STM32H7 USB Host

[jh9]

Hi,

What is the meaning of the FRMOR flag for an INT OUT transfert as a FS Host? How and why can that be raised? HPTXFSIZ seems to have enough space (PTXSA 0x0203, PTXFD 0x0102) in a FIFO that is mentioned to be 4kBytes in the datasheet. The frame I try to send is 1024 bytes.

Cheers,

jh.

Really? Are you aware of the transfer size limits of the full speed protocol?

Thank you for the reminder!
