Posted on December 23, 2014 at 17:38I am using
STM32F103ZEH6 ARM.
I am running PC side application that is written in C♯. The application is able to upgrade the firmware of the STM32 by using the DFU mode for this process.
Sometimes error is occurred while calling the STDFUPRT_CreateMappingFromDevice method (from
STDFUPRT.DLL
)
Here is the C♯ code of importing STDFUPRT.dll
[DllImport(''STDFUPRT.dll'')]
public static extern Int32 STDFUPRT_CreateMappingFromDevice
The parameters that I am passing to CreateMappingFromDevice are:
Device link array in ASCIIEncoding representation � holds the device path
pMapping � pointer to a mapping structure
numberOfAlternates - The number of memory units that are exposed for DFU operations
In ''no error''case after calling this function I receive the �pMapping� and �numberOfAlternates� that are initialized and filled with the values from device.
Sometimes error is occurred the error number is - 0x12340006 or 305397766 - ''Error Descriptor Building''.
Is there any document that describes the STDFUPRT.dll functionality especially the STDFUPRT_CreateMappingFromDevice method
with description of all Error cases?
What causes the error? In which cases it may happen?
Thanks.
