no DFU device found?

 

I'm trying to update the tinySA.? I works well with the Windows PC app and communicates as expected.? I am able to put the tinySA into DFU mode and it shows up under dive manager as STM32 Boot Loader with no driver.? Neither the tinySA application firmware uploader or the ST.com uploader "see" any DFU devices.? Any thoughts on what I'm doing wrong?

Nothing wrong... just unfinished.

The DFU drivers are available from the ST website.
If you install DfuSE it includes the drivers.

You can use Device manager to manually change the "STM32 Bootloader" driver for the one in C:\Program Files (x86)\STMicroelectronics\Software\DfuSe v3.0.6\Bin\Driver\Win10
(assuming a 64bit W10 installation)

Try using STCube, it's much more user friendly than DfuSE.
 

Perfect Mike.? Installed the driver manually and all is well.
Thank you!

Great news!
I had the same problem, so I knew straight away how to resolve it.

Thank you, thank you, thank you, thank you, thank you... thousands TANK YOU!!! After getting crazy with other complicate and unsuccessful solutions. It solved my problem finally. I understood that it was a driver problem, but I couldn't imagine that the proper one was easily available in that directory. My tinySA had an old fw (October) without the new convenient shortcuts and now it's?finally provided with them. All the best!
 

Thanks Mike. I had the same problem yesterday.
