Timer + DMA: CubeMX inits Timer (And DMA stream in HAL_TIM_Base_MspInit) before DMA peripheral.

[DavidAlfa]

CubeMX 6.5.0, CubeIDE 1.9.0

No matter what I do, CubeMX always generates this:

/* Initialize all configured peripherals */
 MX_GPIO_Init();
 MX_TIM2_Init();
 MX_DMA_Init();
 MX_TIM3_Init();

While it should be:

/* Initialize all configured peripherals */
 MX_GPIO_Init();
 MX_DMA_Init(); // <-- DMA first!!
 MX_TIM2_Init();
 MX_TIM3_Init();

So DMA fails miserably.

This is an old known problem recurring for years.

Perhaps a good warning point to consider abandoning clicking in favour of normal programming .
