Maybe I missed something but:
@dmitrystu My bad.
I wonder how should I modify the files to add support for those chips?
I have created two boards, one with STM32F405 + USB3300 for stm32f429_otghs_ulpi
, one with STM32F446 + USB3343 + USB mux for stm32f446_otgfs
and stm32f446_otghs_ulpi
. And I have a STM32F767 Nucleo that can allow work on stm32f767_otgfs
.
Those chips are some of the newer high performance chips, and for STM32F446 I am planning to use it in a project. They uses an updated OTG block so existing STM32F405 code will likely not work.
STM32F446 is similar to STM32F405 that it has an
OTG_FS
block with internal PHY, as well as anOTG_HS
block with internal FS PHY and ULPI pins.STM32F732 is part of the new STM32F7 line. The
OTG_FS
block is similar to that of STM32F446. ItsOTG_HS
block features internal HS PHY and ULPI pins.For STM32F446, it need three drivers:
otgfs
,otghs
andotghs_ulpi
. For STM32F732 it needs onlyotgfs
andotghs
. Since the internal PHY forOTG_HS
in STM32F732 is already a HS PHY, there is no point except for compatibility reasons to use external PHY at all, so that more-or-less redundant feature can be left unsupported.
