USB HS Device DMA is broken?

[P?�?�]

Hi, I am working on USB HS Device and Host applications with STM32F7 family (STM32F745ZGTx). Initially DMA on both of them didn't work at all. It's well-known bug, which still not fixed (http://we.easyelectronics.ru/STM32/stm32f4-usb-hs-dma-hal-kak-eto-bylo.html)

I used bugfix from link above, now host works pretty well, but on device some output messages are still broken. In Wireshark I can see them as EINPROTO or EREMOTEIO. If i disable DMA, all works fine.

Does anyone stuck with the same problem? Thanks for any help.

The article you linked above says it has been reported here, I guess it's this one https://community.st.com/s/question/0D50X00009XkZzuSAF/stm32f4-usb-hs-hal-driver-bugs
