STM32F446 + USB3320

[Xelus22]

Hi Luantty, im not sure where else to communicate to you. But is it possible to get a STM32F446 + USB3320 config? I've been testing to try with the USB OTG HS but i am unsuccessful. :(

How does your board.h file look like?
OTG HS won't work without D0-D7, CK, STP, DIR, NXT pins defined, so that's pretty much all the config you need.

OK thanks ill have to try on the weekend. :)

Hi Luantty, sorry I haven't had time to do this until now. (yes a very long time)

Ive found that the STM32F446 uses a slightly different Alternate value for the D4 pin.

How should i edit the board.h to reflect this?

I have edited it to this here. (i think i am correct)

Testing:
Fails to enumerate now, previously wasnt able to start USB at all.

Problem Code : 43 (CM_PROB_FAILED_POST_START)

Hi,
I haven't looked too deep into your config, but generally looks correct and should work.
There might be a hardware issue that stops it from working?
