Posted on November 04, 2013 at 18:54Hi,
I have to write a Flash tool for the STM32 Family via USB. So I have tu use DfuSe API. I found the demo DfuSeDemo where everything works fine (the button ''Leave DFU mode'' too). Now I ported the code step by step in an own Windows console tool. But currently I have a problem on the operation OPERATION_RETURN. Function STDFUPRT_GetOperationStatus always retruns the Context.ErrorCode = STDFUPRT_UNEXPECTEDERROR. I already read the user manual UM0384 but did not found any hints. I checked the device name, the content of the image and the content of the mapping between both tools but I cannot find a difference. Has anybody an idea where is my mistake?
Here is my code:
lstrcpy (Context.szDevLink, szDeviceName_l);
Context.DfuGUID = GUID_DFU;
Context.AppGUID = GUID_APP;
Context.Operation = OPERATION_RETURN;
STDFUFILES_CreateImageFromMapping (&hImage, pStdfuMapping_l + 0);
STDFUFILES_SetImageName (hImage, (LPSTR)(LPCSTR) pStdfuMapping_l->Name);
STDFUFILES_FilterImageForOperation (hImage, pStdfuMapping_l + 0, OPERATION_RETURN, FALSE);
Context.hImage = hImage;
dwRes = STDFUPRT_LaunchOperation (&Context, &dwOperationCode_l);
if (dwRes == STDFUPRT_NOERROR)
{
do
{
Sleep (100);
STDFUPRT_GetOperationStatus (dwOperationCode_l, &CheckContext);
if (CheckContext.ErrorCode != STDFUPRT_NOERROR)
{
...
break;
}
else
{
...
break;
}
}
while (1);
}
