"tm32cubeprog_v2-5-0": API-Error with Windows 7

Hello everybody,

I am actually a PC software developer, but would like to be able to update the firmware of the hardware we have developed with our own software.

For this purpose I have downloaded the "en.stm32cubeprog_v2-5-0.zip" and installed the Windows version on a Windows 10 (64 Bit) PC.

I tried the example "1 example with UART bootloader" from the STM-API.

This also works very well under Windows 10/64-bit.

(A Windows 10 with 32 bit is unfortunately not available to me for testing)

But when testing it with Windows 7 (32 / 64 Bit, both the same effect) I get an error when calling the API-function

"connectDfuBootloader".

Code:

   if ((usbConnectFlag = connectDfuBootloader(dfuList[0].usbIndex)) == 0)

   ...

The value in "usbConnectFlag" is then equal to "-5", which according to the API description "STM32CubeProgrammer_API.chm" means something like:

"Operation not supported or unimplemented on this interface".

When using the original GUI-programm of STM it works on Windows 7.

So the driver(s) should be OK. I hope so.

Is there any known problem/bug with Windows 7 and the API?

Or am I doing something wrong?

Please excuse me if I have not yet provided important information, but I am absolutely no expert in the embedded world ;)

Hardware:

Evaluationboard "NUCLEO F072RB"

# Update #

I have now put this question to support.

If I get a satisfactory answer there, I'll post it here.

Hello again,

I found the bug and it was - how could it be otherwise? - my mistake.

The polluter:

I did not adhere to the required tree structure of the individual files completely correctly.

There must be two directories in parallel on one folder level:

The "Data_Base" directory with its xml files and a directory of any name,

in which all necessary dlls belong.

Unfortunately I had the dlls and the "Data_Base" in a common directory.

Well, ashes on my head.

But if I can help only one person who is also confused by the rigid required structure of directories,

the whole thing would ultimately have something good.

Hi Gneifel !

I am currently running USB_Example with the STM32Cube Programmer API and I have the exact same error. I copied the files to my own directory. I'm probably missing something. Did you mention that you need to properly configure the directory structure? What is the exact solution?

Regards,

Kamil
