I am using STM32F746-Discovery.
I run USB in high speed mode.
Internal DMA is enable.
But, if I use ICache and DCache my host is't initialization.
Who will tell me what the problem is?What am I doing wrong?
You shouldn't DMA to/from cached memory. DMA accesses directly the memory. Read the related application notes you find on the 'F7xx product pages.
