USB HS on STM32H7 supported ?

Hi,

Is the USB high speed (with external ULPI PHY and DMA controller) supported on H7 ?

I'm looking to start a project that requires high speed (~10-15MB/sec) USB rates, so my first inclination is to look at H7 chip at 480Mhz. I've seen posts here that mention F7 HS USB working, but couldn't find any mention of H7.

Hi,

The DMA is not yet supported, the external PHY is untested on H7 but it works on other devices with the same OTG.

There is also one with internal high speed phy: STM32F730Z8. And apparenltly some STM32F7x3 devices.

I have a board with an STM32F730 on it but I haven't had time to test the second USB port yet.
