That happened to me as well.? The fix that worked for me is to go into the device manager, locate the USB port section, find the port that is giving you trouble, and then update the driver.? When asked for the driver location, use the root of the folder where the DFU software is installed.? Once that driver is updated, you’ll see your device, and the fix will carry over (you won’t have to do this again).

It's at step 8 that I run into trouble - the app doesn't show the device. If it did, I'm sure there would be no problem.

Computer running Win 10 latest 64 bit.
1. Plug in USB cable to computer
2. Turn on SA
3. Plug in cable to SA
4. On SA open menu and go to config
5. Go to DFU
6. Make sure Enter DFU is highlighted
7. Start DFU Demo on computer
8. It should show an STM device in demo mode at top of screen
9. Go to Eric's site and download the DFU to the download folder on the computer
10. On DFU Demo go to bottom right and select "choose"
11. It goes to the download folder and then click on the DFU file
12. Click on upgrade, takes abt 3-4 seconds.
13. Turn SA off and the back on. It should come back up ready to use.
14. Close DFU demo.

These are the exact steps I followed and have been following, no fancy setup, nothing

Yes, I put DFUdemo on my wife's laptop, and it too didn't find the tinySA, which was in DFU mode.

In the folder shown below, I opened the version.txt file, and it said to double-click on dpinst_amd64.exe for a 64-bit system. I did that in the Win10 folder, and it installed the driver. But dfusedemo still doesn't see the device (in DFU mode), and the tinySA app still gives gives the result I posted in an early screenshot. In other words, no change. BTW, thanks for your continued help. Hopefully there will be a Duh! moment soon.

Hey Terry, apparently the DFU driver is not loading and showing up in the USB Devices section. This driver (two of them) are installed with the DFUdemo program from ST Micro. I’m not around my computer right now but I’ll look it up when I get back home. It’s possible something went wrong when the ST program was installed. Your ST version number is the same as mine so should be compatible. Look in the program file under ST Micro and see what drivers are listed. Again I’ll look at mine and send you a screen shot later. I am using both Win10 and Win7 with no problems. You mentioned you tried the update on your wife’s laptop, did you also put DFUdemo on it?

Rename the downloaded file to tinySA.bin

Connect the tinySA with USB, switch the tinySA on and enter DFU mode.

Download dfu-util from and check you can execute it.

For windows, open a command window and go to the folder with the downloaded files and run DFU_LOAD_BIN.bat. The tinySA should now be updating with the tinySA.bin file using dfu-util-static.exe

I did the?above on a W10 PC.

On Linux and Mac make sure dfu-util can run from the command prompt. Go to the folder where you downloaded and renamed tinySA.bin and execute

Good Morning Terry, Take a look at this to see if the unit is setting up correct drivers as noted by Ignacio:

1. Go into Device Manager and look at the ports section. Connect the TinySA and turn ON. A new ST Micro port should show up as COM PORT #.

Rename the downloaded file to tinySA.bin

Connect the tinySA with USB, switch the tinySA on and enter DFU mode.

Download dfu-util from and check you can execute it.

For windows, open a command window and go to the folder with the downloaded files and run DFU_LOAD_BIN.bat. The tinySA should now be updating with the tinySA.bin file using dfu-util-static.exe

I did the?above on a W10 PC.

On Linux and Mac make sure dfu-util can run from the command prompt. Go to the folder where you downloaded and renamed tinySA.bin and execute
dfu-util -a 0 -s 0x08000000:leave -D tinySA.bin

Hey Terry, what FW version do you have loaded in the TinySA (menu=CONFIG/ VERSION)? And, when connecting to the TinySA app (before you try to update) does everything work Ok, you get a sweep and can control the unit from the app?

It appears the program is not sensing the unit is in DFU mode. Does the TinySA appear to go into that mode when selected in menu= CONFIG/DFU/ENTER DFU, before trying to upgrade?

Perhaps one of our group more familiar with this might have some suggestions.?

Just copy to a file on the computer that you can browse to when the program requests it.

And Windows 10 needed to recognize the tinySA as a usb device- running zadig helped get it recognized. ?

I've viewed a couple of YouTube videos, and can't figure out what I could be doing wrong. Also, if I click CHOOSE and select the new .DFU file, the application reports that the file doesn't have the correct format. Seems I have two different issues.

Libre de virus.

Hi Terry, a very basic question: Did you updated the firmware ever before? If not, probably you don't have the correct driver for the DFU mode, this is not the driver used to communicate with the PC apps. The DFU mode driver comes with the dfusedemo app and without it the firmware can not be uploaded.
