am using the HAL_TIM_IC_Start_DMA() for finding the falling edge. Even I am not able dbug the cm4 when the cm7 is running.

Anyone could you please suggest me how can I do this.

Thanks

Sm
