STM32PRGFW-UTIL not working in CP_Serial_boot with USB DFU interface

[pdematteis]

As reported in the GitHub page, STM32PRGFW-UTIL should work with boards with USB DFU or UART serial interface.

It works properly with UART, but it doesn't with USB DFU, showing the following error:

The code seems to ignore USB requests, since GetCommandOpcode is not defined:

 

 

 

static OPENBL_OpsTypeDef USART_Ops =
{
 OPENBL_USART_Configuration,
 NULL,
 OPENBL_USART_ProtocolDetection,
 OPENBL_USART_GetCommandOpcode,
 OPENBL_USART_SendByte
};

static OPENBL_OpsTypeDef USB_Ops =
{
 OPENBL_USB_Configuration,
 NULL,
 OPENBL_USB_ProtocolDetection,
 NULL,
 NULL
};

void OPENBL_CommandProcess(void)
{
 uint8_t command_opcode;

 /* Get the user command opcode */
 if (p_Interface->p_Ops->GetCommandOpcode != NULL)
 {
 command_opcode = p_Interface->p_Ops->GetCommandOpcode();

 switch (command_opcode)
 {
 case CMD_GET_COMMAND:
 if (p_Interface->p_Cmd->GetCommand != NULL)
 {
 p_Interface->p_Cmd->GetCommand();
 }
 break;

 

 

 

Does somebody know how to get it working properly?

Thanks!

Hi @pdematteis 

 

Can you specify which product/board ? 

 

Thanks

Hi,

it's a custom board using STM32MP157F processor.
