USBx Msc not working on STM32H563-Nucleo board

[sourcerrer]

Hi,

 

I have got the filex + levelx working with qspi nor flash chip ( 16 MB size )along with threadx.

However I am not able to get the USBX MSC to work to see the files by attaching the STM32H563 Nucleo board to a PC.

But the USBx stack doesn't seem to work. I have checked and used all the code from a ready STM32H573 discovery project give by ST Micro.

The USBPD stack uses the  void USBPD_DPM_Notification(uint8_t PortNum, USBPD_NotifyEventValue_TypeDef EventVal) function to call start the USB interface.

But the USBPD_DPM_Notification() doesn't get called.

 

I am unable to get the USBx CDC ACM working along side Filex as well.

Hello @sourcerrer 

First, are you enabling the TrustZone?

Hi @FBL ,

I have not enabled TrustZone.

 

The device class does not get enumerated. i tried for both the ACM and storage class.

The ACM+HID ready example is working on my Nucleo-H563ZI board.

The USBPD is working. I had not added the stm32h5xx_nucleo_usbpd_pwr.c file in the BSP folder.

Hi @sourcerrer 

If I understand correctly, ACM is not working alone. But works on ACM+HID example. 

I propose you to start with ACM+HID and comment out ux_hid_thread! 

Otherwise, can you point me directly to the issue linked to mass storage?
