Trying to connect two FS devices to an STM32F722RET. Datasheets are a little vague, but seems it should be OK as long as I don't do HS.
Using cubeMX, and for the FS port (PA11/PA12) - things work great. For the HS port (configured to be host_only, FS 12mbit) - I'm getting nothing.
Traced things back to OTG_HS_IRQHandler, which never fires, so phost->gState stays in HOST_IDLE.
Not sure where to take it from here..
