Hello,
I am working on a fast USB Virtual Com Port communication using USB HS
external PHY. I am using USB3320 ULPI PHY. My application needs to have
a cache
enable. When I have tried to enable USB DMA when Cache is enabled device
fails
to enumerate. I used STM32CubeMX to generate an empty project with just
the
VCP, DMA and Cache and it still fails to enumerate. A similar problem
was
described in the post: https://community.st.com/s/question/0D50X00009XkgGb/stm32f777vi-usb-enumeration-fails-with-dma-enabled
Are there any solutions to this problem?
