How to read GPIO data [8-bit of Port D] uisng DMA1 of STM32F429 MCU ?

[Rajesh1]

We have configured TIM2 Channel 1 to capture rising edge on PA0 pin.

We have enabled DMA1 Stream5 to read data on Port D and copy to local array.

The callback function for DMA1 is not triggered.

Please let us know, if we are missing any configuration.

Note: We are using STM32CubeIDE version 1.5.1 for our project.

I don't use Cube.

Read out and check/post content of TIM and DMA (and perhaps GPIO) registers' content.
