Here is the translation of your post using Google translate:
What is the relationship between DMA burst mode and FIFO? It means the same thing.
In STM32F7 MCU, burst mode is only available when FIFO mode is enabled.
When setting burst mode, the FIFO threshold should be compatible with burst size.
For more explanation, I advise you to take a look at the application note: AN4031 Using the STM32F2, STM32F4 and STM32F7 Series DMA controller.
Also, you can attend the available training in the ST website.
