STM32U595 fmc dma burst size limit of 8 bytes

[Woody]

 For STM32U595, I use DMA for the FMC interface, and the maximum burst size is only 8 bytes,
How can I increase the burst size?

Hi @Woody ,

Based on this table from AN5593, the maximum burst length depends on GPDMA used channel and data width:

In STM32CubeMX interface, Data Width & Burst Length are parameters that you can configure once you select the channels to use, on channel dedicated tab.
