I's using STm32CubeMX to generate code for 429's OTG-FS. But I find there is a grayed option 'USE_BUFF_WO_ALIGNMENT', it's fixed to 'Enable', and on USB_OTG_FS configuration wizard, the 'Enable internal IP DMA' is fixed to 'Disable', why? Does it mean F429 OTG-FS can't use DMA?

Hi,
DMA transfer is only available in HS mode, but you can using the OTG HS in Full Speed mode to achieve your goal.You can look into the STM32F4 and , that can be helpful for you.Regards
