Hi:

I got stuck trying to use STM32 Connective line controller towork as a USB HOST. If I attach flash drive the device attaching is detectedbut the enumeration is not working. USB Control packet is send but the devicealways returns URB_STALL (as per USB OTG flag). I tried different devices sameresult.

Anyone has any suggestions?

Thanks,

Konstantin

It is gcc 4.5.2.

Just eliminate the uint16_t_uint8_t type and substitute with uint16_t and change the code where it is being used. Example:

typedef union _USB_Setup

{

  uint8_t d8[8];

  struct _SetupPkt_Struc

  {

    uint8_t           bmRequestType;

    uint8_t           bRequest;

    uint16_t        wValue;

    uint16_t        wIndex;

    uint16_t      wLength;

  } b;

} 

USB_Setup_TypeDef;  

I have to warn you that I am still encountering problems with this firmware and it seems nobody ever bothered to test how the code behaves when GCC is used as compiler.

Thanks,

Konstantin

This is strange ! Does it mean that GCC is not able to compile/recognise the union...? Changing the union type to uint16_16 will probably affect other parts to code.

By the way, Petrov, can you share with us the firmware you want to run ? Mass-storage or HID ? Do you have any other compiler, for which the workspace is already available in library ? I tried mass-storage and HID both with IAR, it works fine ! The project was already available in the lib ;-))

Hi alokm

Did you connect USB keyboard? I tried to connect to keyboard with STM3210C-Eval board but didn't get keyboard data. Get VID, PID and Enumeration was done propely. What's wrong? Thanks.
