B-U585I-IOT02A USB Host

Hello forum, 

I'm trying to setup my B-U585I-IOT02A as a USB host. 
Ive turned on the following:

  • USBPD - Type C only, TIM2, enabled USB support 
  • USBX - core, Host CoreStack FS, Host Controller FS, MSC
  • USB_OTG_FS - Host Only
  • UCPD - Source
  • FileX - FileX Core

to initiate I've used these in my main:

 

MX_USB_OTG_FS_HCD_Init();
ux_host_stack_hcd_register(_ux_system_host_hcd_stm32_name,_ux_hcd_stm32_initialize, (ULONG)USB_OTG_FS,(ULONG)&hhcd_USB_OTG_FS);

 

It seems I don't get the any power out to my USB flash drive, and the USB event callback doesn't work.
am I doing something wrong? am I missing something? thanks in advace

Hello @ElectroManiac 

Could you share to us a trace .cpd file please ? Using the tracer tool here.

To check if the attach state is reached. Because in Type C, before turning on VBUS, the CC lines must be checked.

In the trace, check if there are notifications sent by the USBPD stack to the USB part.

The mechanism is described here.

Regards,

Nicolas

Hello @Nicolas P. 

the CubeMonitor UCPD doesn't recognize the USB-C of the board,
What should I do?

Hi @ElectroManiac.

You need to add the embedded trace tool. See this wiki.

Have you tried looking for the COM port directly (clicking on the blue top right panel) ?

Hello @ElectroManiac 

Please check the Vbus generation, this should be managed by the TCPP03

    Hi @ElectroManiac 

    You may need to share the full project. According to your IOC, you are using full stack configuration for USB PD application not type C only as you mentioned in initial post.

    @FBL its because I kept trying to make it work, after a couple of days of trying to make everything compile I succeeded but the "ux_host_event_callback" doesn't activate, and the UCPD software still doesn't recognize the board/app
